slope. The soil erosion decreases in different way of cropped land. Recent years have seen a number of changes in the management of forests. Narrow based terrace: It consists of making a number of narrow based ridges or bunds at a distance of 1m to 2m across the slope of the land at suitable intervals in high rainfall areas? Finally, declines in soil health occur rapidly, often most dramatically in the first 10 years following conversion of undisturbed land to agriculture, but improvements to soil quality take place slowly and at greater cost than maintaining a good soil in top condition. For jfrm to represent participatory forest resource management emphasis on regenerating timber through community protection needs to be shifted to developing sustainable alternatives for meeting diverse forest produce needs of members of community institutions. We rarely even think of it as a natural resource that needs to be conserved, a part of the natural wealth that needs to be preserved. The adverse effect of soil erosion is not confined only to decrease in soil depth but ultimately to the loss loss of organic matter and plant nutrients and consequently to degradation of soil physical properties and crop yield decline ( Young 1984). Afforestation is the best means to check the soil erosion. It is a comprehensive prospective work programme to bring 33 area under forest/tree cover in a phased manner within 2020. Lutz and Chandler (1946) cited the following points in support of vegetational check erosion as follows?

Trends in all the soil-quality indicators showed considerable improvement between 19The majority of the cultivated land in Canada is in the very low risk class for erosion. When villagers dependent of forests, have initiated forest protection on their own, the challenge for forest departments is of facilitating the process which implies adapting the official jfrm frameworks to enable forest departments to participate in villagers initiatives. There are many cases of communities protecting natural forests either on their own initiative or with the encouragement of forest department. Here are some ways to conserve soil. Terracing A terrace is an embankment of ridge of earth constructed across the slope to control run off and to minimize soil erosion. Soil Profile, a soil profile is the side view of soil, from the uppermost layer to the bottom layer. It is also helpful in preventing excessive leaching of nutrient ions while maintaining an appropriate pH which directly influences nutrient availability and the growth of plant, animals and microbes. The soil conservation measures on watershed basis have proved to be more effective. The Centre has also stressed the need to reduce incidence in forest fires and increase the forest base in India.
