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.

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.

Providing Second Installment of the Strip Till Fact Sheets

Mike Petersen here back from a long trip to South Africa, the largest Southern Hemisphere farm show that gave us four beautiful sunny days, few clouds and great crowds coming by to visit, learn, make future decisions and actually place orders for equipment that we at Orthman manufacture as well as the associated John Deere planters.  To us that is exciting and good news, you might say well that is what happens doesn’t it?  Not always, for the most part in the States folks come to chat, kick tires and see if there is some pretty new paint.  For many of the African nation farmers that come, they are on a mission to educate themselves or move forward and get the lads at a specific stand to place the order.

Today as you read this blog I am offering the next in a lineup of Fact Sheets that provide you more information from the soils perspective what I have studied so much of my career looking at soils – Pore Space.  What is the big deal about pores?  Does it matter about size of pores and how many there could be in the upper soil horizons versus down lower in the soil profile?  Oh the answer is – Yes!  Oxygen movement up and down, carbon dioxide exchange, nitrogen in its gaseous forms, retention of water, release of water to the roots, how the microbiological lifeforms exist or not – oh the list goes on.  I offer this fact sheet to discuss some of the physical ramifications of pores.  Please see the attached article.

Precision Planting on the Strip – Not Only in the States But As Well in Africa

As we spoke to dozens of farmers in South Africa during the week of May 14-17, 2019, they reiterated that in a drier climate than much of the Corn Belt of the States, planting directly in the center of the strip created by the Strip Till machine was of extreme importance.  Their experiences shared were quite dramatic on how the crop grew to yield but how well the root expansion and depth made all the difference of having a crop for profit.  I asked the question partly knowing the answers – why?  A percentage of the growers across the Atlantic do not have RTK guidance and when they plant with varied spacing due to using the tram line methodology and getting off either due to contours in the rolling country or lack of guidance the yields dropped on the order of 8 to 15%.

Strip till and planter in one pass

Strip tilling and placing nutrients at 7 inches (180mm) deep hits the sweet spot.

Let us figure quickly on the average of what kind of cost that would be: on a 2000 hectare corn farm for example, that is a loss of 74.1 tons not produced.  Today’s price is $153+ per ton USD $11,340.00 USD or total in Rand for South Africa of $160,990.00.  A significant loss for the South African growers of maize.  Causes; in the Orange Free State and parts of Transvaal the soils can have a water table down at depths of  1 to 1.25 meters and having the root extend down through the loamy sand soils to that depth can insure a decent crop. Capillary action will fluctuate up enough so the roots drink freely to a depth of 700 mm and the corn does quite well.  Irrigation is spotty from ground water unless the farmer has developed small reservoirs and catch rainfall for overhead center pivots.  So considering what the prices of a RTK guidance system are in this day and age, we spoke of how quick the return on investment could be.

What does all this have to do with an American farmer?  As a friendly reminder to all you ladies and gentlemen growers, we at Orthman want to bring attention to the methods we use in the States having great value.  Farmers that are growing let us say 4000 acres of just corn at today’s prices, guidance to keep “on the mark or in the zone” if you will, the practice and electronic equipment really pays season after season.  As we visited more with the South African farmer and the subject went to fertilizers and placement – all those factors can be multiplied for yield if not Strip tilling and placing nutrients.

Coming back home to the States to the Western Corn Belt the message is clear, precision farming has definitely made a difference and will continue to do so.  We at Orthman Manufacturing carry a message that being “on the mark” has great return both for plant health and for return on investment for you, all across this great nation where corn is grown.

Contact us, at your Orthman dealer, via this site by your Territory Managers, myself – Mike Petersen, we would love to visit, email or take your call.

From Nampo – Biggest Farm Show in Southern Hemisphere

Greetings from Nampo-2019
After a long flight we are here to work with the guys chatting with growers from all over South Africa, Zambia, Namibia, Botswana and even China. Maize, sunflower, soya, sugar cane, both forage and grain sorghum are the crops that center our conversations. The big topic that the growers are concerned with is diesel fuel savings when they realize the what the Orthman 1tRIPr system is able to provide. A grower told us today that his savings was 55% compared to his conventional 4 pass system had been. That kind of savings is huge. Then the man said “Wait, my fertilizer has dropped by 45% and the 55% is the minimum savings, other farms it is a savings in diesel consumption by 75%.”
I ask what kind of savings when diesel fuel prices are high for your farm? Fewer passes, less wear’n tear, maintenance all are important. Stories similar are all week here at the show.

Orthman brings savings in many facets of what you do out on the farm. Time, labor, overhead, and soil erosion all are savings of great value. Come visit your Orthman to find out how the premium advanced conservation system works for you.

Let’s Talk About Fertilizer Placement in Reference to Early Season Growth

Continuing with sound information and data for those of you working to make the Strip-Till system you have the best and most productive or what you anticipate for the future.  I have loaded up another Spring  Fact Sheet to offer you more information on placement of fertility for the early to mid-season crop growth.  This fact sheet is the second in a line up of six we want to offer in 2019.

2019_Spring Fact Sheet_NutrPlacement

Nutrient placement continues to be a subject that has brought a lot of discussion in circles of the fertilizer industry as well as blogs from naming a couple; No-Tillers, Poor Dirt Farmers.  These groups are wanting to interact with you the grower and also provide information.  Please read this from us that we add to the conversation with first hand experience, field testing and interaction with some good people in the Fertilizer Industry.

Our view is to give you what we know to work in pre-plant nutrient placement as well as in-crop fertility.  Hang in there with us at Orthman as we offer more of these Fact Sheets into the days and weeks ahead.

Don’t forget we are on FaceBook too.

WE have developed some Agronomy Fact Sheets – Take A Look!
