Conference paper

Summary

This chapter discusses the processes in the rhizosphere that are determined by exudates from roots and that in turn affect the availability of phosphorus to plants. These include control of rhizosphere pH, exudation of organic acids and root phosphatases. Possibilities for manipulating these processes in order to improve phosphorus acquisition in agricultural plants are discussed in the context of the phosphorus cycle in agriculture.

Key words

Cation excess Citrate Malate Organic acids Phosphatase Phosphorus acquisition Phosphorus nutrition Phytase Phytate Proteoid roots Rhizosphere Rhizosphere pH Root exudates Soil phosphorus
