Plant Available Nitrogen (PAN) Conversion Chart

Use this formula to calculate how much Nitrogen will be available to your plants or crop during the growing season. There are huge differences between fertilizers based upon the Carbo to Nitrogen (C:N) ratio.  The higher the ratio, the lower the available Nitrogen. Variances range from 50% to almost 100% for organic fertilizers.

Soil Food Web Program™

California Organic Fertilizers, Inc.™ (COFI™) has developed a Soil Food Web
Program™ for growers using COFI™ fertilizer products. Please feel free to contact us for further information on this exciting and innovative program.

All farming practices affect the Soil Food Web. Our Soil Food Web Program™ takes into consideration a long list of production variables including plant variety, irrigation methods, tillage, season, geography and fertilization. The COFI™ Soil Food Web Program™ evaluates these variables when assessing the crop, both above and below ground. Soil samples are sent to both a chemical lab and biological lab for assessment. Later, during the growing cycle, plant samples are again tested and infrared thermal photography is employed to gain further feedback.

Since fertilization has a major impact on the Soil Food Web, COFI™ is developing a Food Web Rating™ (FWR™) for all of our products using an upper and lower baseline to determine effectiveness of the product. The FWR™ takes into consideration biological and chemical aspects of the product. COFI™ is conducting biological growth tests as well as chemical analysis of each product in order to determine the impact on the soil micro-organisms and the Soil Food Web as a whole.

Based upon the FWR™ and the production variables, a unique and complete Soil Food Web Program™ is designed. Since not all crops are grown under optimum growing conditions, a combination of nutrient inputs, along with various Food Web Ratings™, will be necessary to produce the desired quality crop AND provide the best Soil Food Web management for the farm.
