Build better soil first, then watch everything grow stronger. Including Kelp, Humic and Fulvic Acid. This organic 3-2-5 soil builder supports steady feeding, healthier biology, and improved structure—great for lawns, gardens, and raised beds.

Best For

Soil improvement, overseeding/topdressing, organic-minded homeowners, and gardens that need steady nutrition.

What Makes It Different

The key difference is that it’s designed to feed the lawn and improve the soil at the same time. Organic nutrient sources release gradually through microbial activity, which supports steadier growth and helps build a healthier root environment. Rather than acting like a quick synthetic push, it works as a long-term soil-building input—ideal for homeowners who want sustainable improvement and better lawn performance season after season.

Application Rate

Why This Fertilizer?

Organic fertilizers work by improving soil biology and providing nutrients in a slower, more natural release pattern. Instead of feeding plants immediately with synthetic nutrients, organic materials break down gradually through microbial activity. This supports beneficial soil organisms and improves long-term soil fertility. Over time, organic fertilizers help build healthier soils that retain nutrients more effectively and support stronger plant growth.
