A 23 years-located experiment of wheat-corn rotation showed that long term application of animal manure combined with chemical fertilizer contributed greater to the contents of soil organic matter, total phosphorus, inorganic phosphorus and available phosphorus. Applying chemical fertilizer could increase soil organic matter, total phosphorus, inorganic phosphorus and available phosphorus contents, but the increment was lower than treatments animal manure and fallow. Compared with no fertilization, different fertilization treatment had its own distribution characteristics of soil organic matter, total phosphorus and available phosphorus in 0-100 cm soil layer.
一项长达23年的小麦-玉米轮作试验表明，长期施用有机肥与化肥相结合对土壤有机质、全磷、无机磷和有效磷含量的贡献更大。施用化肥可增加土壤有机质、全磷、无机磷和有效磷含量，但增幅低于有机肥处理和休闲处理。与不施肥相比，不同施肥处理在0-100厘米土层中土壤有机质、全磷和有效磷具有各自的分布特征。
