from soils with different fertilization histories,Plant Soil(2010)334:391407DOI10.1007/s11104-010-0390-6,七、结论,4.植物吸收的新鲜磷主要是受肥料特性和土壤有效磷状况影响。5.常规栽培的土壤上较高的微生物活性能不增加磷的利用效率。6.残余磷的回收最低的是biodyn土壤，最高的是confym土壤。7.间接同位素稀释技术对于评估植物对新鲜粪便中残留磷的吸收是有用的，但必须注意尽量增加磷相互作用。从新鲜粪便中吸收的磷可能由于高估了矿化作用，在确定土壤有机P时，标记植物吸收的有机磷源用间接方法。,Fresh
