Sustainble use of forest soils should ensure that the following requirements are met under the different soil environment ecoscapes in the country.
Maintenance of the natural soil depth
Maintenance of soil pH and physical structure
Maintenance of a desirable level of soil flora and fauna
Forest soils in Sri Lanka can be considered under two broad categories.
1.Forest soils under natural forest
2. Forest soils under man - made forest
Major differences in soil fauna and flora could exist between these two broad categories. These should be properly described and characterized in order to be able to monitor long term trends.
Soil depth, soil pH and physical structures of the different kinds of forest soils in the country can be readily inferred from the available information of the great soil groups identified, characterized and mapped over the last four decades. It is therefore possible to monitor long term trends in respect of these soil properties.
The degree of robustness, fragility and reliance of the more important great soil groups of this country are now properly understood. Sustainable management and use of forest soils should, therefore, be viewed from the background of the occurrence and distribution of the forest soils across the different great soil groups of the country, by also taking into account the nature of soil resilience of the different soils.
