The Andersons Ecofusion Starter 16-21-4 Biosolid Fertilizer 18 lb Bag — 5% Iron, Covers 5,000 sq ft

The Andersons Professional Ecofusion™ Starter 16-21-4 is a biosolid-based starter fertilizer formulated to jump-start new turf with a balance of quick- and slow-release nitrogen, 5% iron, and essential micronutrients.

Designed for professional and serious home turf projects, this 18 lb bag supplies the nutrients needed to establish seedlings and plugs while promoting deeper green color. Its biosolid base delivers organic matter alongside measured fertilizer ratios (16-21-4 N-P-K), and added copper, manganese and zinc support turf health at the micro level. It covers up to 5,000 square feet per bag and is suitable for a wide range of turf types; note it is not sold in Connecticut or Maryland.

How does Ecofusion™ Starter help young grass establish quickly?

The formula pairs a fast-release nitrogen fraction to feed seedlings immediately with slow-release nitrogen to support steady growth over several weeks. The elevated phosphorus (21) is tailored to encourage root development, which is critical during sod-laying, seeding, or overseeding.

• 16% total nitrogen: combination of quick and slow-release sources for immediate and sustained feeding
• 21% available phosphate to support root formation and strong anchoring
• Organic biosolids provide added organic matter to improve soil structure

Will the 5% iron and added micronutrients improve turf color?

Iron at 5% contributes to deeper green without excessive top growth, and the included copper, manganese and zinc address common micronutrient shortfalls. These elements help maintain healthy chlorophyll production and can reduce subtle discoloration in young or recovering turf.

• 5% iron for enhanced greening without overstimulating shoot growth
• Copper, manganese and zinc included to correct micronutrient deficiencies
• Balanced nutrition reduces patchy coloration during establishment

How easy is this product to apply and what area does one bag cover?

The product comes in an 18 lb bag with a spreader-friendly granule size that works with common broadcast and drop spreaders. Coverage is up to 5,000 square feet per bag when applied at labeled rates; always follow the application instructions and calibrate your spreader for even distribution.

• 18 lb bag covers up to 5,000 sq ft at starter application rates
• Compatible with most broadcast and drop spreaders; calibrate for accuracy
• Granular form reduces dust and clumping for uniform spread
