The amount of Ca8-P in soil with CRMP treatments was lower than that of CMP treatments. The changes of the amount of Al-P, O-P, Fe-P and Ca10-P in soil were neglectable during the course of experiment.3. The shoot and root weight of sorghum increased through application of phosphorus, in addition, The increase of sorghum shoot and root weight was greater than that of common monoammonium phosphate due to the slow release of nutrients from CRMP. The accumulative uptake of phosphorus in shoot and root with CRMP treatment was greater than that with CMP treatment in low (75 mg P2O5/kg soil ) and high（150mg P2O5/kg soil）rates, especially on middle stage, and in high phosphorus rate, this advantage was more obvious than that in low phosphorus rate.

No evident regularity was found in the depth from 15 to 30 cm. There was an obvious accumulation of OM and TN in the top 30 cm of the fallowed soils, of which the accumulation of OM was faster than that of TN and there was more accumulation in no-tillage compared to tillage. Soils applied with inorganic and organic fertilizers had much more OM and TN at 0～5 cm and 5～15 cm depth than soils applied with only inorganic fertilizers and soils without fertilization. However, OM and TN in these treatments were less than that in fallow treatment. No significant differences in OM and TN contents were found between fertilization treatments. Only in the 5 cm of top soils, OM and TN of the soils treated with only inorganic fertilizers were more than that of CK.
