China County Data Collection, Agricultural Management Dataset
Listed in NASA Earthdata CMR
The Agricultural Management Dataset contains two variables which help describe management regimes within agricultural lands of China.
Description
The first variable, Irrigation Index, reports the fraction of cropland in a county which is under irrigation, excluding rice paddies. The Second variable, Nitrogen Fertilizer, reports the tonnes of nitrogen fertilizer applied in the county per year.
See the references for the sources of these data. China County Data collection contains seven datasets which were compiled in the early 1990s for use as inputs to the DNDC (Denitrification-Decomposition) model at UNH. DNDC is a computer simulation model for predicting carbon (C) and nitrogen (N) biogeochemistry in agricultural ecosystems.
