A water, nutrient and sediment budget for an Irrigated Farm in the Boise Valley Item Info

During the summers of 1971 and 1972 the Agricultural Engineering and Soils Departments of the University of Idaho conducted a study on a gravity irrigated farm in the Boise Valley. The purpose of this study was to determine the quantities of total solids and selected nutrient materials that were lost from the farm as a result of irrigation. In order to obtain the necessary data, measuring devices were installed in all ditches and equipped with stage recorders to obtain a continuous record of the flows entering and leaving the farm. Water samples of the head- and tailwater were collected during each irrigation set. Samples of the ground water were periodically collected from ten twelve-foot piezometers located on the farm. During 1972, four sets of solution samplers were installed in each field. Samples of the soil solution at various depths were collected from these samplers after each irrigation. All samples were quick-frozen and sent t o the laboratory for analysis. Each sample was analyzed for nitrate-nitrogen, ammonia, organic nitrogen, two forms of phosphorus and total solids. APHA Standard Methods and FWCA Standard methods were employed in making these analyses.
