Continuous Dryland Cropping in the Great Plains: What Are the Limits?

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...

Searching for synergism in dryland cropping systems in the central Great Plains

Previously published research reported a “synergistic effect” of corn (Zea mays L.) on winter wheat (Triticum aestivum L.) and proso millet (Panicum miliaceum L.) water use efficiency (WUE) when corn (C) was the preceding crop for dryland cropping systems in the central Great Plains, i.e., less water was required to grow a unit of wheat (W) or proso millet (M) when corn was the preceding crop. ...

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 ...
