No evidence that Bacillus Thuringiensis genes and their products influence the susceptibility of corn residue to decomposition
The possibility that Bacillus thuringiensis (Bt) corn (Zea mays L.) residues resist decomposition compared to non-Bt residues would present direct (soil carbon turnover times) and indirect (changes in tillage practices) effects on carbon budgets in agricultural systems. We evaluated the relative decomposition of residue from two pairs of Bt and non-Bt corn hybrids from different seed ...

Corn morphology, mass, and grain yield as affected by early-season red: far-red light environments
The spatial arrangement among plants affects both vegetative and reproductive meristem development. More axillary meristems develop at lower plant densities, which are associated with relatively high red:far-red light ratios (R:FRs; 645:735 nm). However, little is known about the effect of R:FR on corn (Zea mays L.) productivity. We conducted field research to determine the effect of early-season ...

Benefits of vetch and rye cover crops to sweet corn under no-tillage
Leguminous cover crops (CCs) may reduce N fertilizer requirements by fixing N biologically and storing leftover N-fertilizer applied in the previous year. The objective of this study was to determine the contribution of CCs [rye (Secale cereal L.) and hairy vetch (Vicia villosa Roth)] on plant N nutrition and weed suppression to the following sweet corn (Zea mays L.). The CCs were planted in the ...

Effect of tillage and nitrogen rate on corn yield and nitrogen and phosphorus uptake in a corn-soybean rotation
Understanding tillage, N, and P interactions can contribute to improved N and P utilization and crop response. This study examined the interaction effects of tillage and N rate of two N sources on N and P uptake by corn (Zea mays L.). The study was conducted on Kenyon loam (fine loamy, mixed, mesic Typic Hapludolls) soil at the Iowa State University Northeast Research and Demonstration Farm near ...

A closer look at AMCO’s versatile Ditcher cutter heads
Standing water can kill crops in a hurry. That’s why a well-built drainage system is essential, especially if you: Live in a flat area or region with a lot of precipitation Plant corn, soybeans, cotton, rice, or other crops that are sensitive to waterlogging AMCO’s Vertical and Offset Rotary Ditchers are affordable tools that easily clean roadside ditches and reshape waterways. ...

Nitrogen contribution from red clover for corn following wheat in western Ohio
Inclusion of a winter legume cover crop into a crop rotation has been suggested as a method to provide a substantial portion of the N requirement of the following crop. While the benefits of winter cover crops such as reduced soil erosion, increased soil organic matter, and increased mulch cover have been well documented, the N contribution to the subsequent crop has shown to be variable. The ...

Six Late Harvest Tips: Don’t Leave yourself Out in the Cold
One of the big concerns this harvest has been the moisture and rain that delayed the planting of corn and soy. Now, as we get into colder and colder temperatures and the stretches of intense sunlight begin to dwindle, some farmers might wonder how they should change their approach to the season. I’m a research lead for The Climate Corporation at one of its research farms in South Dakota, ...

Conservation: It’s the right thing to do
A fable of six blind men and an elephant originated centuries ago somewhere on the Indian continent. In it the blind men try to identify an elephant by touching only one part. According to the fable each man came to a different conclusion as to what the elephant was. The parable illustrates that though opinions may vary, there’s some truth to be found in all of them. That’s the way ...

Improve Fall Nitrogen Practices
In most of the US, this fall was a wet one. Chances are, you didn’t get much of a chance to get fall anhydrous in the ground. Beacuse of this, we wanted our agronomist, Barry Anderson, to answer a few of our burning questions related to fall nitrogen application. You may have missed the window this year, but here are some tips to keep in mind for next year. 1. At what rate/ ...

Winter wheat and maize response to urea ammonium nitrate and a new urea formaldehyde polymer fertilizer
Slow release N fertilizers have potential to improve yield and nitrogen use efficiency (NUE) in winter wheat (Triticum aestivum L.) and maize (Zea mays L.). A slow release urea formaldehyde polymer (UFP) was compared with aqueous urea ammonium nitrate (UAN) [(NH2)2CO, NH4NO3] during a 2-yr field experiment in North Carolina. Crops were grown on Candor (sandy, siliceous, thermic Grossarenic ...

2020 Planting Prep: How Hydraulic Downforce Can Help
What conditions will you face during spring planting? With 2019’s extreme weather patterns, what comes next is anyone’s guess. That’s why it’s smart to prepare now. Planting into wet soil is completely different from planting into dry, compacted soil. Yet the fundamental challenge is the same—putting seeds in the right place, at the right time, and at the right ...

Emergence of polymer-coated corn and soybean influenced by tillage and sowing date
No tillage often delays soil warming and drying, thus sowing too early in the spring may compromise seed viability due to prolonged exposure to cold and wet soil in the northern Corn Belt. Coating seed with a temperature-activated polymer may circumvent the adverse effects of exposing seeds to cold and wet soil. Germination and emergence of noncoated and polymer-coated corn (Zea mays L.) and ...

Reduced soil tilling helps both soils and yields
Agriculture degrades over 24 million acres of fertile soil every year, raising concerns about meeting the rising global demand for food. But a simple farming practice born from the 1930's Dust Bowl could provide a solution, according to new Stanford research. The study, published Dec. 6 in Environmental Research Letters, shows that Midwest farmers who reduced how much they overturned the soil -- ...
