Soil Water Intake Rates and Surface Irrigation System Characteristics by Soil Series in Southeastern Idaho

摘要

Seven major soil series of irrigated agricultural land in southeastern Idaho, ranging from silt loam to gravelly loam in texture, were evaluated to obtain soil water intake rates. Three crops (hay, grain, and potatoes) were selected for the study, and soil survey maps from the local Soil Conservation Service were used to locate each area soil series. Since it was difficult to select representative sampling sites in a given field, it was necessary to test several different sites to obtain average results. Irrigation practices evaluated on two furrow fields from data obtained in the study revealed that improved water management practices are needed on both fields to obtain higher application efficiencies.
