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.
With Palmer amaranth becoming more herbicide-resistant, producers are pushing to find new ways to control it, such as using a rye cover crop to suppress it.
A University of Kentucky study titled "Productivity benefits of cereal-legume cover crop mixtures under variable soil nitrogen and termination times" suggests that mixing cover crops is a beneficial strategy for modern agriculture.
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.
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.
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.

As Corn Belt states seek ways to curb nitrogen flow from farms into the Gulf of Mexico, new University of Illinois research adds evidence for winter cover crops as an important part of the solution.
To keep nitrogen where it can do the most good, a team of ARS scientists is developing new techniques for cover crop breeders. Their goal: to help the breeders identify plants whose extended underground root systems (known as the rhizosphere) are most effective at keeping nitrogen in the soil.
