Our Farm Compost is made up primarily of leaves. There are also woodchips, manure, food waste, grass, and paper lawn bags.

We do not add any chemicals in the production of our Farm Compost. Our product is tested annually and no detectable levels of chemical residues have been found to date. When organics are collected and dropped off at our site we do not accept trash or plastic.  However, we occasionally find bits of plastic in our materials that our screener was unable to sift out.

Our Farm Compost is a nutrient rich soil like material that is the result of decomposed organic matter that is ideal for top dressing or mixing with your
existing soil.

Supersoil is our 50%-50% blend of our Farm Compost and sandy topsoil that is ideal for direct planting or other yard applications.

We recommend that you blend Farm Compost into existing soils at a ratio of up to 50% compost to 50% existing soils. Or, you can use Farm Compost as a top dressing by applying 1-2 inches on top of your existing soil. This helps soil retain moisture and decreases the need for frequent watering while additionally preventing weed growth. We like spreading corn gluten or Preen (available at most garden centers) over the bed to prevent weeds from sprouting throughout much of the growing season. For new beds or filling in spots we recommend our pre-blended Supersoil which has a 50%-50% blend of our Farm Compost and sandy topsoil.

Our products have an average pH of 7.8.
