What Orthman Manufacturing Sees for 2020 Compaction Studies

Sending you all who consider this website/webpage a spot to be informed about the Strip-Till World as it turns with Orthman Manufacturing and the World Leading 1tRIPr regarding plans for more studies in the field hopefully in four states what is happening in the spring with Soil Compaction.  We are looking at what are the levels of (severity) of compaction in Conventional tilled fields, No-Till fields and then Strip-Tilled fields – mainly corn.  This last year – 2019, we measured some expected and not-so-expected numbers in moist to nearly wet conditions that surprised the farmers and then we saw Mohawk root conditions which limited growth and nutrient uptake.

Then later in the year before harvest we heard that corn fell over due to a couple of nasty days of winds 60mph+ with blown over corn due to Mohawk root systems and weakened stalk health due to plant health from maybe fertility uptake.  All not good.

As we reported here back this early fall, the amount of force that a young plant before V4 stage in corn, only has a limited amount of energy and push power at the root tips – up to 60psi.  But our measurements with a penetrometer showed even in loamy sand soils some conditions of 160psi resistance in the soils at 7-8 inches in a strip-tilled field.  Corn growth was slowed until it had a bit more age then went on, but yield was impacted just the same.  Now when the corn reachs V8 stage it has up to 160psi of force at the root tip to extend, but with soil density reaching levels of 400psi – oh the plant is going to struggle.

The image to the left is quite dramatic due to sidewall compaction which we measured this last spring after planting with a newer method of lateral compaction testing.  The smear really can do a number on the root systems growth potential.

So folks, this fall we should have a more complete set of results to share with you after we measure fields again this coming spring.  It is not our intent to bash anyone, but to offer field testing numbers that we know about and what is happening with the Strip-Till world and using technology to advocate being the best you can be in raising corn whether it is naturally rainfed or irrigated.  So please stay tuned.

2019 Pioneer/Orthman Strip-Till results with Pioneer 9 Hybrids – Nebraska

From cold Colorado where the temperatures have dropped to near zero, snow from 3 to 12 inches in places which sure puts the ‘Ky-Bosch’ on getting harvest done, but back in Nebraska where the weather did not hit quite as quick the lads at North Forty Pioneer dealership, Polk, Nebraska shared with us their yield results which we aided and abetted their work with the Orthman 1tRIPr and some fertility placed in the tillzone.  Nick Hatfield informed us he was pleased with the results in a cool and wet year that hovered over that part of Nebraska.

The lads finished harvesting last week.  These were all 4 row plots on 30 inch rows.  What the guys are shooting for and we at Orthman have been advocating is to keep the inputs of Nitrogen as low as we can and not knock the plant health or yield.  A bit of scrutiny but the results speak highly of what Nick and Dennis accomplished.  Total with pre-plant, starter, sidedress operations and late season applications was 200.3 lbs of N.

With that we can count and calculate the amount to produce 230bpa up to 267bpa ranges from 0.87lbs/bushel to a low of 0.76lbs/bu.  Those of us involved with this plot and others continues to be raise top notch yields on the least amount of pounds of N per bushel.   Our question to you, is this a possibility on your farm as you raise rain-fed or irrigated corn?  Now this happened to be lightly irrigated corn near Polk, Nebraska.

The out-of-date thoughts of 1.1 to 1.5lbs N/bushel which has been the recommendations for a long time in a conventional tillage systems is not as efficient and ecologically minded as what we promote with the Orthman Strip-Till System approach.  We are working with growers in the Sandhills of Nebraska and Colorado that are tweaking their fertility programs and management to reside at 0.65-0.75lbs N/bushel corn yields.  Placing N and other nutrients right in the pathway of the dominant portion of the downward growing root system is absolutely the method to make this happen and to split apply in the growing season.  It is still important to meet the plant needs at the critical physiological times.  When growers learn and make this a program for their farms and fields, they grow some pretty fantastic crops.  Understand everyone that the skies have to be favorable before dry down.

We at Orthman are very pleased for Nick and Dennis who cooperate with us on several endeavors to promote wise stewardship and conservation practices in east central Nebraska. Congratulations guys!  More to come from other growers in the coming days.

