John Spargo, UMass Extension Soil Scientist and Director of the UMass Soil and Plant Tissue Testing Laboratory, shared his expertise with Nitrogen (N) dynamics in organic cropping systems at the Agriculture & Food Conference of Southeastern Massachusetts in February, 2013. Spargo discussed how to manage N to optimize crop quality and yield as well as how to minimize losses to the environment.
Spargo reminded growers that one of the fundamental principles of organic management is feeding soils so that soils can feed crops. Both nutrient deficits and excesses can be detrimental to crop health and yields. [Read more here.]
