Soil Fit is designed to complement your regular fertilizer applications by improving the soil environment where roots grow. With a mild nitrogen and potassium boost, it provides gentle green-up while focusing on long-term soil conditioning and nutrient availability.

Humic acid enhances soil structure, increases water and nutrient retention capacity, and fosters a more favorable environment for beneficial microbes. Sea kelp helps turf resist heat, cold, and drought stress, while protein hydrolysates provide amino acids that support recovery and plant performance. Calcium helps strengthen cell walls and promotes overall plant structure. Natural organic meals provide slow-release nitrogen to sustain soil biology without excessive growth.
