Manufactured by usOur formulas, our standard

Formulation, granulation, liquids and packaging happen in the USA under one Sigma standard. When something needs to change, we change it.

Proven in the soilBiology in every granule

Humate and beneficial microbes are built into the granule, not coated on, and every program is tested in the field before it goes on a calendar.

In it for the long runPartners, not purchase orders

Many customers have worked with us for years. Our agronomists come back to check results, and we earn the next order every season.
