Explanation:
It is the first method to be followed before growing a crop. This method is usually employed for loosening the soil to allow the root to
penetrate deep into it. The loosening of the soil helps in the growth of several soil microbes, earthworms etc., which enrich the soil

is called tilling or ploughing the soil. Tilling of soil brings the nutrient-rich soil to the top. This helps the plants to utilize the nutrients
for their growth.
