Soil testing


Soil composition

The earth's surface by rock weathering, mineral particles gradually damaged into loose, ranging in size (called parent material). The soil is the comprehensive effect factors of soil formed and evolved in the parent material, climate, biology, topography, time etc.. Soil composition is very complex, in general, it is composed of minerals, animal and plant residue decomposition of organic matter, water and air and other solid, liquid and gas.
