Rotation and Nitrogen Fertilization Effects on Changes in Soil Carbon and Nitrogen
Entry ID: USDA0098

[ Update this Record ]

Summary
Abstract: The dataset consists of data resulting from an experimental
study involving seven cropping systems (three monoculture, two
2-year, and two 4-year rotations) with three rates of N
fertilizer. Data includes dry matter samples and soil samples
with resulting analyses to determine total C and N content. The
dataset was used to evaluate different treatment and crop
rotation combinations and their ... View entire text
