DTE™ Fertilizer Blends save gardeners time and labor by offering a wide variety of single ingredients in pre-mixed proportions for more general needs around the home and garden. A great advantage of organic, multipurpose blends is that they can last in the soil for several months, continuing to fertilize plants and enrich the soil long after initial application. 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 (OIM, CDFA) registers fertilizing materials to be used in organic crop and food production and comply with the requirements of the California Fertilizing Materials Law and Regulations and the USDA National Organic Program Standards.
