​SOILMATE® CompostCompost benefits the soil where it is used by improving drainage and moisture absorption, especially in soils that are otherwise poor quality. This makes growing in various types of soils easier and more productive. Compost also benefits the plant matter grown in the soil by providing nutrients to the plant’s growing area. Compost helps reduce runoff, making the use of fertilizer more productive and keeping it out of the water. 

Environmentally, the use of compost has been shown to remediate, or clean up, contaminated soils by reducing toxic runoffs, binding certain toxins that might otherwise escape, and it prevents erosion when used near roadways, lakes, rivers, and streams.

Mulch & Compost

KARBON® Leaf MulchThe purpose of using any mulch is to beautify, retain moisture and help to cool the soil during the hot summer months. Karbon® Leaf Mulch consists of nothing but leaves which are ground up and then through a natural process, heated to 140 degrees or more to kill any dormant weed seeds. Water is added to activate the tannins and accelerate the darkening process. The leaves are then screened to achieve a consistent ½” minus product.
