Global climate changes refer to the physical or anthropogenic changes of organic and nonorganic processes that define planet Earth. These take the form of different components that can interact with each other and between which we find: the change in atmospheric composition, climate change, land use change, biodiversity and soil erosion etc. By definition, agriculture brings together all the elements of the processing environment, including soil as support for the production of vegetable and animal products for human use. These activities related to agriculture have a history of over 12 thousand years, so that subsequently followed a lot of innovations, both technical and organizational, which made agriculture today a sector highly productive, especially in countries industrialized. In recent decades, the agricultural sector has been under intense pressure coming from increasingly obvious requirements of environmental protection. The contribution of agriculture in terms of pollution and environmental degradation, as well as contributing to local and global climate change, including over-exploitation of natural resources are already familiar, which imposed standpoints. Given this situation, the stakes research on soil cover is becoming increasingly important. This paper aims to make a contribution to the knowledge about the causes that led to some problems of agricultural environment and help explain the difficulties encountered today to solve them.
