Modeling of plant mineral uptake based on biophysical and chemical activity of the rhizosphere

The plant mineral nutrition results mainly from the functioning of the rhizosphere and numerous synthetic models for predicting the mineral uptake by plants have been consequently built around local models of bio-physic-chemical functioning of rhizosphere. This paper has as one's aim to do a review of the topic. II presents at first the evolution of ideas concerning the functioning of rhizosphere and shows how the prime models, which are originated, have been used for predicting the mineral uptake by the whole plant. The critical analysis of these models and of their limits as predicting toot makes it possible to bring out the great ways of research followed now for modelling the mineral nutrition of plants.
