PQ Corporation® AgSil® 16H, 0-0-32, Potassium Silicate, Powdered Fertilizer (50 lbs.)

PQ Corporation® AgSil® 16H, 0-0-32, Potassium Silicate, Powdered Fertilizer, Soluble Silicate for Agriculture, Foliar and Soil Available Bionutrient (50 lbs.)

AgSil® 16H is a soluble form of potassium silicate providing the plant a 100% available source of silicon and potassium that are essential for optimum plant growth and health. Potassium Silicate strengthens the plant’s internal processes and external defenses. AgSil 16H low salt index makes it extremely safe to all crops including sensitive crops. AgSil applied in the soil or foliar aids the plant during periods of drought, extreme temperatures, cold, frost, heat stress, salinity and mineral toxicity (Al,Cd,As,Mn,Fe) and other abiotic stresses. AgSil 16H activates the plants immune system helping it to resist against foliar and soil diseases caused by fungi, bacteria, nematodes, viruses and other biotic stresses. Based on the crop, AgSil 16H should be applied as a foliar spray or to the soil using ground equipment or irrigation systems. AgSil 16H can be incorporated into most spray tank mixes.

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

AgSil products provide plants with silicon, an often overlooked nutrient that helps plants’ deal with stress, temperature fluctuations, drought, salinity and metal toxicity.

• Potassium silicate – Silicate is an important nutrient in plant cell wall structures.
• Helps plants to resist toxicity from phosphorous, manganese, aluminum and iron and increases tolerance to salt.
• AgSil improves leaf erectness, and improves photosynthesis efficiency. It provides resistance to mineral stress, decreases climate stress, improves strength, and increases growth and yield.
• Potassium Silicate (AgSil) is a very sensitive to pH in tank solutions.  At pH of 6 it will polymerize (gel) and can be very difficult to work with if it gets to that stage.  When first beginning to use this product we recommend keeping your spray tank water above 7 or below 5 in order to avoid any problems with this material.
• Caution: Always add AgSil 16H first to the spray tank water. A jar test is recommended to test compatibility when new or unfamiliar tank mix combinations are used. 

GENERAL USE RECOMMENDATIONS FOR AgSil 16H

Boost the health of row crops, vine crops, turf & ornamentals, greenhouse, and hydroponically grown plants with a potassium silicate bionutrient supplement.

• GROUND APPLICATIONS: Apply 1 to 3 pounds per acre in sufficient water for thorough spray coverage.
• AERIAL APPLICATIONS: Apply 1 to 3 pounds per acre in minimum of 5 gallons of water per acre.
• IRRIGATION Applications (Sprinkler, Drip, Pivot): Apply 2 to 5 pounds per acre through irrigation system.

Application and Rate Instructions:

• TURFGRASS and SOD: Apply 1 to 2 ounces per 1000 sq. ft. every 7 to 14 days. If turf is under stress application interval can be increased to achieve desired result.
• ORNAMENTALS, NURSERY, GREENHOUSE: Apply 1 to 2 pounds per 100 gallons of water.
• HYDROPONICS SOLUTIONS: Add 2.5 to 5 ounces per 100 gal of water. Resulting mixture should then be buffered to the optimum pH for nutrient solution and specific crop feeding.
• VEGETABLES: Apply 1 to 3 pounds per acre. For best results apply a minimum of 3 applications.
• POTATO and other TUBER CROPS: Apply 1 to 3 pounds per acre from planting to defoliation for plant health and to aid in skin set and sizing.
• VINES, TREE NUTS, FRUIT TREES: Apply 1 to 5 pounds per acre. First application at pre-bloom. For best results apply a minimum of 3 applications.
• BUSHBERRY AND CANEBERRY: Apply1 to 3 pounds per acre. First application at pre-bloom.
• ROW CROPS: Apply 1 to 3 pounds per acre. Higher rates or more frequent applications may be required to correct deficiencies.
• SUGARCANE and RICE: Apply 2 to 5 pounds per acre. For best results apply a minimum of 2-3 applications. Apply at 28 to 42 day intervals. Higher rates or more frequent applications may be required to correct deficiencies.
• SOIL APPLICATIONS: May be made pre-plant, side dress or in irrigation at 2 to 5 pounds per acre.

About Potasium Silicate Manufacturing Process

Potassium silicate from PQ Corporation, a Certis Biologicals Company, is a specialty product that can be used as a beneficial substance for plants in agriculture.

Potassium silicate by PQ Corporation is produced through a furnace process where silicon dioxide (silica sand) is fused with potassium carbonate (potash) in a furnace.  This process allows for ratios of silica (SiO2) to alkali (a base that dissolves in water) from 1.6 to 2.5. Glass lumps or flakes are produced that can be sold as is or dissolved in water to produce potassium silicate solutions.
