Available in PDF, EPUB and Kindle. Book excerpt: Three methods to remove nitrates from the agricultural drainage water from the San Luis Service Area in California were investigated. One method was a theoretical evaluation of nitrate removal by algae during the transport of the drainage water in the San Luis Canal or during storage in the Kesterson Reservoir. The other methods were designed to promote anaerobic bacterial denitrification in a continuous flow of drainage water. One method used barley straw and the other water grass grown in shallow ponds as the carbon energy source. Under optimum conditions both of these last two methods reduced the nitrate -N concentration of the drainage water from a maximum of about 30 mg/l to less than 2 mg /l. The cost of nitrogen removal by the shallow grass plot systems, the most economical and feasible method investigated, was estimated.

Available in PDF, EPUB and Kindle. Book excerpt: The report is one of a series which presents the findings of intensive interagency investigations of practical means to control the nitrate concentration in subsurface agricultural waste water prior to its discharge into other water on such areas as the San Joaquin Valley. As a result of the application of large quantities of water to relatively slowly permeable stratified soils, the west side of the San Joaquin Valley now has large areas with groundwater at rootzone depths. Wherever subsurface drains have been installed to control this groundwater, the drainage effluent has had high nitrate concentrations. Large quantities of inorganic nitrogen fertilizers are applied annually and the assumption prevails that fertilizer is the major source of nitrates in the drainage water. The study was designed to evaluate this assumption and to derive, if possible, practical answers regarding the role of on-farm practices in controlling nitrate out-put from the agricultural lands. Examined are the nitrogen budget and methods for reducing the quantity of nitrates in the drainage effluent by modifications in type or use of fertilizers, practicespractives, or drainage techniques.