Tillage by a tractor pulling some sort of an implement has its ramifications, good or detrimental.  Earthworms also in a manner till the soil, they are tunnelers seeking other critters (nematodes, amoeba, fungi, bacteria, and protozoa) as food sources along with exuded proteins, sugars and carbohydrates of all kinds left from plant roots.
I have been reading partially for recreation and also to bring you more “soils stuff” from written materials that I subscribe to or access via libraries [call me old fashion] or get via interviewed articles in Agricultural magazines.  So I read some incredibly interesting information from Dr. Paul Hepperly a scientist that has had a tenure at The Rodale Institute, Ohio State University regarding worms that live and work in our soils.

Interesting Facts:
1.  Worms love soybeans, high nutritive value
which aids in worms in reproduction and vigorous life
2.  Plowing is very hard on worm habitat – usually 50% less populations than conservation tillage systems.
3.  Worm castings aid in carbon sequestering and stabilizing carbon in soils – castings are up to 26% carbonaceous material.
4.  Worm castings are rich in calcium which is important to nutrient uptake from roots.
5.  In moderately acid to acid soils calcium is important to helping soil structure and aggregation
6.  Worm castings are rich in iron in an available form, chelated
7.  Earthworms lay cocoons which contain 1 to 5 eggs
8.  Each cocoon goes through a gestation period of 1-5 months depending upon worm species
9.  Baby worms hatch, are active immediately and become sexually mature within 3-12 months
10. Worms can produce 10 pounds of organic amendments in 1 season
11. Worms are active 2 times during a year; spring and then when soils cool back down after a warm summer – they prefer soils that are 48 to 63 degrees F.
12. Synthetic fertilizers can be detrimental to worms and toxic – especially ammonia
13. Nitrogen in the worm castings is in the nitrate form rather than ammonium
14. In acidic soils liming will aid worm populations, reproduction and worm activity
15. Manuring when possible greatly aids the population of earthworms, both the vertical and horizontal burrowing worms due to the enrichment of animal gut species of microbes passed out thru manure.
16. Worms recycle manure into the soil beyond the soil surface taking it deeper into the soil profile

 

 

While we were out this spring (May and June) getting data to study soil compaction in very moist soils, we did some worm counts per square foot.  Strip Tilled soils at least 5 years running we were counting 10 to 18 worms.  Direct Seeded fields (No-Till) we counted 12 to 20 worms per square foot.  In the Conventionally tilled soils, so many less, 1 to 9 worms.  We also found worm cocoons, the most we found in the strip tilled fields, 2 to 7 cocoons/sq.ft..  Now one has to be looking very closely when you dig to see the little cocoons.  See the picture below.
As you can see with the man’s fingers the cocoons are quite small, probably 3/16ths of an inch up to 1/4 inch.  They are usually laid in the upper 10 inches of the soil profile in a warm environment but not hot.  I have seen earthworm cocoons not fair well in soils that reach 110 to 140 degrees F.

A wonderful scientist from Quebec, Odette Menard affectionately called ‘The Earthworm Lady’ whom I have met and had long discussions personally has studied earthworms at night being sexually active on the soil surface in a variety of soil residue conditions and all the incredible tunneling they do.  She has said  “Soil health isn’t just about the chemical make-up,” says Ménard. “The challenge is to talk about the soil with respect to its physical and biological properties.” And that’s where earthworms become important. These creatures help to aerate the soil, build and maintain soil structure, increase hydrology, improve nitrogen efficiency and reduce pests and diseases. Ménard also says farmers often worry earthworm tunnels will increase the chance of nutrient leaching within their soils, but that’s not the case. In fact, since earthworms stay close to living plant roots – often within one inch – their tunnels support overall root development. “More holes in the soil means the soil is actually in better shape,” she says. “And the better the soil, the more root development, counterbalancing leaching.”

