Grigg Brothers has proven itself to be a valuable partner in the golf and sports turf industry since 1995. Our Proven Foliar liquid and GreenSpec granular fertiliser technologies are backed by many years of independent university research and extensive field trials. We offer turf grass managers and greenkeepers sustainable fertiliser solutions with unmatched quality, performance, and compatibility.

The Grigg Brothers proprietary liquid organic chelation technology uses only naturally occurring compounds which are nutrient specific and biodegradable by plant enzymes. This ensures efficient plant uptake, ease of use, compatibility, and safety. University research shows that our Proven Foliar products are quickly and efficiently absorbed by turf grasses, limiting losses to the environment in the form of leachate or runoff. Using technologically advanced formulas helps to ensure no accumulation of toxic substances in the plant, unlike foliar fertilisers formulated with synthetic chelates like EDTA, which cannot be metabolised by the plant.

The GreenSpec granular fertiliser formulations provide fast and consistent nutrient availability and contain natural compounds that enhance soil microbiology and chemistry. These products were developed with purity in mind and do not contain any waste fillers, manures, or heavy metals. The result is an efficient nutrient delivery system with superior performance and environmental safety and optimum sustainability.
