THE ROLE OF COTRIC ACID AS A PHOSPHORUS MOBILIZATION MECHANISM IN HIGHLY P-FIXING SOILS

THE ROLE OF COTRIC ACID AS A PHOSPHORUS MOBILIZATION MECHANISM IN HIGHLY P-FIXING SOILS

Exudation of low molecular weight carboxylates is an important phosphorus (P) acquisition strategy for plants in strongly P-fixing soils. The effect of citrate exudation on P availability was studied in five acid soils with a large organic matter content and a low available P pool. The amount of mol...
