Mineralization of Organic Nitrogen in Soil Under Plow and No-tillage Management

Entry ID: USDA.ARS.NRI.ECL.MinOrgN

[ Update this Record ]

Summary

Abstract: (adapted from Project summary)

Problem: Cultivation of soils has caused large decreases in content
of soil organic matter and this has raised concerns about sustainble
use of agricultural lands under the intense tillage operations used in
conventional management systems. Work was performed to investigate the
effect of soil structure disturbance on the release of active and
protected organic N in ...
