The Organic Fertilizer Association of California (OFAC)
The Organic Fertilizer Association of California (OFAC) represents the interests of organic fertilizer producers, distributors and retailers that provide organic fertilizer to the agriculture and horticulture industries. OFAC is dedicated to increasing public knowledge of biological and organic cultural systems. The association was formed in 2007 and is guided by an elected board of directors representing the California organic fertilizer industry.
OFAC members provide fertilizer products that meet the USDA National Organic Program’s (NOP) standards and many members also provide guidance to growers on how to improve soil health and fertility through organic farming methods.
