Answer:

Explanation:

Crumbs are referred to as the large pieces of aggregated soil present as lumps. They need to be crushed and grounded and this is done while ploughing and tilling of land before land is prepared for sowing. This is done with the help of iron leveller or wooden plank in smaller areas or power tillers in large areas. This is done so that there is proper space for roots to penetrate, for better air circulation and good germination of seedlings.
