What is BioPreferred certified?

BioPreferred certified products are certified by the USDA BioPreferred® Program, which means that these products are:

More earth-friendly than non-biobased alternatives— use of organic material, use of locally sourced ingredients, use of sustainable
manufacturing practices, etc.

Safer and less toxic than non-biobased alternatives— organic product safer to use.

What Are Biobased Products?

According to the USDA Biopreferred Program:
The term "biobased product" means a product determined by the U.S. Department of Agriculture (USDA) Secretary to be a commercial or industrial product (other than food or feed) that is- (A) composed, in whole or in significant part, of biological products, including renewable domestic agricultural materials, renewable chemicals, and forestry materials; or (B) an intermediate ingredient or feedstock. Biobased Products are derived from raw materials such as plants and other renewable agricultural, marine, and forestry materials. Biobased products generally provide an alternative to conventional petroleum derived products and include a diverse range of offerings such as lubricants, detergents, inks, fertilizers, and bioplastics. For the purposes of the BioPreferred Program, biobased products do not include food, animal feed, or fuel. This document provides more information about biobased content and how it is determined. Products participating in the voluntary labelling initiative have their biobased content measured using ASTM D6866 as part of the certification process.

What is OMRI-listed?

NutriHarvest® organic fertilizers bear the OMRI Listed®
Seal to indicate their strict compliance for use in organic production, handling, and processing. An individual gardener or a commercial grower
can now nurture their plants confidently using a product that meets the most stringent organic standards.