For all of us to realize that with Strip-Till we can aid worms in their effectiveness in our soils.  It has been studied in the last 3 years that cover crops in No-Till and Strip-Till systems even provide more gains to growers in all kinds of climatic environments.  A couple years back when we at Orthman had the Bill Orthman farm as a experimental station to study strip-till effects for the beneficial fact finding and support of the Orthman Strip-Till Method; I carried out earthworm counts with a couple of our interns.  We were 6 years into Strip Tilling at the time and we were counting 15 to 32 earthworms per square foot, calculate that out per square yard using the average of what we counted, that is 620 worms being busy.  That is 3,005,640 worms per acre folks if everything stayed equal.  That is one whale of a lot of worms.  We also measured that summer soil infiltration rates; strip-tilled soils with high numbers of earthworms in those clay loam soils was 2.95 inches/hour compared to the normal USDA-NRCS Soil Survey data at 0.6 inches/hr. for a clay loam soil.  The advantages of combining worm tunnels and strip-till which is much less disturbing than conventionally tilled soils with plows or disk-ripper implements and a field finisher of some sort.

Down and Dirty Back in the Pits – Again … And Lovin’ It!

So for many of you the year has been a doozy with wet then dry and then wet, then hail for some that makes record size in the state of Colorado as well as fields obliterated and tussle with insurance companies.  During the week of August 13 & 14th we went up north into central Michigan and participated in the AgroExpo.  It was a great opportunity for folks to come and see what is working, what is new, what happens with high quality fertility ideas which all promote better ways to be more soils and water resources conscious and even more efficient.  Two of us from Orthman Manufacturing did our part to commuicate with growers the highly effective method of strip till and pre-plant nutrient placement.

Root pit at AgroExpo, fertility exhibit of five 6 row plots

With today’s population that live in the Great Lakes region, the issue of water quality, algal blooms, toxin waters for man, avian life and fish – part of the root cause has been pointed to the world of Agriculture and application of phosphorus either commercial or animal manures.  This concern has magnified itself a great deal in the last 4 years.  Lake Erie and Lake Michigan, both are in the lime-light of the public eye.  We at Orthman are much aware and can offer a role to play by suggesting the incorporation of strip till into the way farmers apply nutrients and till the soil.  Placing both phosphorus [P] and potassium [K] in the soil to reduce both mobile silt & clay running off the surface with phosphorus bonded to the soil and organic matter and soluble phosphorus that moves in and through the soils.  We had the opportunity at the soil pit-talks and at the Information Center at AgroExpo to address such and the smart move to place P & K in the upper portions of the subsoil or subsurface.

As you noticed from the picture to the right, we had a pit about 4 ft deep to show differences in root proliferation where starters were applied and other 6 row plots where there was no starter and follow-up changes in N-P-K applied in 30 inch row Pioneer 9608 corn.  As a soil scientist, I am a big believer in what the soil tells us in nutrient and water management via the  health, vibrancy and size of the root system.  I have dug in way over a thousand soil sites to reveal the real story below ground.   I thoroughly enjoy getting down at the moles viewpoint to see the morphology of soils, what has gone on since man broke the land, erosion or sustaining of the soil and what are the soils potentials.  The above-ground portion of the plant may appear okay, but dig down to 4 feet and we have a chance to reveal the secrets.  If the soils have far too much tillage I can tell, if the soils are compacted – I can tell, if the soils were not right (like too wet) I can tell.  Roots will always reveal the good, the bad or the absolute ugly.

