WHAT DOES COMPOST DO? Applying compost to the soil starts a
biological process that decomposes organic matter and builds
soil. In fact, the humus in compost actually feeds the micro-
organisms that are essential in keeping the process going.
Ultimately compost helps loosen clay soils by creating open
spaces that allow air and water to circulate through the soil
instead of merely running off the surface. Conversely, compost
helps unite the coarse particles in sandy soils so they can
retain water and nutrients longer. Either way, your plants get a
steadier flow of nutrients and water for optimum growth.
