How it is applied
- Foliar spray — delivers nutrients directly to leaves for rapid effect
- Soil application — improves root-zone fertility
- Irrigation systems — compatible with drip and hydroponics for continuous feeding
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 our seaweed extract grades
Our seaweed extract is supplied in four physical forms and three fortified variants. The right grade depends on how you apply it and what you are correcting.
| Grade | Form | What distinguishes it | Usual application |
|---|---|---|---|
| Seaweed Extract Flakes | Flake | Concentrated solid; dissolves for spray or irrigation | Foliar, root irrigation, soil |
| Seaweed Extract Powder | Ultra-fine powder | Dissolves completely; also used in cosmetic formulations | Foliar, drip, hydroponics, seed treatment |
| Seaweed Extract Granules | Granule | Slowest to dissolve of the solids; strongest soil-conditioning effect | Foliar, soil treatment, hydroponics |
| Seaweed Extract Liquid | Liquid | Ready-to-dilute; alginic acid ≥ 8 g/L, K₂O ≥ 30 g/L | Foliar, drench, irrigation |
| Green Seaweed Liquid (this grade) | Liquid, two grades | Standard and high-grade variants with different NPK balance | Foliar, soil, irrigation |
| Seaweed Extract — Micronutrient Type | Powder | Fortified to ≥ 13% micronutrients for trace-element correction | Foliar, soil, hydroponics |
| Seaweed Extract — Protein Type | Powder | Fortified to ≥ 80% protein and ≥ 14% N | Foliar, drench, drip |
| Seaweed Extract — Green NPK Type | Powder | Balanced with K₂O ≥ 16% for pre-harvest quality work | Foliar, drench, fertigation |
