１０年水旱两季连作田土壤定位监测结果表明：有机肥配施化肥能提高土壤肥力及增产效益，长期单施化肥将导致土壤养分降低，肥力衰退，增产效益下降。
The monitoring results of 10-year paddy-field soil positioning in the two seasons showed that applying chemical fertilizers with organic fertilizer could improve soil fertility and increase yield. Applying chemical fertilizers for a long period of time would result in lower soil nutrients, lower fertility and lower yield.
