Abstract:Soil column is used to study the characteristics of the movement of phosphate in uprightness direction in brown soil which is in one year rainfall condition. The result shows that the significant correlation coefficient of fertilization quantity and available P,retainable P is 0. 991 41,0. 997 74;the better correlation coefficient of soluble P,Al-P and available P is 0. 972,0. 926. The 25 mg/kg fertilizer P in combination with 2 500 mg/kg chicken feces can reduce the eluviate rate,and can improve Olsen-P of the soil markedly,be equal to 50 mg/kg fertilizer P singly;the fertilizer P in combination with straw have little influence of available P,but can reduce the movement of phosphorous.
