What is compost?

At the simplest level, compost is wetted organic matter known as green waste (leaves, food waste) that has broken down into break down into humus after a period of weeks or months.

Compost is rich in nutrients, and used as a soil conditioner, a fertilizer, and as a natural pesticide for soil. In ecosystems, compost is useful for erosion control, land and stream reclamation, wetland construction, and as landfill cover.



This product is really a “finished” mushroom compost with a basically neutral pH (6.5 to 7.5). “Finished” means it is fully decomposed (broken down to a fine, black, soil-like structure). Lab tests rate this product from very good to excellent in NKP (ppm rates) and other essential trace elements required for healthy plant development. It has outstanding water absorption quality, permitting absorption of 80% of its weight (by contrast clay allows only about 15%). Humus is a premium soil amendment used in preparing holes for planting vegetable gardens, ornamental shrubbery and flowerbeds or as a topdressing when seeding or sodding your lawn.


Modern, methodical composting is a multi-step, closely monitored process with measured inputs of water, air, and carbon- and nitrogen-rich materials. The decomposition process is aided by shredding the plant matter, adding water and ensuring proper aeration by regularly turning the mixture. Worms and fungi further break up the material.
