Why It Matters
Bulk input buyers source humic acid, fulvic acid and potassium humate by the tote and 25 kg bag as soil-carbon amendments and natural chelators. The carboxyl and phenolic groups on these humic substances complex metal cations, buffer soil pH and improve cation-exchange capacity
Solution Approach
Bulk input buyers source humic acid, fulvic acid and potassium humate by the tote and 25 kg bag as soil-carbon amendments and natural chelators. The carboxyl and phenolic groups on these humic substances complex metal cations, buffer soil pH and improve cation-exchange capacity 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 (4)
Humic Acid (UVCB)
CAS 1415-93-6
Specialty Additives
Conditioning
Leonardite-derived humic acid carries carboxyl/phenolic sites that chelate Fe, Zn and other cations and raise soil cation-exchange capacity
Full Details
Fulvic acid (ag-grade /)
Lower-molecular-weight, fully water-soluble humic fraction; its high carboxyl density makes it an effective metal-cation complexer across a wide pH range
Full Details
Potassium humate
CAS 68514-28-3
Soil amendment
Potassium salt of humic acid that dissolves readily for fertigation and supplies both K and humic chelation function
Full Details
Sodium humate
CAS 68131-04-4
Soil amendment
Water-soluble humate for liquid blends, providing the same carboxyl/phenolic chelation and pH-buffering as solid humic acid
