Answer

Brief Explanations:

Humus increases soil porosity by creating pore - spaces as it decomposes and by binding soil particles loosely. It does not decrease soil porosity. Humus expands with moisture, improves water and air movement in soil, and is a basis for soil life.

Answer:

C. Humus decreases the porosity of soil.
