The preparation of the soil is the first step in growing a crop. The most important tasks in agriculture are to make the soil loose. This allows the roots to penetrate deep into the soil. The loose soil allows the roots to breathe easily even when they go deep into the soil. The loosened soil helps in the growth of earthworms and microbes present in the soil, which helps in enriching the soil. Soil preparation includes ploughing, levelling, and manuring.