So at this neatly done root pit we looked at what differences were visible and measurable from no starter and with part of the starter applied before planting with the 1tRIPr (AgroLiquid owns their own 6row-30) and part of the starter on the planter.  Oh significant differences both below ground and then 3 plant characteristics above ground to tell the story why starters have a “front row, center seats” importance to the crop.  First the root system of the no starter, had 80% of all the roots in the upper 11 inches, 11-16 inches was 15% and down to 34 inches was 5% by volume.  In the split applied starter plots, 65% by volume of the roots were in the upper 11 inches, 11-22 inches was 25% and 22 to 36 inches was 10%.  Clean sand and gravel was below the 36 inch depth and roots stopped there.  As you stare a bit closer at the soil pit image, at 29 to 36 inches below the surface was a layer of darker colored clay loam which sat atop the sand and gravel and both held water and slowed the movement of water rushing through and on out the bottom.  Comparing some more plant data; the height to the flag leaf in the split starter plot – 5% taller than that without, the size of the ear leaf on the split applied starter package from AgroLiquids was 11.25% larger both in length and width compared to the plot without.  The node-to-node spacing on the split applied was extremely even from the ground to the ear placement on the stalk in the split applied plot compared tow without.  The distance from the ground surface to the ear placement was somewhat erratic in the no starter, ranged from 91 – 115 cm.  In the plot where the starter is applied in two applications and times, 92 to 95cm above ground.  Very even and I look at 21 plants in a zig-zag fashion down through the plots measuring.  Darn good way to keep bias out of the observations.  Lastly I pulled ears, stripped back the husk and counted rows and length of the kernel set; in the split applied 18 rows around X 42 in length at 35,000 plant population, in the no starter, 16 around X 39 in length.  That is a difference of 132 kernels more on the split applied.  I believe all should say there is some significant differences.  The total amount of nitrogen remained the same across all 5 plots, with sidedressed nitrogen via Y-drops at 70 gpa.  Having the products applied directly with the seed at planting and then at 4 inches down directly below the seed and where the root will run right into more, so the plant incrementally gets a chance to consume good groceries.  Just what the doc ordered.

With this soil above the clay loam layer at 30 inches or so being a loamy sand it is both a concern and a reality that N will move downward and slow and be absorbed onto the clay where the roots can and did feed.  With more roots filling the upper 22 inches and remainder into the clay in the split-applied approach, the corn is showing what it likes.  AgroLiquids utilizes their trademark Pro-Germinator, Sure-K and Micro500 package for starter in these comparisons.

Over the two days my co-worker Adam Souder and I spoke with folks from all over central Michigan, Ontario Canada area, northern Indiana, the thumb region of Michigan, some folks from Utah, Oregon, Minnesota.  Our story stayed the same, managing your fertility in increments during the growing season will meet the crop demands better and does not fertilize the soil per se, feed the plant when it’s higher demand periods are.  Yes that depends upon what the sky throws at you but as close to those critical periods. AND remember it is not just about nitrogen; sulfur, potassium as well as P with micro’s are very important.

We at Orthman Manufacturing want to thank the AgroLiquid staff and field guys for all their efforts and potentials.  The two days were what we hoped they would be.

Recent News – Factoids of Root Growth of Corn Dealing with Soil Compaction

After attending the National Strip Till Conference (NSTC) in Peoria, IL the week of August 1-2, 2019; I got to thinking that more information to you all seems imperative from what we saw as negative impacts with the wet spring.  Growers that tried to do some tillage then planting when it was wet would want some clues of what we and you are noticing across the countryside.  Using the spring coulter system with the 1tRIPr in near saturated soils did induce some shallow compaction this spring at about 3 to 4 inches down as did planters with more than 100-150 lbs of downforce.  One of my co-workers and I measured some of those ill effects in the Platte River Valley of Central Nebraska.  We also measured where sidewall compaction was induced with planters and created the “mohawk” root system, not a good deal for the plants.  Where am I going with this?  See the image on left.

Sidewall compaction due to wet soil conditions Courtesy Anderson’s

In sandy clay loams, silty clay loams and clay loams – in a wet spring like this one the conditions were ripe for compressing the soils both downward and off to the side or laterally.  In the first 3 to 4 weeks of the corn plants life the root system develops out from the seed placement and down at a 25 degree angle parallel of the soil surface.  Squished and pressed wet soils deform out at a 25 to 40 degree angle from the tires or tracks.  When a farmer is running on dual wheeled setups and too high of pressure in the tires this will more than likely cause “pinch compaction” at depths of 3 to 7 inches deep.  With the rotating of the tires and the pinch-squeeze the soil presses out any air and crushed pores, channels, any kind of a gap and tiny early roots just cannot get through or down; ending up with serious concerns for water/nutrient uptake and stand-ability later in the season.

We have seen quite a number of fields across the Corn Belt with those symptoms.  Before the corn got to tassel time it did not seem to be an issue, now if storms come thru with big winds, folks could be in for problems.  University Extension folks have told me that in Minnesota and Northern Iowa they may be looking at 25% reduction in yields with compromised root systems due to compaction.

