Runoff and Erosion Estimates for Great Plains Dryland Agroecosystems

Water is the most production limiting factor for dryland cropping systems in semiarid Great Plains environments. Evaporation is responsible for the greatest amount of water loss and management practices such as notill have been adopted to reduce evaporative losses. Less is known about the magnitude of water loss due to runoff. An objective of this study is to estimate an expected range in rainf...

Efficient Water Use in Dryland Cropping Systems in the Great Plains

those methods as they have been used from the Canadian Prairie Provinces to the southern Great Plains of Successful dryland crop production in the semiarid Great Plains the United States and the resultant effects on system of North America must make efficient use of precipitation that is often limited and erratic in spatial and temporal distribution. The purpose WUE. Additionally, differences i...

Management of Dryland Cropping Systems in the U.S. Great Plains: Effects on Soil Organic Carbon

The expansion and intensification of agroecosystems worldwide has significantly affected the environment at multiple spatial scales (Matson et al., 1997). Agroecosystem effects on atmospheric constituents have altered local, regional, and global environmental quality through windblown soil (Zhang et al., 2001) and emission of particulate matter, reactive N (e.g., NH3 and NOx), volatile organic ...
