The effects of compost on soil health are almost exclusively related to the direct addition of soil organic matter to the soil with several benefits for soil's chemical, physical, and biological properties.
Compost is a great source of plant nutrients that, if used as fertilizers, can contribute to closing the loop of nutrients in agriculture. The C-rich organic compounds in compost are a source of energy for soil microorganisms.
The use of compost is known to improve soil structure, water-holding capacity, and infiltration rates. These changes in soil physical properties, and water cycling and retention capacity, are directly associated with the increases in soil organic matter and biological activity with compost application.
Compost Connector, Zero FoodPrint's newest program aims to make the best use of California’s rapidly increasing supply of compost by directing it to farms and ranches.
