Enfoque de solución
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 (5)
o,o-EDDHA Fe chelate (6%)
CAS 16455-61-1
Aromatic phenolic chelator that keeps Fe(III) soluble and plant-available up to ~pH 9-11, the only common iron chelate stable on calcareous soils

EDDHSA Fe chelate
Sulfonated EDDHA analogue offering high-pH iron stability with greater water solubility for fertigation
EDDHMA Fe chelate
Methylated EDDHA iron chelate giving comparable high-pH stability for correcting lime-induced chlorosis
Tetrasodium EDTA (EDTA Na4)
CAS 64-02-8
Aminas y Amidas
Chelant
Lower-cost chelate for neutral-to-acidic soils and tank sequestration of hardness ions, but releases iron above pH 6.5-7 (already in catalog, contrast product)
Punto de fusión:300 °C (decomposes) Densidad:6.9 lb/gal /Apparent density/ Solubility: Slightly soluble in ethanol
