Residue Management to Improve Precipitation Storage and Water Use Efficiency.

Successful dryland crop production in semiarid environments is dependent upon efficient storage of precipitation and use of stored soil water supplies. The objectives of this presentation are to: 1. Summarize information regarding the effects of time of year; environmental parameters; residue orientation, cover, and mass; soil type and texture; and tillage on precipitation storage efficiency, and 2. Summarize information regarding the factors influencing precipitation use efficiency.
