Water soluble phosphates when added to soils are very rapidly converted to insoluble forms, or "fixed" in the soil. Phosphate fixation, as a rule, results in decrease in the avaliability of the applied phosphate in the growing plant, so that the amount utilized by crop seldom exceeds 40-50% of that applied. So many cases as little as 10-25% of the applied phosphate is utilized by the crop. As a result of phosphate fixation, continued manuring and croping of a soil will, in general, gradually increase the amount of soil phosphurus unless some external factor, such as soil erosion, interferes. |
