Research: Grower Experiences

Observations from research projects and on-farm field trials using Canadian Wollastonite products in 2015 include:

  • Delayed onset of powdery mildew (incidence and severity) in winter squash and zucchini plants
  • Drastically reduced grub populations in turfgrass following broadcast wollastonite applications
  • Darker green, more productive alfalfa fields on Pennsylvania dairy farms when wollastonite is used instead of lime to balance pH
  • Superior short-term silicon release into soil: 5 times more than control plots and 2.5 times higher than potassium silicate
  • High silicon accumulation in cucumber leaves: triple the dry weight of control plants
  • Removal of all detectable phosphorus from greenhouse wastewater in a portable bio-filter system
