Although the ways in which farmers access irrigation services in areas that rely on groundwater have changed over the past decade, little empirical work has measured the impact of these changes. This is surprising given the potential effects--both positive and negative. In this paper we explore...

The flux of evaporation, transpiration and deep percolation play an important role in agricultural water management. In this study, oxygen-18 was used to determine the three fluxes in the summer corn and winter wheat field under existing irrigation pattern in Shanxi Province, China....

Mechanisms of crop root water uptake play an important role in agricultural water management. In this study, stable isotopes were used to understand root water uptake patterns for the main crops (summer corn and cotton) in Shanxi Province, China. Precipitation, irrigation water, soil water,...
