STRI Trials

In autumn 2020 we commissioned independent scientific trials with the Sports Turf and Research Institute. The trial compared BS3882:2015 compliant topsoil Landscape20 and Sports&Turf top-dressing with a range of other predominantly high sand rootzones. The trial was aimed at giving our customers independent, scientific evidence when choosing a product for construction or topdressing projects.


With a growing pressure, to reduce water and artificial fertilisers usage, we wanted to see if the use of the inherent properties of a soil-based rootzone would be of benefit.


The trial was a randomised and replicated seeded and turfed pot trial. Comparing Landscape20 and Sports & Turf against:

  • USGA style free-draining mix (80:20 sand: peat mix)
  • Tee’s mix (70:30 sand: peat mix)
  • Sand: soil mix (80:20 sand: soil mix)
  • Clay loam soil
