The organic matter in soil contains a small but fairly uniform proportion of phosphate.
土壤有机质中含有少量的磷酸盐,且其比例始终不变。
2
Organic acids can improve soil phosphorus availability by affecting the inorganic phosphorus fraction and mobilizing soil sparingly soluble phosphate.
有机酸通过影响土壤中无机磷组分,促进难溶性磷酸盐溶解,从而提高土壤磷的有效性。

It was studied that the effect of different kinds of organic acids and their concentrations on the soilphosphate absorbing capacities by way of isothermal absorption in the brown soil.
