The role of land use and slope in soil erosion coefficient at water farming

ABSTRACT: Erosion is a complex factor of soil properties impacts and the interactions between them. Many efforts have been made in order to demonstrate the ability of soil based on soil measurable characteristics in laboratory with desert and soil reaction to rainfall a simple index of soil erosion. Water and wind erosions cause side effects such as degradation, soil fertility, environmental problems and quality and quantity reduction in agricultural products. Land use changes in the past and the present and future is one of the main causes of global changes that The changes in the physical form of earth is the most common and most important effect of it and this effect has left many complex results on ecosystem of any region. In developed countries, agriculture in the fertile lands is more lucrative than lands with less fertility. Estimation of soil erosion in each sample had been done by using Wischmeierʹs monograph and data analysis formula by using software Excel, SAS, and comparing soil erosion in different applications and different slope.
