The result showed that soil basis fertility had slowly decreased on the condition of continual no fertilizer applied by time going with the analysis of five cropland continual orientation inspect in qunzhou city from 1999 to 2003. Contrast to inspect before, organic matter and content of total N had increased a litter as well as alkali N content decreased in cropland soil of inspect spot fertilizer area. The range of available P was high in the state of surplus accumulation as well as available K content decreased remarkably in the state of low content show that soil nutrient balance, N, P content was surplus as K content was absent seriously. The structure of fertilizer application was unbalance, organic fertilizer application decreased as fertilizer application increased step year by step year, the ratio of N, P, K was unbalance.
