Abstract: Phosphorus at home and abroad for the long-term positioning was located in most of the trial on fertilization, and the Research Of the effects of tillage was not many In this paper the long-term 16-year Albic soil has been studied, Test results show that effects of different tillage on total phosphorus and available phosphorus is far less than fertilization.Effects of different tillage on phosphorus in soil is interior to fertiliza- tion.No-tillage is more beneficial to accumulate soil total phosphorus than deep and conservation tillage, but isn’t beneficial to accumulate soil available phosphorus,of the phosphorus forms of all are increased, except for LOP; In the treatment of deep and conservation tillage, apart from Ca2-P, the variation tendency of other forms is same. Therefore, we can improve the situation of soil phosphorus fertilizer by taking the measures of different farming in addition to fertilization.
