Professional Grade 

Suståne products are derived from biologically stable humus-rich compost and contain both water soluble nitrogen (WSN) and slow release nitrogen (SRN), beneficial microbiology, and all 17 elements essential for plant photosynthesis. With a near-neutral pH, a low salt index and low ammonium nitrogen percentage, Suståne will not cause seedling stress or plant fertilizer “burn”. Suståne products increase soil cation exchange capacity (CEC) by supplying humates and stable organic matter. Suståne’s organic and blended natural fertilizers provide all soil types with additional buffering capacity, allowing for more consistent and productive growth.