Another key point that farmers visited with me about at NSTC in Peoria, IL; what kind of information is out in the soils world did I have about root pits, root growth, compaction did I have that was new.  I have been digging (what else does a soil scientist do?) into the research and finding more information that details the amount of force a corn root can exert at its root tip to penetrate either wet compacted soils or soils that are dense and drying out.  Researchers in Scotland back a few years (2011) back wrote after work evaluating early growth in corn that corn feels the negative effects of soil resistance/compaction from 0.8MPa and at ~2.0MPa root extension stops.  At 2.0MPa (megapascals) corn plants at V2-V5 will curl up their toes significantly.  This amount of soil resistance of 2.0MPa is equal to~280 pounds per square inch (psi).  When corn plants get further into the season V8-VT the amount of turgid pressure at the root tip increases to give ‘push’ at the root tips at a force of up to 2.85MPa or 408psi.  A co-worker of mine and I looked at the very moist to nearly saturated conditions this spring when corn was V2-V4 and measured soil resistance in the seed-zone [1-5 inches] in silty clay loam soils in conventional till to be >250psi.  You can guess what we found, yes sir – blunted off roots, trying to make right turns and kinked.  The first two nodal root sets were blunted or just did not come out on the side where the soil was so dense, but the soil was wet to soggy.  Plants were short, first leaves were purple tinged – strong evidence of compaction when we dug around.  Unfortunately in the long term No-Till fields we observed this also and then with follow up field visits the corn is spindly, shortened, fewer leaves and when shaking a plant it is wobbly and not well anchored in the ground.  I am suggesting to folks take a good look at their corn fields and dig up a few of these kinds of plants and see what your root system looks like.  Small root systems with an appearance of being one sided or like the picture above, compaction either by pinch or smearing is an issue.  Freeze-thaw is not going to remedy this over time folks, other measures will have to be considered.

Looking ahead into the next few weeks; come to Husker Harvest Days [September 10-12, 2019] near Grand Island, Nebraska and visit us at the Orthman Manufacturing stand/booth for we are going to be presenting great information about our spring findings of 8 different soil types in Strip-Till fields, Conventional till fields and No-Till fields as to what two forms of soil compaction is happening in wet soil conditions.  Our guys will be happy to explain what we saw, what values are trouble and what is not a problem.  You bet I will be there ready to visit with you all any of the three days.  This data is not being done by University folks which is unfortunate, so we at Orthman want to bring you finding straight from the field and talk about what are options for pre-plant tillage.  After the show we will be publishing the results here on Precision Tillage.com.

From 118 years ago, Scientists at Univ.of Illinois are Giving Us Clues of Stay-Green Genetic Code

I just came across this exciting news for the “corn grower”, came via Corn and Soybean Digest, National Science Foundation (NSF) aided in the funding of this decade and longer study to doggedly keep at it to find out what was discovered to a degree those 118+ years ago.  Now unraveling the corn genome further and further these scientists wrote in Plant Biotechnology Journal April of this year what the NAC7 gene does.  Please click on the link below and read what Corteva, University of Illinois scientists, and NSF has accomplished.  This has big ramifications folks when we add small percentages of improvement in crop productivity with other management alternatives.  How to make more corn grow bigger crops takes every little move of the needle upwards to have a profitable higher yield than years before.

When corn gets moisture stressed in August and September the DNA switches to shut down the corn plant maybe 5 to 14 days too soon in the Northern Hemisphere.  As breeding moves forward this could be a lifesaver for some of the growers reading this.

Add it to your strip till system in the future, we can rock the boat folks.

Please take this as good news from the field.  What so many of us have heard is the Agriculture world as we know it is devastated and it is all falling into a heap. Yikes!  That brings no encouragement to anyone that makes their livelihood from the soils.

We at Orthman Manufacturing are supporting a project with a bright group of students at the High Plains Community Vo-Ag chapter in Polk, Nebraska about 1 hour west of the capitol city Lincoln.  These young men and women led by Vo-Ag instructor and adviser Tom Hoffman are working on a field sized project of 11+ acres (4.5ha) to study the advantages/disadvantages of common starter products in irrigated corn in a strip-tilled environment following the 2018 crop of soybeans.  This field is offered by a local grower very close to the high school and town. Orthman is partnering to provide manpower, scientist and Strip-Till equipment; a local fertilizer supplier is partnering to provide some of the nutrients, especially the starter products as well as herbicides, fungicides if necessary, and the local Pioneer Seed distributor is supplying seed products.  These folks are greatly appreciated and engaged.

