Why does digging over a compost heap help decomposition?

Answer 1

That it encourages organic breakdowns by Mother Nature's scavengers is the reason why digging over a compost heap helps decomposition.

Specifically, soil does not just function to help a plant's below-ground parts grow. It also helps support macro- and micro-scopic organisms that are part of what is called the soil food web. Digging over a compost heap will encourage the organisms that specialize in decomposing carbon- and nitrogen-rich matter to facilitate the breakdown of compostable materials.

Answer 2

That it encourages organic breakdowns by Mother Nature's scavengers describes the reason why digging over a compost heap helps decomposition. Soil hastens the growth of below-ground plant parts and the sustainability of macroscopic and microscopic organisms that number among the soil food web's membership. Digging over a compost heap will encourage the organisms that specialize in decomposing carbon- and nitrogen-rich matter to facilitate the breakdown of compostable materials.
