Organic fertilizers are derived from plant, animal, or mineral resources, and combined with organic matter. They are ideal for enhancing soil fertility and stimulating plant growth in a sustainable and environmentally friendly way. Organic fertilizers add nutrients to the soil for uptake by plants and for use by the myriad of microorganisms that inhabit healthy, productive soil. Many DTE™ fertilizers are approved for use in organic crop production. Please note the “OMRI” and “OIM” logos throughout the website. Certified organic operators are encouraged to check with their organic certifying agent to determine if any given product is acceptable before purchase, application and inclusion in their organic farm plan.

Organic Materials Review Institute (OMRI) independently reviews products and lists those that are suitable for use in organic crop production under the USDA National Organic Program Rule.

The Organic Input Materials Program registers fertilizing materials to be used in organic crop and food production. Approved products comply with the requirements of the California Fertilizing Materials Law as well as the USDA Organic Program standards.
