| Abstract: | This paper deals with the content of total P,avaiable-P, organic-P and inorganic-P, and characters of phosphate retention in major soil of rotation between tobacco and paddy roce in Hunan province. The correlation between component of the various inorganic -P and physical-chemical characters of soil, and the parameters (K, q_m and MBC) of phosphate retention by soil and content and ratio of the varous soil-P species were analysed. According to the fertility of soil phosphorus, the paper also proposes the amount of phosphate fertilizer applied. |
