Summary
Abstract: (from Project Abstract)
Problem: the objective of this research is to determine and contrast
soil nitrogen, soil carbon, and soil phosphorus accumulation and
availability under common farming systems in the Mid-Atlantic states.
These systems consist of long term cropping patterns ranging from
continuous corn through numerous rotations to continuous grass.
Nitrogen is being supplied as animal ... View entire text
