The soil work means those works that apply agricultural land, with different tools or machines in order to achieve into the soil and the soil surface a living environment more favorable for plant growth and culture of microorganisms useful. Soil works carried out in harmony with the other factors of vegetation aim at maintaining and enhancing soil fertility and direct agricultural production process so order to obtain favorable economic results and quality products. Soil tillage are human interventions which seek to create optimal conditions for crop development because they have less capacity to secure low soluble nutrients in forms and their productivity is exposed to environmental fluctuations (climate, soil, etc.). The chemical composition of the plant mainly reflects biological characters that are formed over time with respect to the environment. Higher plants contain 70-72% fresh water, 25 27% 3% organic matter and minerals. Nutrition is the supply of the plant nutrients, their absorption and transport to places of synthesis. The nutrient means that chemical that is absorbed into the plant and used directly or indirectly, to a lesser degree or higher, photosynthesis and other physiological processes. The processes by which nutrients are contained in various organic and inorganic structures, or used for energy, is called metabolic processes.
