Organic Plant Establishment and Soil Builder for turfgrass and landscape applications

Suståne 4-6-4 is an all-natural organic fertilizer for landscaped areas and is ideal for turf establishment, grow in, overseeding, and sod installations. Used by professional turf managers, groundskeepers, nurserymen, master gardeners and professional growers around the world.

Suståne 4-6-4 is a compost-based organic starter and maintenance fertilizer. It replenishes the soil with a rich supply of humus and all plant essential nutrients. Suståne 4-6-4 provides a balanced mix of slow-release nitrogen and other nutrients derived from biologically stable compost, natural potash, and feather meal.

Turf Establishment
Turf establishment accelerates with Suståne 4-6-4, a complete package containing slow-release nitrogen (SRN), chelated micronutrients, organic phosphorous, and humic substances. Suståne 4-6-4 has been demonstrated time and again to surpass synthetic turf starter fertilizers and other sources of humates and plant biostimulants. Using fully composted natural fertilizers increases the levels of beneficial microbial activity, which in turn converts nutrients into plant-available forms.
