Interpretive Summary:

Technical Abstract: 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. Data are presented from two distinctly different rainfall regimes: the central Great Plains with a predominantly summer precipitation pattern and the inland Pacific Northwest with a predominantly winter precipitation pattern.
