ソリューションアプローチ
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
アミン・アミド類
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)
融点:300 °C (decomposes) 密度:6.9 lb/gal /Apparent density/ Solubility: Slightly soluble in ethanol

CAS 67-43-6
アミン・アミド類
キレート化 / 金属イオン封鎖
Mid-range chelate stable to roughly pH 7.5; bridges between EDTA and EDDHA for moderately alkaline soils
Physical Description: White to off-white solid 沸点:Decomposes 融点:219-220 ºC
