Desert plant communities are among the most sensitive to changes in soil water conditions. In areas with shallow aquifers, it is important to understand both the effects of groundwater alterations on vegetation and how changes in surface-soil water affect plant water uptake. Studies in arid environments have evaluated the effect...

China's Minqin Oasis once welcomed traders along the ancient Silk Road with rivers, lakes, and lush forests, yet today the region's farmland and grassland are increasingly being engulfed by the sands of the Gobi Desert. The severity of this incremental catastrophe for a declining population of 300,000 residents has brought...
Flexible cropping systems allow for an opportunistic change in an established rotation. Plant-available soil water is the most reliable indicator of potential yield.
It is known that soil biota affects water dynamics through various complex mechanisms. The impact on retention by soil biota are due to a combination of changes to pore geometry, pore clogging by biofilms, biofilms that serve to connect thin water films across many pores as the soil dries, and...

Extensive areas of eastern Oregon, eastern Washington, and Idaho are well suited to dryland production of small grains and legumes. Commonly, over this area, winter wheat is planted in rotation with either annual legumes or summer fallow.
