摘要

A 5-year study was conducted to evaluate the effect of high-rate pig manure (HM) applications, in addition to the normal inorganic fertilizer (IF), on water quality, soil fertility, and crop growth on a silty loam (Typic Fragiaquept). Two crops werefertilized (IF) according to N requirement: silage maize was given 180 kg/ha, and a Phleum pratense + Trifolium repens forage mixture 55 kg/ha. In addition, HM was applied at twice these rates to each crop on separate plots in three ways: all in the autumn, all in the spring, or split equally between these two seasons. Control plots for each crop received only IF. In contrast to forage, relatively more total N1, NH4-N, and NO3-N was lost in runoff and drainage from maize when HM was applied in additionto IF, the degree of difference depending on the year. Although there were no autumn-spring or split-whole application differences for total N or NO3-N for either crop, there was frequently much more NH4-N lost from autumn applications to maize (as compared to spring), the effect being year dependent. Pig manure in addition to IF generally did not affect P lost in drainage and runoff consistently. However, autumn application often produced higher runoff P losses for both crops. Whole (vs split) applications sometimes increased runoff P for both crops. Drainage P was little affected except for a decrease sometimes when HM was added. In comparison to forage, there was much more NO3-N in the top two layers of the maize soil (0-200 and 200-400 mm). Therewas no treatment effect on soil P. Yield increases were much higher for the forage mixture than for maize. Applying high rates of HM in addition to IF caused water pollution by N and P and NO3-N accumulation in soil, but generally to a greater degree formaize than for forage for the same level of over-fertilization. Treatment effects were often crop and year dependent.
