Soil types
- Clay soils are heavy, high in nutrients, wet and cold in winter and baked dry in summer.
- Sandy soils are light, dry, warm, low in nutrients and often acidic.
- Silt soils are fertile, light but moisture-retentive, and easily compacted.
- Loams are mixtures of clay, sand and silt that avoid the extremes of each type.

Which soil is rich in nitrogen?
In sand soils, the best balance is achieved by a “Moderate” soil nitrogen supply (25 – 50 mg-N/kg soil). In contrast, in loam and clay soils “High” soil nitrogen supply is most suitable (50 – 75 and 75 – 125 mg-N/kg soil respectively).
How do I know my soil type?
To determine the percentage of each soil type, you need to do a little math. If, for example, the total amount of soil is 1 inch deep and you had a 1/2-inch-thick layer of sand, your soil is 50 percent sand. If the next layer (silt) is 1/4 inch deep, you have 25 percent silt. The remaining 25 percent, then, is clay.
What are the different soil types explain?
Soil can be classified into three primary types based on its texture – sand, silt and clay. However, the percentage of these can vary, resulting in more compound types of soil such as loamy sand, sandy clay, silty clay, etc.
What is nature of soil?
The soil is a natural body embracing not only the topsoil, but also the subsoil and other layers above its parent rock. The dynamic or active soil, as defined in this way, correlates well with the kinds and distribution of soil organisms, with plant growth, with land capability, and with land use.
Which type of soil is best for construction?
Loam: An ideal soil type for home construction, loam consists of silt, sand and clay. Dark and dry, loam is crumbly and soft to the touch. Because it is evenly balanced, loam is able to hold water at a more balanced rate.
