Sustainable Management of Soil Resources in the Humid Tropics

Więcej o książce

Misuse of the soil and inappropriate agricultural systems are causing serious degradation of the humid tropical eco-region and perpetuating food shortages, malnutrition, and poor standards of living.What is needed are sustainable agricultural systems that can satisfy human needs while maintaining soil fertility and the integrity of the environment. This publication makes available research information on scientifically proven methods of deforestation for conversion to agricultural land use, and soil and crop management systems that allow for the sustained use of soil and water resources in the humid tropics. The reader will find numerous examples of appropriate techniques with explanations of their impacts on production, soil quality, and the environment. Information is provided on the characteristics of an improved farming system; new land development; run-off management and erosion control; nutrient management; and, in the final section, research and development priorities are outlined.This compendium will be of particular use and interest to planners, practitioners, extension agents, and others involved in humid tropical soil resource management.
