Suståne's organic fertilizers have been formulated for the professional nursery, greenhouse, and landscape industries. We offer a range of formulations for 100% organic to organic with controlled-release fertilizer that reduces cost and enhances "green". Suståne produces predictable results, dependable performance, and high-quality plants. Blends of Suståne Organic and Controlled Release Fertilizers are the new generation of environmentally friendly fertilizers.

Great new products are born from discovery, and through years of research and development, Suståne began studying and evaluating treatment effects, plant response, nutrient release, EC rates, and other fertilizer responses to container-grown nursery plants at North Carolina State University in 1991 and 1992. Basic Suståne 4-6-4 was discovered to be the perfect base fertility complement to commercial potting soils.

In 2002 Suståne began experimenting with different formulations that combined Suståne Organic with numerous sources of slow and controlled-release fertilizers including sulfur-coated urea, methylene urea, urea form, and several types of polymer-coated NPK products.

The photo on the left shows the comparative growth differences between two identical formulations of 16-4-8 using the same controlled-release fertilizers. The only difference between treatments was that Suståne Organic was substituted for 50% of the blend in the treatment on the right. This discovery led to the development of new combinations of Suståne plus coated NPK controlled-release fertilizers available today.
