Abstract/Contents:Presents a study conducted to evaluate the effect of surface cover, initial soil moisture content, and surface soil structure on the amount of fertilizer nitrogen lost in surface runoff water." Details methods and materials used in the study, stating that "eight experimental plots 12 feet wide by 35 feet long were established in a uniform area of established fescue sod. These plots were situated on a Zanesvill silt loam having a 13 per cent slope and a 'fragipan' layer at a depth of 24 to 34 inches. Half the plots were plowed to a depth of 6 inches in the spring and maintained in fallow by regualr cultivations...At the end of the growing season, ammonium nitrate pellets were broadcast uniformly over the surface of two of the sod plots and two of the fallow plots at a rate equivalent to 200 pounds of nitrogen per acre." Reports that "although the fallow plots consistently exhibited initially higher rates of runoff, the total runoff from the sod plots tended to equal that from the fallow plots after 5 inches of rain. The effect of a surface seal on the amount of runoff measured from the fallow plots was most pronounced during the first storm, when differences between surface conditions were greatest." Concludes that "the results of the experiment indicate that nitrogen losses can occur from ammonium nitrate pellets applied to the surface of either sod or fallow when conditions are such as to produce high rates of surface runoff. One might expect losses to be most severe when nitrogen fertilizers are applied to very wet soils or to fallow soils having a surface seal."
