Gypsum Compost Additive

Enrich Your Compost

Composting is the biological decomposition of organic material into a humus-like substance called compost. The process occurs naturally, but can be accelerated and improved by controlling ingredients and environmental factors. Whether you are a hobby composter, or a much larger commercial entity using windows or aerated bunkers, gypsum compost additive is a valuable tool in producing quality compost.

Why Use Gypsum Compost Additive?

Gypsum compost additive minimizes the greasiness compost tends to have. It increases the flocculation of certain chemicals in the compost, enabling them to adhere to organic matter. A side benefit of this phenomenon is that air can permeate the pile more readily, and air is essential to the composting process.

USA Gypsum also aids in the composting process by reducing nitrogen losses. It ties up this nitrogen as ammonium sulfate, improves compost aeration, and enhances the microbial growth. Retaining nitrogen increases heat and reduces unpleasant odors.

Using gypsum compost additive produces more valuable compost by providing calcium, sulfur, nitrogen and trace minerals to the basic compost.

How to Use Gypsum Compost Additive

Blend 1 lb. with each wheel barrow load, or 40 lbs. per ton of dry matter, when beginning the compost process.

Combining organic nitrogen rich material streams with gypsum can reduce the release of ammonia and conserve nitrogen in the compost. This effect can be enhanced if the carbon / nitrogen ratio of the materials is 30:45. The gypsum in the final compost also benefits certain soil types such as those lacking calcium and sulfur or those high in sodium.
