Predicting the capacity of soil to supply nitrogen is an ongoing challenge in organic farming. Organic farmers rely on the breakdown of organic matter through a microbially-driven process for crop nutrition instead of the application of synthetic fertilizers. One of the most frequent requests of organic farmers is to have access to better information about what is happening in their soil.

Impact: Availability of soil testing tools to account for nutrient mineralization from organic amendments.
