Amelioration of Soil by Trees

A review of current concept and practices

image of Amelioration of Soil by Trees
The utilisation of marginal and degraded lands, often associated with regions of high population densities, has high international priority for food and fuel production, erosion control and conservation. It is commonly believed that the enhancement of fertility of these soils can be achieved by the use of trees, particularly by manipulation of the associated coil biological processes. In this volume, this belief is subject to initial scrutiny and various proposals are made for the research to investigate the links between trees and soil fertility.



This volume represents the collection of papers presented at the Commonwealth Science Council’s Agroforestry meeting in India in March 1986 for Africa and Asia.

Amelioration of Soil by Trees - the Way Forward

Tropical soils vary greatly in type and productivity. Geologically recent soils of volcanic or sedimentary origin are often very fertile. Those derived from older igneous rock and are heavily leached, are acidic and have a low moisture and nutrient-holding capacity.
