Thank you for visiting us at the GIS 2026 Trade Show!

We appreciate you taking the time to connect with us at GIS. Since 1988, EarthWorks has partnered with golf course superintendents to improve turf performance by focusing on carbon-based fertility and the principles of Biological Soil Management.

Our approach is simple: build healthier soils to support stronger roots, improved nutrient efficiency, and more consistent playing conditions throughout the season.

Learn More About Our Approach

EarthWorks manufactures a full line of Replenish® granular carbon-based fertilizers and Foliars+® liquid fertilizers designed to support soil biology, reduce stress, and improve turf resilience from tees to greens.

But more importantly, we help superintendents understand why their programs work and how to apply them with confidence.

EarthWorks Replenish Granular Fertilizers

Replenish Dry Fertilizers

The Replenish granular fertilizers make everything in your fertility program work better. A volume of carbon feeds the microbes and the plant, and balances the C:N ratio.

Foliars+ Liquid Fertilizers

The Foliars+ liquid fertilizers powered by BioCharge round out the volume of carbon added to the soil. The nutrients get into the plant quickly, feed microbes, and speed up nutrient uptake.
