This paper studied the forms of organic phosphorus in topsoil by Bowman-Cole’s method. The results showed that phosphorous efficiencies of all treatments were increased compared with the control except N treatment. Phosphorous efficiency of M2NP treatment was the highest, increased by 5.59% compared with the control. The differences of total organic phosphorous of NP, M1, M1N, M1NP, M2N and M2NP were significant and respectively increased by 92.7%, 133.8%, 133.9%, 191.3%, 172.1% and 201.5% respectively compared with the control. Labile organic phosphorus increased most in organic phosphorous of all treatments except N treatment, increased by 205.1% - 420.5% compared with the control. Labile organic phosphorus of M2NP was increased by 420.5% compared with the control. Active organic phosphorus and moderately resistant organic phosphorus were the main components of Cinnamon organic phosphorus, accounting for 70% of the total organic phosphorus. Labile organic phosphorus and moderately resistant organic phosphorus contributed most to the available phosphorus.
