Title: Effects of Phosphorous Bacteria Fertilizer on Phosphorus Validity of Calcareous Soil
Abstract: The soybean experiment was conducted in pot with calcareous soil in north China.By the design method of complete random block.The result had shown that its function was obviously different in different phosphorus form soils.The Psolubilizing ability was low in the poor available phosphate soil.Phosphorus bacteria fertilizer couldn't improve the content of available phosphate in rich available phosphate soil.But the P-solubilizing ability was best in rich sparingly soluble phosphate soil.As were shown by the followings: Phosphorus bacteria fertilizer could decrease the content of sparingly soluble Ca_(10)-P and alleviate-soluble Ca_8-P,and increase the content of Ca_2-P and Al-P inthe poor available phosphate soil and in the rich sparingly soluble phosphate soil.So it increased the content of soil available phosphate.But in the rich available phosphatesoil wheather using phosphorus bacteria fertilizer or not had little effect to various inorganic phosphorus forms.
