The California Department of Food and Agriculture has certified two soil amendment products from The Andersons as meeting the standards for Organic Input Material in California.

Humic DG and Black Gypsum DG feature The Andersons patented Dispersing Granule Technology that provides dry, spherical, and easy-to-apply granules that dissolve quickly into thousands of micro particles upon contact with water. Humic DG and Black Gypsum DG can be applied through variable rate technology equipment, or directly applied in in-furrow, bedding, broadcast or strip tillage methods. Humic DG and Black Gypsum DG also can be blended into all fertilizers materials, including urea.
Both can be used in a wide range of applications including fine turf and ornamental uses.
The Organic Input Material Program registers fertilizing materials to be used in organic crop and food production. The program is mandated by the California legislature, and products purported to be appropriate for use in organic production are verified to comply with the California Fertilizing Materials Law and Regulations and USDA National Organic Program Standards.
