Why It Matters
Closed-loop/recirculating CEA irrigation accumulates pathogens, biofilm, and salt/hardness imbalance; need a combined biocide + chelant + pH program
Solution Approach
Closed-loop/recirculating CEA irrigation accumulates pathogens, biofilm, and salt/hardness imbalance; need a combined biocide + chelant + pH program 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.
