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