Optima Root is a special combination of nutrients, various biostimulants and trace elements that stimulate root growth and shoot development.

Function of the (nutrient) substances in Optima Root

Seaweed is naturally rich in alginates and complex sugars, which make seaweed resistant to the extreme conditions in the sea. The biostimulants extracted from seaweed can support other crops in plant and root growth.

The humic acids in Optima Root trigger the plant to develop roots. In addition, humic acids help to improve nutrient absorption.

The N, P, and K and the trace elements in Optima Root are essential for root development. Applying Optima Root means you optimally support root growth.


  • Accelerates the establishment of young plants.
  • Direct positive impact on root growth, and indirectly improves shoot growth.
  • Boosts crop yields.

Instructions for use
  • Shake or stir well before use.
  • Store frost free, indoors in a dark place. The product may crystallise at too cold temperatures (< 5 oC).
  • Due to residue formation, avoid foliar applications on visually attractive crops immediately prior to harvesting.
  • Not compatible with liquid calcium based products.
  • Never mix pure products together.
  • Optima Root is best applied early in the morning or in the evening to avoid strong sunlight. This minimises the risk of crop damage due to leaf burn. If the crop stays wet for longer, the nutrient uptake is improved. We recommend carrying out a trial application on a small area first, before applying to the entire plot.
  • This product has a shelf life of 3 years from the moment of production. The shelf life of the product is stated on the label. Opening the packaging in the meantime has no influence on this. As long as the guidelines for storage are followed the expiry date (BB) on the label is leading.
