Indonesia has extensive areas of post extraction secondary forests and degraded lands arising from intensive exploitation of forest resources in recent decades. Using the area of forests resulting from selective logging practices as an estimate, in year 2000, post extraction secondary forests covered about 23 million ha, or about 55% of the total concession area.

In tropical forests, RIL has been tested and appliedon a small scale for more than a decade. Various timber-producing countries in Asia and the Pacific have recognized its potential for advancing sustainable forest management. Yet many questions remain and the lack of sound and appropriate information continues to impede the widespread application of RIL. This book helps fill that critical information gap.

Claims of sustainability are virtually impossible to prove but enough is known about tropical forest ecology and silviculture to protect ecosystem functions and maintain biodiversity while still deriving financial profits from logging. Rapid improvements in long-term forest production will derive from better planning of harvesting operations and stand improvement treatments. Lack of good management plans generally results in logging practices that destroy natural regeneration and increase forest susceptibility to soil loss, wildfires, and weed infestations.

A Land management practice has many forms and the focus of this research is on

traditional land management practices. The main objective of this study was to assess the

role of traditional land management practices in improving cropland productivity in the

study area. The study was mainly focused on describing the soil fertility status between

lands with and without traditional land management practices.12 Soil sample was taken

from farmland with four and above practices and another 12 soil sample from farmland
