Response to fertilizers of pinegrass dominated vegetation on Gray Wooded soils was tested in pot and field trials. Ammonium nitrate applied at 100 and 200 kg N/ha increased the yield, nutritive value, and palatability of pinegrass; this increase was accentuated when S in the form of gypsum was applied with N. Response to P, K, and a solution of micro nutrients was negligible. Most of the applied S and all of the applied N were depleted from the upper root zone by the end of the second growing season. At the higher rates of application, only 14% of the N was recovered by pinegrass. This value was even smaller at the lower rates of application. Sulfur considerably improved the ability of pinegrass to respond to N fertilization and 23% of the N was recovered when 100 Kg S/ha was applied with the N. Soils were analyzed for NO3-N, SO4-S, field moisture and organic C. These two elements and organic C were found to be mainly concentrated near the soil surface, which experienced the greatest fluctuation in moisture content.Type
