WebAdsorption of acid phosphatase on goethite, kaolinite and two colloids from the soils in central and south China in the presence of organic acids and phosphate was studied. With the increase of anion concentration, the ability in decreasing enzyme adsorption followed the sequence: phosphate&gt;tartrate&gt;oxalate&gt;acetate. WebAdsorption and Desorption Adsorption is the chemical binding of plant available P to soil particles, which makes it unavailable to plants. Desorption is the release of adsorbed P from its bound state into the soil solution. Adsorption (or “fixing” as it is sometimes called) occurs quickly whereas desorption is usually a slow process.
