Description / Table of Contents:
Crops as Enhancers of Nutrient Use examines the various plant and soil factors that contribute to nutrient use efficiency of plants. It attempts to address policies regarding Low Input Sustainable Agriculture (LISA), conservation-oriented cropping systems, and reductions in environmental contaminants. It also presents longer-term remedies to some of the inherent problems of high volume applications of expensive fertilizer nutrients. This book emphasizes plant-soil interaction, particularly, nutritional interactions involving rhizosphere, microbes, and stress on the root system. Stress factors include moisture and low and high pH. The book also covers the genetic and physiological response of plant to nutrients at the cellular level, on a whole-plant basis, and when subjected to stress. This book will contribute to the development of a more cost-effective and judicious nutrient usage of major crops.
