The soil in each area contains different. The differences are more involved if human use of land and in every aspect. There are four components of soil, even the most
minerals - is caused by minerals and rocks. Degraded by physical chemistry and biochemistry as a source of nutrients and soil structure
, organic matter - is rotting decay. Or caused by the decomposition of plant debris. This will be a source of nutrients for the soil. It is also an energy source for soil microbes with
air - a gap between the clay or soil particles, which are pneumatic. Accounting for about 45 percent of all components
of water - is found in the spaces of the soil or soil particles
, soil quality and high yield should be proportional to the component. Minerals 45 percent, 5 percent organic matter, air and water by 25 percent to 25 percent.
