AgSil 16H, 1 pound in a re-closable plastic container

Hydroponic grade Water Soluble Potassium Silicate fertilizer.

AgSil potassium silicate offers growers these performance benefits in many agricultural applications:

• Provides resistance to mineral stress.
• Decreases climate stress.
• Improves strength.
• Increases growth and yield.

AgSil potassium silicate helps plants to resist toxicity from phosphorous, manganese, aluminum, and iron, and increases tolerance to salt (1). AgSil potassium silicate also aids in resistance to drought by reducing water loss, and in some cases it may increase growth and yield (1-5).

Application of AgSil potassium silicate improves leaf erectness, reduces susceptibility to lodging in grasses, and improves photosynthesis efficiency (1). For turf this can result in faster, healthier greens and athletic fields. Row crops, vine crops, ornamentals, and hydroponically grown plants can all benefit from potassium silicate supplementation.

This is a 1.6 weight ratio, hydrous potassium silicate powder with 32% K₂O and 52.8% SiO₂ and 14.8% H₂O.
