Formulations for Every Application

Biologically Diverse:
Only Suståne starts with concentrated aerobic compost. Suståne has the highest known naturally available nutrient concentration available.  Suståne is then transformed into fine, homogeneous, granulated particles for uniform, consistent, turfgrass and horticultural applications. 

Biologically Stable:
Because Suståne is completely composted, it does not rob oxygen from the root zone as other “organic” fertilizers do when they decompose after application.  Suståne does not attract flies, Black Turfgrass Ataenius beetles, other insects, pests, or animals.

Nutritionally Sound:
With a base Carbon to Nitrogen ratio of 5:1, Suståne is more soluble than peat products and will not immobilize other soil-applied nitrogen.  Suståne delivers the broadest spectrum of naturally occurring Macro and Micro-nutrients complexed in a very high Cation Exchange Capacity humic base.  Biologically Active – Rich in Humic Substances.

For Every Use:
From 100% Organic Basic Suståne to Higher Nitrogen Suståne Natural Base formulations and varied release rates, there is a Suståne product for every turf type and agronomic application.