First few days in the corn plants life.  [Courtesy:  Purdue University]

The students are involved with the project to make field measurements and sample the soils and crops for nutrients to determine how to grow a crop with both sustainability and best yields possible.  Mr. Hoffman has the students out in the field collecting data with myself, Mike Petersen, Orthman Agronomist as well as Pat McNaught, Territory Rep for Orthman to learn strategies and management principles that will enrich their education and maybe career opportunities long into the future.

At the V3 to V4 stage of the corn crop the students measured seedling root growth, height, plant density (population) to get an initial set of data to identify the effects of starter fertilizers compared to control with no starters used at the time of planting.  With this data the students will learn hopefully three key points; 1) Does spending the dollars (per acre basis) on better quality and plant-ready nutrients pay, 2) Can we say that yields will increase with starter packages in the seed trench which are liquid products, and 3) Why are starters even necessary in a corn-soybean rotation?  More questions are out there but these were three the students identified last winter.

Agronomically speaking, any grower that uses starter fertilizers are setting up their corn crops yield and growth potential.  So many will limit their thinking to does it affect yield?  We always hope so, yet so many things remain in the hands of each day of heat, cold soil and air temperatures, rain, no rain or no irrigation added, sunlight, wind, hail, insects, weed pressures, diseases, herbicide damage from the farmer or neighbors, additional fertility, soil compaction and the list goes on.  Starting with the best chances where the initial root system actively “runs into” nutrient sources before the soil microorganisms ramp up in their performance with warming soil temperatures is in my minds eye a “no-brainer.”  Besides folks, we are not talking about a glut of N or P or Zn or whatever, we are speaking about very small doses of nutrients.  Quickly, dispersing an ole myth; roots do not seek out nutrients, nor does it smell them or see them in the soil, the root has to literally run into them early on to be able to absorb the collective products.  So a widespread scattering of nutrients on the soil surface and maybe tilling them in as we have done in the past, the crop root efficiency of absorbing products which you spent money on is less than 30%.  That is why we are such strong advocates of precision placement both below the seed and in the seed trench.  It is one of our three guiding Strip-Till principles at Orthman.  Those first few hours/days after radicle root eruption from the seed itself is crucial for the root to encounter food sources to create as seen in the image above so with N,P,K,S and micros of Zn,Cu,Fe,Mn etc readily available for the miniature switches in the DNA of the plant cells to come on for growth potential.  I have explained it this way frequently; like in the back of a church auditorium the lights need to come on in the front and along the side walls for people to see as they walk in and sit.  Out of 25 switches only 13 need to come on for that time of entering.   Akin to that scene, these switches are turned on for the early stages of growth and movement of those elements into the leaves and stalk as well as the root cells to be used later.  As the root absorbs these nutrients the plant will develop with a certain potential, accelerated or maybe not.  The gene pool is activated to an advanced degree and now is influenced by water, temperature, and sunlight.  The entire process of cellular reproduction of leaves, stems, flowers, roots and photosynthesis can have a great beginning or one of … so-so.

The FFA students then walked back into the plots to sample entire plants in the different treatment zones to cut down at the ground surface to obtain dry weights of plants to gain a perspective whether the starter plus micronutrients offered benefits.  This was done at V5-V6 stage as shown in picture below.  The corn crops terminal growth point is right at or just above the soil surface at this time.  We are awaiting those results after air drying for a time.

Plant stage where students sampled for dry matter weight differences.

We will be making those results along with the other data collected on this website in the near future.  The young folks (young men and women) of the High Plains Community FFA Chapter will be putting together a report and presentation for the parents later on.

