ROLE OF ROOT DERIVED ORGANIC-ACIDS IN THE MOBILIZATION OF NUTRIENTS FROM THE RHIZOSPHERE

Abstract:

The role of organic acids in the mobilization of plant nutrients from the rhizosphere was assessed in seven contrasting soil types. The results indicated that malate was poor at mobilizing micronutrients from all the test soils, whilst citrate was capable of mobilizing significant quantities. Citrate was also capable of mobilizing P from one soil which possessed a large Ca-P fraction. This mobilization of P was due to both the complexing action of the citrate anion and due to the dissolution ...
