Abstract
A study of three sands in sterilized columns revealed that, with the exception of nitrate, the mineral fraction of these soils is moderately resistant to leaching of several common nitrogen carriers. It is proposed that this resistance to leaching provides an effective buffer against increased nutrient loadings of ground water by heavy applications of manufactured fertilizer. A principal conclusion of the study is that accelerated lake eutrophication is taking place because surface waters are being nourished at levels above that normally provided by ground water seepage. It is believed that much of this hypernourishment is brought about by direct flushing of large amounts of material of biological origin into the lake basins by storm water. (Author)
