What Sommerfeld does

Sommerfeld AG is a second-generation, family-owned German greenkeeping and golf course services company headquartered in Edewecht, Lower Saxony. Founded in 1983, it evolved from an agricultural contract business into a specialized provider of outsourced golf course maintenance, renovation, construction, and irrigation services, marketed under its integrated "System Sommerfeld" framework. The company maintains more than 50 golf facilities across the DACH region with a workforce of 300+ (one source cites 350+) employees deployed across customer sites, and describes itself as the German market leader ("Nummer Eins. Deutscher Marktführer in der Golfplatzpflege") in golf course care. It is the only ISO 9001-certified greenkeeping company in Germany and operates a TORO-aligned equipment fleet, an in-house R&D workshop and soil laboratory, and the AZAV-certified Sommerfeld-Akademie for staff training.

The core technology stack combines people-intensive field operations with proprietary in-house developed machinery — notably the GLK 90 deep loosener (Schlitzlockerer) for soil decompaction, the MicroDrain system for greens drainage, and the Quickseeder capable of covering 5,000 square meters per hour. The firm conducts long-term research into autonomous mowing in collaboration with Hochschule Osnabrück and publishes the annual "Golfmarkt Deutschland" Golfreport as an industry data product. Quality is tracked with over 1,000 monthly assessments per course during the season, and dedicated renovation teams can perform capital works without disrupting play (1,068 greens aerified in 2015; over 3 million sqm of fairway mowed in 2017).

Sommerfeld generates revenue through four principal streams: recurring multi-year managed-service maintenance contracts (greenkeeping), project-based construction and renovation work (including bunkers, greens reconstruction, drainage, pond and bunker builds), irrigation system design/install/service with intelligent water-saving controls, and proprietary fertilizer and machinery lines some of which are sold or licensed. Pricing is custom-quoted per project or contract; no public rate cards are published. Go-to-market is direct enterprise field sales to golf club boards and operators, supplemented by industry events (DGV-Verbandstag, BVGA Golffachkongress, GCSAA Conference), the Greenletter newsletter, social channels, and professional golfer Esther Henseleit sponsorship. A modest non-golf vertical (football stadium turf at VfL Osnabrück) is being explored.
