Download or read book Genetic Manipulation of Crop Plants to Enhance Integrated Nutrient Management in Cropping Systems-1. Phosphorus written by C. Johansen and published by . This book was released on 1995 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: This WOrkshop forms part of an overall endeavor to establish a global consortium of researchers focusing their efforts on improving the ability of crop plants to acquire phosphorus, particularly through sources from which it is only sparingly avaiable. These sources include bound forms of soil phosphorus and such fertilizers or amendments as rock phosphate. This volume explains the overall procedures followed, presents the formal papers prepared for the form of a preliminary draft proposal for global project. A background paper covers the possibilities of favorably manipulating phosphorus acquisition, shich include moditying root absorption area by improving rooting caracteristics or mycorrhizal associations, manipulating ion absorption mechanisms, and modifying the rhizosphere throug root exudations of effects of microorganisms.
