Field and Statistical Modeling Study to Estimate Irrigation Water Use atBenchmark Farms Study Sites in Southwestern Georgia, 1995-96

摘要

This report presents irrigation data collected during 1995-96 in the study areaand describes results of the statistical analysis. This report also describes the method(s) developed for the Benchmark Farms Study to monitor and collected site-specific irrigation water use in southwestern Georgia. A five-component statistical model developed to estimate total irrigation water use in the study area in 1996 is also presented. The five model components are ordered in a recursive structure-whether-to-irrigate, acres irrigated, crop selected, seasonal-irrigation scheduling, and the irrigation applied. Comparisons of model results to sampled data and to other methods of estimation also are included. The study area consists of 32 counties in southwestern Georgia.
