Sustane 8-2-4 All Natural Fertilizer | 50lb - OMRI Listed

Slow-Release Organic Nitrogen Fertilizer for Turf and Landscape, 50lb

Fast-release nitrogen fertilizers can push a burst of top growth followed by a fade as the nitrogen depletes, which is a poor fit for lawns and landscape beds that need steady feeding over weeks rather than a single spike. Sustane's 8-2-4 formula releases its nitrogen slowly in organic form over 6 to 12 weeks, replenishing the soil with humus and nutrients derived from biologically stable compost, natural sulfate of potash, and feather meal.

This 50lb All Natural size suits a landscape crew or turf operation feeding larger areas who wants a bulk bag rather than restocking smaller retail bags repeatedly through the season.

About Sustane Natural Fertilizer

Suståne Natural Fertilizer, founded in 1988 in Cannon Falls, Minnesota, builds its 8-2-4 formula around the same compost-derived, slow-release nitrogen approach used across its product line, manufactured domestically and exported to more than 60 countries for agriculture, turf, and landscape markets.

Frequently Asked Questions

How often do I need to reapply this 8-2-4 fertilizer?

Because nitrogen releases gradually over 6 to 12 weeks rather than all at once, a single application feeds the lawn or landscape bed for weeks instead of needing weekly reapplication. Actual release speed varies with soil temperature and moisture.

What does 8-2-4 mean?

8-2-4 refers to the guaranteed percentages of nitrogen, phosphorus, and potassium, in that order, with nitrogen the dominant nutrient. That nitrogen-forward ratio suits lawns and landscape plantings that need steady green growth more than heavy phosphorus or potassium input.

What ingredients supply the nutrients in this formula?

The formula combines biologically stable compost, natural sulfate of potash, and feather meal. Together these ingredients supply the guaranteed nutrient analysis along with humic acids and organic matter that build soil structure.

Is this fertilizer OMRI Listed?

Yes, Sustane's 8-2-4 formula is OMRI Listed, certified for use in organic production and lawn care. That certification carries across every package size in this formula, from the smaller retail bags to the bulk 50lb bag.

Why do the 50lb bag and the smaller bags carry different product names?

The 50lb 'All Natural Fertilizer' and the 5lb/20lb 'Lawn & Landscape Plant Food' share the same 8-2-4 slow-release formula. Sustane markets the larger bag to professional landscape crews and the smaller bags to homeowners maintaining lawns and landscape beds.
