Green-Speed Si Fertiliser + 7% Silicate + Phosphite + Humic – 10 Litre

  • Strengthens turf blades
  • Faster ball roll / reduce ball marks
  • Helps increase resistance to disease & pests
  • Improves heat and drought stress
  • Better cut by green mowers
  • Plus humic acid to accelerate absorption

Green-Speed Si is a proprietary formula with silica, potassium phosphite, and humic acid as active ingredients. Silica hardens the leaf and helps strengthen the xylem vessels during times of high transpiration, reducing water loss. Green-Speed Si contains Potassium Phosphite which promotes turf health and increases the turf’s resistance to disease and pests. Potassium also builds carbohydrate reserves. The humic acid increases nutrient uptake through the leaf and root tissue. It is designed for foliar application on all varieties of turfgrasses on greens, tees and roughs, sports turf, lawns and ornamental grasses. Green Speed can be used in a regular maintenance program. It is best to apply Green Speed prior to heavy traffic or prior to times of heat stress.
