About Us

At California Organic Fertilizers, Inc.™ (COFI™), we believe that farming is a biological process, not a chemical one.

Our History

Since 1990 , COFI™ has produced premium, organic, Nitrogen-based fertilizers. Use of our products has resulted in increased yields and the highest quality produce available.

COFI™, founded in 1990, is a pioneer in the development of organic fertilizers for organic agriculture. COFI™ products are designed to function in diverse geographic and environmental conditions. COFI™ agronomists are available at no cost to assist in the development of a complete fertility program resulting in high quality yields while building soil fertility through proper management of the Soil Food Web.

We are dedicated to the development and growth of sustainable and organic farming techniques and products, so we use pure, natural, organic raw materials to produce high Nitrogen, Phosphorous and Potassium products.
