The relationship between labile phosphate and bray P1 extractable phosphate

The relationship between Bray P1 extractable phosphate and labile phosphate was studied for some recently published data from soils of northern New South Wales. The relationship between extractable phosphate and labile phosphate is more complex than might be assumed, and depends upon the sorption characteristics of the soil. It is therefore not possible to accurately estimate labile phosphate simply from Bray P1 extractable phosphate.
