Potassium Silicate

Soluble Silicate for Agriculture

AgSil potassium silicate AgSil® Potassium Silicate: Soluble Silicate for Agriculture helps plants to resist AgSil® potassium silicate offers Application of AgSil potassium silicate toxicity from phosphorous, growers these performance benefits improves leaf erectness, reduces susceptibility to lodging in grasses and manganese, aluminum in many agricultural applications: improves photosynthesis efficiency1. For and iron and increases • Provides resistance to mineral stress turf this can result in faster, healthier greens 1 and athletic fields. Row crops, vine crops, tolerance to salt . AgSil • Decreases climate stress ornamentals and hydroponically grown potassium silicate also aids • Improves strength plants can all benefit from potassium silicate in resistance to drought by • Increases growth and yield supplementation. reducing water loss, and in some cases it may increase AgSil potassium silicate provides a soluble 1-5 Approximate AgSil Potassium Silicate growth and yield . source of silicates and supplementary Application Rates potassium for plants.
