What Are Soil Crumbs?
Soil crumbs are the various types of mineral particles along with organic matter that make up soil.
Soil crumbs are a few millimeters in diameter.
The network of pores between the crumbs hold air and water, and this is where roots grow and soil creatures live.
Worms and other organisms of the soil help to form these soil crumbs, which serve as the food or organic bulk of the soil and enriches it, since they break down compost in soil.
Where soil structure is good, these crumbs do not break down easily, and can survive battering by rain and cultivation.
