SOIL QUALITY ASSESSMENT & TESTING
The quality of the soil is defined by both its physical and chemical properties, and the study and analysis of these properties is called soil testing.
When it comes to soil testing a lot of different parameters are tested. The different parameters and the tests employed to analyze them are as follows:
The gravity of the soil is the ratio of the unit weight of soil solids to that of the water. The Density Bottle Method and Pycnometer Method are the common methods of testing gravity.
The water in the soil or its moisture content is calculated through the difference in the weight of the normal soil and its weight on drying.
This parameter tells about the critical water contents in the fine-grained soil. Based on this water content the soil may be classified as solid, semi-solid, plastic, or liquid.
The dry density of the soil is the ratio of the mass of solids to the total volume of the soil. The Core cutter test is commonly employed to calculate this parameter.
Includes Organic, inorganic, Hydrocarbons and heavy metals.
