Nitrogen
Residue might hamper uptake, surface cover slows soil warming and most cover crops raise the carbon penalty. Farm Journal Field Agronomist Ken Ferrie shares timing and placement tips for phosphorus, sulfur and nitrogen.
Two new studies from Locus Ag and Pivot Bio found the use of biological products consistently increased yields in a variety of crops across a range of growing conditions.
Nitricity is on a quest to reduce global greenhouse gas emissions via its innovative natural liquid fertilizer manufacturing process. The technology represents a major disruption to the global fertilizer market.
Experts are watching global dynamics to understand the input market’s longer-term outlook in the U.S. Among their top concerns are geopolitics, weather and low supply.
ICIS senior fertilizer editor Mark Milam shares that while the fertilizer market appears to be in good shape at the moment, there are a couple of important trends moving forward this spring.
The survey uses records from ag retailers to measure the use of cover crops, nutrient management and conservation tillage and no-till by Iowa growers.
Once you balance fertility and pH in the soil profile, and adjust to making small, more frequent lime applications, you probably won’t need to mix fertilizer into the soil, says Ken Ferrie, Farm Journal field agronomist.
Red clover can fix nitrogen, suppress weeds and improve crop yields. Based on test plot research in Illinois, a good stand of red clover can provide between 50 and 100 pounds of nitrogen per acre.
“Nitrogen is a farmer’s biggest investment in corn production, so we need to do everything we can to protect it,” said Dan Quinn, assistant professor of agronomy at Purdue University.
If you value the benefits starter fertilizer offers, you might like the performance of a starter fertilizer relay system even more. Farm Journal Test Plot data show a relay system + 2x2 placement = $36 per acre ROI.
