Abstract |
A study of nitrogen and phosphorus losses from Decatur silt loam soil was conducted over three cropping periods from 1969-1972. Experimental agronomy plots were seeded to cotton, corn, soybeans, and millet and compared with uncropped and unfertilized check plots. The effects of these crops on nitrogen losses - total nitrogen, nitrate-nitrogen, and ammonium-nitrogen (for 1971-1972 only) - and phosphorus losses were evaluated. Average total rainfall and losses of sediment and runoff were also determined. |
