Explain why ploughing is important for crops.

Explanation

Ploughing loosens the soil and provides necessary aeration to it. The loose soil allows the root to breathe easily even when they go deep into the soil. Hence, loosening or turning help roots to breathe easily. Such soil also helps in the uniform mixing of the fertilizer. The aerated soil helps organisms such as earthworms and microbes to grow in it. These organisms help decompose dead plants and animals and further enrich the soil with nutrients or add humus to the soil.
