The labs that make up Turf & Soil Diagnostics (formerly Hummel & Co and Turf Diagnostics & Design) have combined 50 plus years of providing quality testing services and data driven advice. We have performed testing for thousands of golf courses, sports fields, landscapes, and agricultural sites located throughout the world.
Our services include laboratory testing of soil, growing media, sand, aggregates, and amendments. Subgrade and rootzone evaluations are our specialties. We also perform research and development, on-site evalutions, and Gmax field hardness testing.
Note: Turf & Soil Diagnostics does not accept samples containing hazardous materials. Our labs only work with clean soils, sands, amendments, etc.
