Research Applications
Cover crops and mulches are used to improve soil physical, chemical and biological characteristics. PRS® Probes have been used to document the impacts of these practices on soil nutrient supply.
Examples
- Residues from a buckwheat (Fagopyrumesculentum) green manure crop grown with phosphate rock influence bioavailability of soil phosphorus.
- The reduction of plant-available nitrogen by cover crop mulches and subsequent effects on soybean performance and weed interference.
- Release of available nitrogen after incorporation of a legume cover crop in Concord grape.
- Integrated management of inorganic and organic nitrogen and efficiency in potato systems.
