FAQs

What Is 8-0-3 Soil Fit Used For?
8-0-3 Soil Fit is a natural-based granular bio-stimulant and soil amendment designed to improve soil health, structure, and nutrient efficiency. It provides a mild nitrogen and potassium boost for gentle green-up while supporting long-term turf recovery and root-zone health.

How Does 8-0-3 Soil Fit Improve Soil Health and Turf Growth?
Soil Fit combines natural carbon sources from feather meal, soybean meal, and wheat flour with humic acid, sea kelp, protein hydrolysates, and calcium. These ingredients help support soil structure, water and nutrient retention, beneficial microbial activity, root development, and turf recovery from heat, drought, cold, or other environmental stress.

How Much 8-0-3 Soil Fit Should You Apply per 1,000 Square Feet?
Apply Soil Fit at 3 pounds per 1,000 square feet. An 18-pound bag covers up to 6,000 square feet, while a 45-pound bag covers up to 15,000 square feet. Apply to dry turf and water in within 48 hours with at least ¼ inch of rainfall or irrigation. Apply three to four times per year during spring, summer, and fall while the grass is actively growing.

Can 8-0-3 Soil Fit Be Used on All Grass Types?
Yes. Soil Fit can be used on established cool-season grasses, including Kentucky bluegrass, turf-type tall fescue, and perennial ryegrass, as well as warm-season grasses such as bermuda, St. Augustine, zoysia, centipede, and bahia. Always follow the product label for application timing and instructions.

Is 8-0-3 Soil Fit Safe for Pets and Children?
