摘要: The complex ecosystem of the rhizosphere is characterised by conditions quite different from bulk soil. One important reason release organic substances roots into rhizosphere. These exudates have influences on P mobilisation both in a direct and indirect way with help microbes, too. Therefore, method was elaborated to sample analyse root relation nutrition plants. water-soluble maize wheat plants depended at large scale. sugar carboxylic acid fractions changed their composition clearly. Under unsterile sugars had great effect mobilisation, more than acids some cases. Especially pentoses were very effective this way. Pentoses found stressed plants, particularly. close interrelation between performances microbiota regarding indicated.
