Row Field — Process Challenge

Chelatierte Mikronährstoffe, die pflanzenverfügbar bleiben

Fe/Zn/Mn/Cu fällen bei Fertigations-pH als Hydroxide/Phosphate aus und werden pflanzenunverfügbar; Chelatbildner werden benötigt, die das Metall löslich halten, sowie die Mikronährstoffsalze selbst

Lösungsansatz

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 (7)
Ethylenediaminetetraacetic Acid
CAS 60-00-4
