Alliance

Utah Seabed partners with TC Alliance Foundation.

Mineral-rich soil, food education, and Indigenous land stewardship in one protocol. Utah Seabed is a mineral partner. We do not speak for tribal nations.

Terra Community Alliance Foundation is a Utah 501(c)(3) private foundation. Its mission is restoring soil health and reclaiming food sovereignty with Indigenous nations, using nutrient-rich natural amendments and regenerative practice. Partnership with the foundation is not a claim of tribal endorsement of Utah Seabed.

Soil and food sovereignty

The foundation partners with Indigenous nations to restore soil vitality using mineral-rich amendments, blending Traditional Ecological Knowledge with soil science.

Garden sample kits

Instruction by Abigail Cyr walks growers through a simple amendment sequence: reduce water, increase yield, and drive nutrients into soil.
