How it is applied
- Soil drenching — enriches the root zone and nutrient availability
- Foliar spray — direct delivery to leaves
- Hydroponics — compatible with soilless systems
Rate guidance: the rate depends on crop, growth stage and whether you spray, drench or apply to soil. Tell us the crop and the application method you use and we will send the rate for this grade.
Choosing between the fulvic and potassium fulvate grades
Humic acid improves soil structure; fulvic acid is the low molecular weight fraction that chelates nutrients. The ratio between them is the main difference between these four grades.
| Grade | Form | Declared acid content | K₂O | Where it fits |
|---|---|---|---|---|
| Fulvic Acid Powder | Powder | Fulvic acid powder, pH 4.0–5.0 | — | Nutrient chelation and foliar uptake |
| Potassium Fulvate Powder | Powder | Humic ≥ 70% · Fulvic ≥ 5% | ≥ 12% | Highest humic share; soil conditioning |
| Potassium Fulvate Flakes | Flake | Humic ≥ 60% · Fulvic ≥ 30% | ≥ 12% | Balanced humic and fulvic in a solid form |
| Potassium Fulvate Granules (this grade) | Granule | Humic ≥ 55% · Fulvic ≥ 50% | 10–12% | Highest fulvic share; granular handling |
