New name for ICL’s seaweed extract

ICL is rebranding its alkaline-extracted seaweed ‘SeaMax’ as ‘SMX’.

SMX is a highly concentrated Atlantic Ascophyllum nodosum seaweed, harvested from sustainable and renewable sources by Acadian Seaplants.

For any turf professional it is important to weigh up the evidence from product trials. Multiple trials carried out using SMX clearly demonstrate how seaweed extract improves the condition and rooting of the turf. This is because the SMX extraction process retains important and influential biochemical compounds.

As an example, research recently published in the European Turfgrass Society Proceedings showed how different Ascophyllum nodosum extraction methods produced contrasting effects on turfgrass rooting. The alkaline-extraction method (as used in the production of SMX) produced significantly greater root length and root volume than other commonly used extractions.

Independent trials also showed that SMX helped the turfgrass produce longer roots, a greater root mass and it improved the quality of growth (shoot weight), compared to competitor products or controlled conditions (using no seaweed extract). Trials that placed the turf under drought conditions, showed that the turf quality and colour improved noticeably when treated with SMX. In addition, when SMX has been included in annual nutritional programmes, the turf quality remained significantly higher throughout the autumn and in the lead up to winter.

Although the name might have changed, the formulation is the same. SMX is available as a standalone product in water soluble form (Sportsmaster WSF SMX) and in liquid form (Vitalnova SMX). It is also included as an effective dose in Sierraform GT Spring & Summer CalMag 14-0-7 as well as the new organo-mineral fertiliser Gronamic Golf 6-2-4.
