Abstract :

Soil is one of the most important parts of the renewable natural resources, which is damaged by cutting down the trees. If this valuable resource is not protected, the output of it is reduced and the life of mankind and plants are endangered. Soil conservation is a crucial issue and understanding how it is influenced by different factors is of utmost importance in agroforestry systems. The efficiency of agroforestry systems for regulating soil erosion can be increased in response to the similarities between these systems to the natural forest concerning the litter frequency, distance and height of trees. This study was conducted to determine the best agroforestry systems in respect to erodibility along with soil conservation. The results of this investigation comprise diverse aspects. The two important aspects of this study include (1) identification and recording the number of systems, operations and agroforestry technologies present in the area and (2) exploring the soil condition of agroforestry systems, available in the area as well as conserving the soil in these systems. Regarding the literature reviews, 3 factors were evaluated to determine the erodibility or non-erodibility of agroforestry systems (texture, porosity and soil gravimetric moisture percent). As expected, the results of this investigation revealed that trees were appropriate candidates for soil conservation and reclamation in terms of erodibility in relation to other systems in this region.
