Answer:
Preparation of soil is the first step before growing of crop. It helps to turn the soil and loosen it to allow the roots to penetrate deep into it. The loosening of the soil helps in the growth of several soil microbes, earthworms etc., which enrich the soil with humus and other essential nutrients.

Answer:
Adding organic matter to soil before planting also improves water absorption by growing plants. When soil is heavy clay, adding a mixture of leaves, lime, compost, manure, coarse sand and peat moss helps to break up and lighten the soil, whereas sandy soil benefits from the addition of aged manure, sawdust or clay.
