Product Type
Ecklonia maxima seaweed extract biostimulant and root promoter
MARE KELP
Ecklonia maxima seaweed biostimulant with natural auxins and cytokinins for rooting, fruit set, fruit growth, nutrient uptake and stress support.
MARE KELP is a natural metabolic biostimulant and root promoter obtained from Ecklonia maxima kelp seaweed. Its formulation contains seaweed extract together with naturally occurring auxins, cytokinins and folic acid.
The source highlights its high auxin-to-cytokinin ratio and its content of polysaccharides, alginic acid, mannitol and naturally occurring micronutrients. It is designed to stimulate new root growth points, support nutrient uptake and contribute to fruit set, fruit development and post-harvest quality.
For programmes that combine Ecklonia maxima seaweed biostimulation with NPK and silicon nutrition, see SIL MARE NPK.

- Supports rooting, fruit set and crop yield.
How it works / Technical advantages
MARE KELP is derived from Ecklonia maxima and is characterized by a high auxin-cytokinin ratio. The source links this hormonal balance with stimulation of new root growth points and the formation of new root hairs.
The source further explains that root-tip cytokinin synthesis supports plant growth and fruit size, while exogenous auxins support calcium movement to the fruit, contributing to fruit firmness and post-harvest life. The formulation has a density of 1.05 and a pH of 4.4 in a 10% solution.
The datasheet also states that the product is allowed in ecological agriculture under Regulations EC 834/2007, 889/2008 and 673/2016.
Application rates and timing
Application Guidance: Use the crop-specific foliar programmes below. The datasheet also identifies MARE KELP for soil application, but it does not provide a separate soil rate, so no soil dosage is inferred.
Foliar application
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| Citrus | 1st: at the beginning of sprouting · 2nd: fruit fattening | 300-500 cc/ha | Two documented application timings. |
| Corn, soybeans and cereals | 20-25 days after emergence | 150-200 cc/ha | |
| Potato | 1st: at 6-10 leaves, when tubering starts · 2nd: 15 days after the first application | 150-250 cc/ha | Two documented application timings. |
| Rice | At the crop stage described in the source as 'the time of the godson' | 250-300 cc/ha | The source wording for the exact rice growth stage is unclear; the stated objective is to increase grain production. |
| Strawberries | 1st: flowering · 2nd: flowering / fruit fattening | 300 cc/ha | Two documented application timings. |
| Stone fruits and table grapes | 1st: pre-flowering · 2nd: fruit fattening | 300-400 cc/ha | Two documented application timings. |
| Sugar beet, cotton and other industrial crops | Pre-flowering or at the 6-10 leaf stage | 150-250 cc/ha | 1 application. |
| Sunflower | 4-6 leaf stage | 300 cc/ha | 1 application. |
| Tobacco | 1st: at transplanting · 2nd: 15 days after the first application | 200 cc/ha | The source explicitly identifies the second treatment as a foliar application. |
| Pepper, cucumber, eggplant, melon and watermelon | 1st: at 10-15% open flowers · 2nd: 2-3 weeks after the first application | 300-400 cc/ha | Two documented application timings. |
| Tropical fruits: banana and pineapple | 1st: flowering · 2nd: fruit fattening | 300-400 cc/ha | Two documented application timings. |
| Industrial tomato | 1st: beginning of flowering · 2nd: when 20-30% fruit set · optional 3rd: 2-3 weeks later | 300 cc/ha | The third application is optional. |
| Long-life tomato | When 20-30% of flowers are open | 400 cc/ha |
