Abstract

It is a well-known fact that the total phosphorus content of a soil is not a measure of the amount of available phosphorous. Some soils that contain a low total phosphorus content may be supplied with sufficient available phosphorus for present crop needs. On the other hand, some soils that contain a relatively high total phosphorus content may be deficient in available phosphorus.
