Meaning of rock mulching | Babel Free

Definitions

A method of improving the fertility of poor soils by adding a layer of small stones atop the soil, with perhaps some fertilizer atop the soil before adding rocks. The added rocks/stones would leech minerals from the rocky layer into the soil and have the stony layer retain moisture in the soil. The layer of stones remains in place when the area is cultivated.
