All purpose broadcast and side dress balanced fertilizer for leafy crops, vegetables, flowers, and cucurbits. 

Description

Suståne 5-2-4 All Natural Slow Release Nitrogen Fertilizer provides 6 - 12 weeks of nitrogen in the organic slow-release form and complies with the National Organic Program standards. Suståne replenishes the soil with a rich supply of humus (stabilized organic matter) and all of the essential naturally chelated nutrients required for sound and long term soil building programs. Suståne 5-2-4 All Natural is derived from biologically stable organic compost plus natural sulfate of potash and feather meal.

Stabilized Organic Matter

Suståne 5-2-4 All Natural Slow Release Fertilizer was designed with the knowledge that the best way to grow quality plants is to develop and maintain a healthy soil. While synthetic fertilizers supply plant growth nutrients, they do not supply the organic matter required to maintain quality plant life.
