What Knox Fertilizer does
Knox Fertilizer Company, Inc. is a third-generation, family-owned manufacturer of fertilizers, herbicides, insecticides, and ice melt products headquartered in Knox, Indiana. Founded in 1950 by Robert and Georgia Shaw and still controlled by their descendants, the company operates a dual-market model spanning a professional turf segment — serving golf course superintendents, sports turf managers, and professional lawn care operators through direct B2B sales under the Shaw's, SurfCote, XRT, and One & Done brands — and a consumer segment distributing Schultz, Twin Pine, and Gro-Fine lawn-and-garden products through retail channels to homeowners. The company also sells ice control products (Knox Ice Melter and Premium Remove Ice Control) for both commercial and residential de-icing use.
The company's core technical platform is its proprietary polymer resin encapsulation technology, branded SurfCote and XRT, in which each fertilizer granule is encased in a durable micro-thin shell. Soil moisture diffuses into the granule and dissolves the urea core; rising temperatures then liquefy the urea, which slowly passes through the polymer membrane to deliver nutrients over a period of up to 90 days. This controlled-release mechanism is integrated into combination products such as One & Done, which pairs SurfCote nitrogen with Acelepryn and Dimension herbicides and insecticides to deliver season-long weed and pest control in a single application.
Knox's revenue model is overwhelmingly product-based: professional customers receive quote-based pricing through a dedicated Quote Engine, while consumer brands flow through retail distribution. The company supplements its in-house R&D with an extensive partner ecosystem spanning nine agrochemical and specialty input suppliers — BASF, Bayer Environmental Science, Corteva Agriscience, FMC Corporation, Gowan Company, Syngenta Professional Products, Nufarm Americas, PBI Gordon Corporation, and KMB Technologies — that contribute active ingredients, complementary technologies, and distribution reach. Geographically, the Northwest Indiana headquarters positions Knox within reach of most major U.S. metropolitan markets between the Appalachians and Rockies, with reported market concentration in the Midwest region.

- The Andersons (Professional Products): The Andersons' lawn and professional turf division (under Andersons Lawn) and its Plant Food Group (NutriDG, XF, etc.) sell controlled-release fertilizers, herbicides, and combination products to golf courses, sports turf, and lawn care operators - a direct overlap with Knox's SurfCote, XRT, and One & Done portfolio on technology and customer profile.

Broad incumbents
- ICL Specialty Fertilizers (Everris): ICL Specialty Fertilizers (formerly Everris) is a global leader in controlled-release fertilizers (Osmocote, Sierrablen, Sportsmaster) serving turf, horticulture, and ornamentals. It is a much larger competitor of Knox in the controlled-release professional turf segment with international scale Knox lacks.

- Lebanon Seaboard (parent of LebanonTurf): Lebanon Seaboard Corporation is the diversified parent of LebanonTurf and Pro Division, producing both consumer and professional turf fertilizer lines plus animal/paddock products. The Pro Division is a direct peer of Knox in professional turf, while the broader portfolio competes for shelf in consumer channels.
Emerging players
- Nufarm Americas: Nufarm is a global crop protection and seed treatment company with a US turf-and-ornamentals business that competes in the same golf and lawn care segments as Knox, particularly on herbicides and combination products.

- CPRL/Central Marketing / Helena Agri-Enterprises: Helena Agri-Enterprises distributes specialty fertilizers, crop protection, and turf inputs across the Midwest and Southeast, often blending and formulating with custom chemistry.
