Abstract
The soil is a cover of unconsolidated substance initiate at the earth’s surface that has been influenced by the soil forming factors: climate, relief, parent material, time, and organisms. Soil is the basic substrate on which all life depends. The soil physical properties (texture, structure and organic matter) control the total pore space and pore size sharing in soil. Water movement in soil occurs under saturated and unsaturated conditions though soil pores. We need to determine the physical properties of the soil because they are key to allowing roots to grow and to that all—important balance between air and water in the soil. Soil itself is very complex. It would be very mistaken to consider that the soils as just a compilation of fine mineral. Soil also contains air, water, dead organic substance, and a variety of categories of living organisms.
