Abstract

To investigate the nitrate leaching risk of three red soils in subtropical China, this study conducted seven different manure treatments, namely, 0 (CK), 50 (F50), 100 (F100), 200 (F200), 400 (F400), 800 (F800), 1600 kg N hm-2 (F1600) with half of local conventional chemical fertilizers (N: 50 kg hm-2, P: 25 kg hm-2; K: 50 kg hm-2) in a two-year pot experiment. The results showed nitrate leaching was significant affected by soil type and manure application rate. The leaching risk in the red soils decreased in the follows: granite > sandstone > red clay. The nitrate leaching risk to groundwater environment was enhanced when manure was applied at 206 kg N hm-2 for red clay soil, 113 kg N hm-2 for sandstone soil and 97 kg N hm-2 for granite soil.
