Yogita Ingle 7 years, 2 months ago

The first step before growing a crop plant is the preparation of soil for sowing of seeds, the soil has to be loosened so that the roots of plants may penetrate deep into the soil, the loosening of soil allow the roots to breathe easily because loosened soil promotes growth of organisms like earthworms and microbes which are the farmer friends as they further turns and loosen the soil and add humus to it, apart from this turning and loosening of soil brings the nutrient rich soil to the top and the top layer of soil supports plant growth, thus nutrient rich soil at the top layer helps in good and healthy crop and hence turning and loosening of soil is very important for cultivation of crops. The process of loosening and turning of the soil is called tilling or ploughing and is carried on by using a plough.
