21-4-10 Organic-Based

SKU: TL07128463

Explore the benefits of our RichGROW 21-4-10 "Organic-Based" blended fertilizer – a premium-grade solution tailored for golf courses' fairways/roughs, sports fields, and residential lawns. This standard-sized (240 SGN) fertilizer is enriched with slow-release nitrogen, making it an excellent choice for late summer through fall applications and a reliable dormant winter feed.

Carefully formulated, this fertilizer contains an impressive 54% Controlled Release Nitrogen (CRN), sourced from stabilized nitrogen and organic components. The high CRN content minimizes surge growth and extends the green-up response for an impressive 10 weeks, while effectively preventing nitrogen loss to the atmosphere through volatilization and nitrate leaching into groundwater.

Specifically designed for soils with a high Cation Exchange Capacity (CEC), such as clay soils, our 21-4-10 fertilizer excels in enhancing soil structure. Packed with organic-based ingredients, it not only boosts the CEC but also serves as a valuable carbon source for beneficial bacteria and fungi, fostering a healthier soil environment.

As an added bonus, this fertilizer includes sulfur and iron, providing an extra nutritional kick for optimal plant health. Elevate your turf management with our time-tested 21-4-10 "Organic-Based" blended fertilizer – the trusted choice for sustained, vibrant greenery and soil health.