When any of us hear that they are going to minimize or not use starters in a high yield expectation of $300+ bag of seed corn could well have shot a hole in the foot before a 130 day walk.  Yep, not a good thing!  We are expecting big things out of those highly touted corn hybrids, they have great potential but then not using any starter products lacks foresight.  Sure I realize budgetary restraint for 2019 is a big rock in the road.  Trying to go around a huge rock on a road with a vertical wall on one side and 675 foot drop-off on the other with only 3 feet of room to spare is scary.  But so is the view screen of your yield monitor come fall that is bouncing down around 170 bushels per acre when you expected 225 bpa.  Ugh!

With this and more the students of this progressive and by the way Nebraska FFA has entitled this school in Polk, Nebraska as the number one rated FFA chapter of all the schools in Nebraska.  It is a great honor and pleasure that we at Orthman get to work with Tom Hoffman and ‘his’ young people.  They are learning very valuable lessons and principles in agronomics, a little about plant genetics, and what steps their parents make in growing corn or soybeans in East-Central Nebraska.  Mr. Hoffman is pouring into these young folks  what it takes to become leaders, Ag business professionals, farmers, cattlemen and cattle-women, scientists, teachers/educators and even crusty ole soil scientists.

Elite Up-and-Coming African Young Leaders Came to Visit

2018 Mandella-Washington Scholars

Everyone who has read stories and recent accounts of Nelson Mandella from South Africa and his journey/quest for Africa to awaken from their slumber and learn ways to feed, clothe and house their ever growing population would have seen and heard  promising words and hearts from these young men and women from 18 of the sub-Saharan region of the African Continent.  We, John McCoy, President and CEO of Orthman Manufacturing, Pat McNaught, Territory Manager and myself Mike Petersen the Agronomist for Orthman, we were privileged to be with these young folks for most of a day last week.  The day was filled with a great interactive session with the 2018 Top Vo-Ag School for the State of Nebraska in Polk, Nebraska and the students as well as the Vo-Ag advisor Tom Hoffman. Eyes were opened to a different and far-away world of Africa for these high school students of Polk.  Went to the field to show and explain the 11 acre corn study these students are involved with us at Orthman Manufacturing.  Explained how as a company, we at Orthman thoroughly invest time to educate, disseminate science to the farmer, aid farmers to seek out the reality of the technology of Strip-Till and its many benefits.  Questions that were asked were astute and well thought out and important.  The time with them was delightful, mind expanding, fulfilling and filled with promise that young African leaders will face the next 50 years with tenacity and toughness as well as with much growth potential as possible.

2019 Edition of the National Strip Till Conference

We at Orthman Manufacturing, Inc are getting ready for the 2019 edition of the NSTC in Peoria, IL – to hear the most up to data information, network with other like minded growers that utilize the Strip Tillage method of Conservation Tillage to raise row crops – COME!

 

Corn is finally taking off in the Western Corn Belt

We at Orthman have been out in the field collecting some very important data to verify with real numbers what the soil conditions are with Strip Till, especially in irrigated soils.  With the plentiful rains this spring which have been a Godsend for some and a deluge of too much for others across the Western into the Central and Eastern Corn Belt, the soils are exhibiting the issue of compaction and nitrogen either leached away from the upper root zone or way deep.

We are studying what soil resistance values are in the upper 15 inches to better express what we have seen for years as anecdotal information.  This time of the season is near perfect for running these tests.  As a soil scientist I have used soil penetrometers to identify where compaction exists and how thick those layers can be.  This season we are studying eight different soil textural types, three tillage methods; including No-Till or Direct Seeding, Conventional full width tillage and Strip-Till with the 1tRIPr (Orthman’s strip till implement).  With what we have collected so far the data is quite remarkable.  Our plans are to complete sampling and collection of data by the 21st of June.  So stay tuned but for sure visit our booth/stand at the 2019 Husker Harvest Days near Grand Island, Nebraska the second week of September.  We will be sharing it as a special program for visitors of the Orthman Manufacturing, Inc. stand.  The value of having this data should really tell growers some valuable clues on their tillage practices which influence, soil health, growth of crops and water management.

If I may, a suggestion is to check with your Territory Representative for Orthman by email, text or a phone call and chat with him about what we are discovering and what is this all about.  OR… communicate directly with me, Mike Petersen and I am glad to visit because this information has long term ramifications on your farm.  Even those of you that have used the No-Till method will be quite interested in what is happening below the surface.
