Turf Soil and Diagnostics (TSD) is a physical evaluation laboratory and agronomic consulting company. To service our customers, we have laboratories located in Kansas and New York. Both laboratories are accredited by the American Association for Laboratory Accreditation, and we are on the USGA list of recommended labs. Our labs have been in business since 1991, and we have performed testing and/or consulting for over 1,000 golf courses located throughout the world.

TSD provides industry leading testing services to the architect and to the project. We specialize in the physical evaluation of soils, sands, and amendments. Although our services can assist in many ways, we are primarily used in the following areas.

1) Evaluation of existing golf courses and problem diagnostics. Laboratory testing packages range from topdress sand evaluations to bunker sand quality determinations to complete diagnostics of the golf green rootzone. TSD reports provide guidance for material selection, maintenance practices, and aid in determination of renovation needs.

2) Evaluation of materials that are to be used for new construction or renovation. TSD’s assessments help determine if proposed materials meet project specifications, USGA recommendations, or other project goals. Quality control testing programs verify quality, consistent materials are used for construction of tees, fairways, bunkers, and greens.

3) Innovative research and development for turf organizations and suppliers serving the golf course industry. TSD provides scientific data regarding the benefits and potential uses of products and practices.
