1. Texture: The texture of the soil depends upon the relative amount of these particles. Clay has the smallest sized particles. Because of very small size, the clay is felt smooth. Silt particles are larger than the clay particles. There size range from0.002 to 0.02mm in diameter. So silt does not feel smooth. Sand particles are largest sized particles of soil. Their diameter is more than0.02mm
2. Absorption of water : Water holding capacity in different types of soils is different. Soil absorbs water because it is porous. Sandy soil holds less water than clay soil and loamy soil. Clay soil holds more water than sandy soil. Sand absorbs less water than clay. Some plants require more water to grow; they grow well in clay soil and loam soil, since sand hold less water, so less vegetation is found in sandy soil.
3. Moisture: Texture decides the water holding capacity of the soil. The soil has some amount of water inside it as a moisture. Water is usually present as a thin film around the soil particles. It is absorbed by the roots of the plants. The capacity of a soil to hold water is important for the growth of various crops. Even a dry soil has some water in it.
4. Colour:Soils are of different colours. They are red white and black. The red colour of the soil is due to the presence of iron oxide. The black colour soil is rich in minerals and humus. It is good for the growth of wheat and jowar
5. Soil pH : Soil can be acid, alkaline or neutral. Some plants grow in acidic soil (pH below 7) such as potatoes and kumara. Carrots and lettuces prefer soil with neutral pH (7.0). Soil become more acidic over time as minerals are leached away.
6. Percolation Rate: When we sprinkle water on the ground, it is soon absorbed by the soil. This is because water percolates through the soil. The process in which water passes down slowly through the sol is called percolation of water. But water does not percolate at the same rate in all types of soils.
