Abstract: Based on the soil fert ility and fert ilizer effect of Beijing brown chao soil in the way of micro-trial of winter wheat-summer maizer continuous cropping, the annual grain yield and the ten-year soil organic matter change show that the crops yield, soil organic matter and soil fertility can be improved significantly by using N P K chemical fertilizers together with organic material under lower soil fertility. The effect can be greater with organic material increasing. The effect of using organic material is best, the second is using wheat straw. The effect of maizer straw combined with chemical fertilizers is similar to that of chemical fertilizers.

Key words: N, P, K, Organic material, Grain yield, Soil organic matter
