Why It Matters
Fertigation and foliar-feed operations source fully soluble N-P-K salts by the tote and truckload. These crystalline salts dissolve completely without residue, delivering precise nutrient ratios through drip and injector systems
Solution Approach
Fertigation and foliar-feed operations source fully soluble N-P-K salts by the tote and truckload. These crystalline salts dissolve completely without residue, delivering precise nutrient ratios through drip and injector systems 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.
