Extraction Methods for Phosphorus and Their Relationship ...

Soil available has been measured using chemical extractants and ion-sink comprising of resin membranes and FeO coated filter papers or strips. This study compared the conventional chemical extractants such as Bray-1, Olsen, and Mehlich-3 etc with the ion-sink
