“…The amount of nitrogen removed as nitrate by the tile system represented approximately 1.5 percent of the nitro gen added to the field. Johnston et al (1965) measured nitrate-nitrogen con centrations of tile effluent under various crops in the San Joaquín Valley of Cali fornia. Individual sample concentra tions ranged from 2 to 440 ppm.…”

Plant nutrient losses were measured in tile drainage effluent varied with season with N, drainage effiuent from three cropping systems P, K and Ca concentration tending to be on a Brookston clay soil over a 7-year period. lower in the spring. The amount of water that Highest losses of N, P and K occurred with flowed through the soil of a particular cropcoln and lowest with bluegrass sod. Addi-ping system was the predominant factor intions of N-P-K increased average losses of N, fluencing nutrient loss.

“…The latter was mostly in the soluble form. The California studies 22 showed an order of magnitude of less phosphorus in subsurface drainage waters than that found by Sylvester, as phosphorus quantities of only 0.02--0.48 Ib per acre per year were indicated.…”

This report discusses a survey by AWWA Task Group 2610 P of state sanitary engineers, which discovered that the major problem resulting from nutrients was eutrophication or a stimulation of the growth of algae and other aquatic plants in both flowing and impounded surface water supplies. The major water quality problems resulting from the heavy algal growths were taste, odors, and filter clogging. These problems were found in 56 percent of the total U.S. municipal surface water supplies.
