Soil pollution can be controlled by the following measures:– By reducing the use of plastics. By controlling the use of chemical fertilisers , pesticides, weedicides & insecticides etc. Soil erosion can be controlled by taking the following steps :- Planting more and more trees will result in the reduction of soil erosion. By stopping deforestation …

Clayey Soil Sandy Soil 1. Particles are fine and tiny Particles are bigger among all 2 Particles are tightly packed Particles are loosely packed 3. Holds a better amount of water Water holding capacity is minium 4. It is heavy weight It is light weight 5. Rich in humus and organic nutrients Not rich in …

Clayey soil is useful for crops for the following reasons :- It has the best water holding capacity. This soil is rich in organic matter ( humus ) Clayey and loamy soils are suitable for growing cereals like wheat, rice etc. Water holding-capacity of clayey soil supports the growth of crops like paddy which require …
.Soil is formed due to the weathering of rocks. Weathering of rock by physical ( air, water, temperature rainfall etc ), chemical and biological decomposition process . In the weathering process, rocks are converted to small pieces, which eventually turn to soil particles to form a layer of soil.
Soil holds water in it, which is called soil moisture. The capacity of a soil to hold water is important for various crops.
The removal of land surface by water, wind or ice is known as erosion. Plant roots firmly bind the soil. In the absence of plants, soil becomes loose. So it can be moved by wind and flowing water. Erosion of soil is more severe in areas of little or no surface vegetation, such as desert …
Calculate the rate of percolation by using the following formula: percolation rate (mL/min) = amount of water (mL) / percolation time (min) For example, suppose that for a certain sample, it took 20 minutes for 200 mL to percolate. So,rate of percolation = 200 mL/ 20 min= 10 mL/min Calculate the rate of percolation in …
The soil is classified on the basis of the proportion of particles of various sizes. If soil contains greater proportion of big particles it is called sandy soil. If the proportion of fine particles is relatively higher, then it is called clayey soil. If the amount of large and fine particles is about the same, …

The mixture of rock particles and humus is called the soil.
Each layer differs in feel (texture) colour, depth and chemical composition. These layers are referred to as horizons. The uppermost horizon is generally dark in colour as it is rich in humus and minerals. The humus makes the soil fertile and provides nutrients to growing plants. This layer is generally soft, porous and can retain …
