Foliar Silicon: Potassium Silicate and Silicic Acid

Growers buy soluble silicon as potassium silicate or stabilized monosilicic/orthosilicic acid for plant-strength and abiotic-stress nutrition programs, in totes. Plant-available silicon is taken up as orthosilicic acid and deposited in cell walls, increasing tissue rigidity

Solution Approach

Growers buy soluble silicon as potassium silicate or stabilized monosilicic/orthosilicic acid for plant-strength and abiotic-stress nutrition programs, in totes. Plant-available silicon is taken up as orthosilicic acid and deposited in cell walls, increasing tissue rigidity RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Application Workflow
1
Application & Agronomic Review
Define the use (crop input, adjuvant, soil amendment, post-harvest) and the agronomic, regulatory, and tank-mix requirements.
2
Input & Grade Selection
Match the surfactant or adjuvant, nutrient source, chelate, or formulation aid to the active, water quality, and label.
3
Compatibility & Rate Trial
Confirm tank-mix compatibility, dose, and stability, and size packaging (jugs, drums, totes, bulk) to the season and logistics.
4
Field Validation
Validate efficacy and crop safety in field trials, and lock the spec and supply plan for the season.
Recommended Chemistries (4)
Potassium silicate (soluble, ag grade)
CAS 1312-76-1
Alkaline soluble silicate that supplies plant-available Si plus K; on dilution it releases orthosilicic acid for uptake
Full Details
Stabilized monosilicic / orthosilicic acid
CAS 10193-36-9
Pre-stabilized monomeric silicic acid is the directly plant-available silicon form, avoiding the high pH of bulk silicates

Sodium silicate
CAS 1344-09-8
