definition of the preparation of soil
Answers
Preparation of ssoil:-
Soil is prepared by weathering of rocks. The rupture of rocks by the action of air, wind and water cause soil formation.
• When the rock has broken into small particles, it's small particles combine with humus (organic matter) to form soil.
When plants, their leaves, remains of animals were found rotting in soil. And similarly, bacteria and other micro-organisms along with the mineral elements present in this sand continued to make other complex and useful substances. Soil is prepared by continuously running this sequence for thousands of millions of years.
• Although, soil can prepare by rocks too. Soil is actually caused by water 'cutting' or 'grinding' the rocks, but this process of making soil from rocks is also very slow.
- In nature, this complex work of making soil from rocks and then from sand seems like work done in a laboratory.

Answer
The preparation of soll is the first step before growing a crop. One of the most Important tasks in agriculture is to tum the soil and loosen It. This allows the roots to penetrate deep into the soil. The loose soll allows the roots to breathe costly even when they go deep Into the soll. Why does the loosening of soll allow the roots to breathe easily?

Why does the loosening of soll allow the roots to breathe easily?The loosened soil helps in the growth of earthworms and microbes present in the soil. These organisms are friends of the farmer since they further turn and loosen the soil and add humus to it. But why the soil needs to be turned and loosened?

But why the soil needs to be turned and loosened?You have learnt in the previous classes that soil contains minerals. water, air and some living organisms. In addition, dead plants and animals get decomposed by soil organisms. In this way, various nutrients in the dead organisms are released back into the sol. These nutrients are again absorbed by plants.

In addition, dead plants and animals get decomposed by soil organisms. In this way, various nutrients in the dead organisms are released back into the sol. These nutrients are again absorbed by plants.Since only a few centimetres of the top layer of soll supports plant growth. turning and loosening of soll brings the nutrient-rich soll to the top so that plants can use these nutrients. Thus.turning and loosening of soil is very important for cultivation of crops.
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. This is done by using a plough Ploughs are made of wood or Iron. If the soil is very dry. It may need watering before ploughing. The ploughed field may have big clumps of soll called crumbs. It is necessary to break these crumbs. Levelling the field is beneficial for sowing as well as for Irrigation. Levelling of soil is done with the help of a leveller.
