My Story
Andrew Turnbull
Founder, SW Agronomy | Turfgrass Biostimulant Specialist | MRes, BSc (Hons.)
I am a turfgrass scientist and biostimulant specialist with over 40 years of hands-on experience of managing, researching, and innovating in the golf and sports turf industry. Starting during my early days as a greenkeeper at one of Europe's top golf courses — where I realised that "we have to do this differently"— to being a Course Manager, Construction Agronomist, College Tutor and businessman, my mission has remained clear: to help turf managers create healthier, high-performing playing surfaces using smarter, more sustainable methods.​​

My motviation for change started when I was a golf greenkeeper and spending a day spraying a pesticide, then going home and playing with my children. I realised that, even if I had showered and changed clothes, I could be spreading harmful pesticide residues around my home. I ask those who deride these efforts, "Why would we choose to do that?"
In 1999 took myself to university and achieved a BSc. (Hons), for which my Dissertation was on using compost for topdressing turfgrass surfaces, which opened up the world of soil microbes. I have progressed to study for, and achieved in 2021, a Master of Research (MRes) from the University of Nottingham, where I explored how a specific plant extract to reduce the need for supplementary lighting in sports stadia by enhancing photosynthesis.
​
In 2007, I and a friend introduced carbohydrates and microbes to the UK turfgrass market and paved the way for the current universal adoption of biostimulants and low-risk turf treatments, long before 'sustainability' was a word. As a consultant and freelance product developer I have lead product innovation and sustainability projects across Europe, Scandinavia and Central America. I have supported leading sports stadia, golf courses, and international suppliers by developing plant extract biostimulants and microbial soil treatments.
I am proud to have shaped innovations once seen as 'quack ideas' but now regularly used to manage turfgrass surfaces in the Premier League, on Open Championship venues, and in high-profile international facilities.
​
In addition to my commercial work I have contributed to industry education as a Course Tutor at Warwickshire College, from 2002 to 2007, creating and managing NVQ Level 2 & Level 3 Apprenticeships, and Higher Education programmes. I also regularly write for greenkeeping and sports turf trade press and have spoken at the BTME, SALTEX and other national events.
​
All these experiences of solving challenges, and advanced knowledge of turfgrass and soil science, has resulted in the development of my BioNutrition for Turfgrass Surfaces. I am available to help you with:
​
-
solving challenges on your turfgrass surfaces
-
advising and project managing construction schemes
-
developing and delivering staff improvement programmes.

Today, through South West Agronomy, I combine scientific expertise with practical experience to deliver innovations that solve the challenges of managing your turfgrass surfaces.
