The series Rhizosphere Biology emphasizes the different aspects of the rhizosphere, the narrow region of soil or substrate that is directly influenced by plant root secretions. A major increase in agricultural productivity to meet the growing food demands of the human population is imperative to survive in the future. Along with methods of crop improvement, an understanding of rhizosphere biology, and the ways to manipulate it, could be an innovative strategy to deal with this demand of increasing productivity. This series provides comprehensive information for researchers and encompasses all aspects of the field of rhizosphere biology. It comprises topics ranging from classical studies to the most advanced application being done in the field. The rhizosphere is a dynamic environment, and a series of processes take place to create a congenial environment for plants to grow and survive. There are factors that might hamper the growth of plants, resulting in productivity loss, but the mechanisms are not very clear. Understanding the rhizosphere is needed in order to create opportunities for researchers to come up with robust strategies to exploit the rhizosphere for sustainable agriculture. There are titles already available in the market in the broad area of rhizosphere biology but there is a major lack of information as to the functions and future applications of this field. These titles have not given all the up-to-date information required by today's researchers and this series aims to fill those gaps.
