Summary

The Agricultural Management Dataset contains two variables which help
describe management regimes within agricultural lands of China. 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. The datasets were compiled
from multiple Chinese sources and all are at the county scale for
1990. The datasets which comprise this collection are listed below.

1) Agricultural Management
2) Crops
3) N-Deposition
4) Geography and Population
5) Land Use
6) Livestock
7) Soil Properties
