Kansas State University researchers received a $2 million award from the National Science Foundation to develop sensors that can more accurately detect nutrients, chemical compounds, soil microbiomes and greenhouse gases in soil.

How Nitrogen Fertilizers React with the Soil

September 9, 2024

Anhydrous ammonia (82% N) is applied as a gas from high pressure tanks through tubes and anhydrous knifes that inject ammonia (NH3+) six to eight inches below the surface to minimize (NH3+) escape into the air.

How Controlled Release Nitrogen Affects Strip-Cropped Corn

August 27, 2024

Research on corn-soybean strip-cropping has demonstrated higher yields on the edge rows of corn and reduced yield on the edge rows of soybeans.

A benefit of legumes is that they can mine nitrogen, phosphorus, and potash from the subsoil. Frame said a goal of the research is to discover if those nutrients from the cover crop can be used by the cash crop following the cover crop.

How Cover Crop Species & Termination Time Affect N Release

While later cover crop termination in the spring can allow for more biomass accumulation, such later termination can change the C-to-N composition of the plants impacting residue decomposition. Therefore, identifying the best time for cover crop termination to provide optimal N cycling benefits can help farmers make decisions about cover crop management.

Growing Nitrogen with Legume Cover Crops

Nitrogen is an essential nutrient for plant growth, but price fluctuations of fertilizers leave farmers looking for alternative solutions. Planting legumes as a cover crop can increase soil nitrogen and perhaps even reduce reliance on fertilizers.
