High K

Tougher turf with TMax technology







This premium water-soluble fertilizer is ideal for preparing your turf for stress, such as wintry temperatures or drought around the corner. It features our patented TMax technology, ensuring superlative nutrient absorbency through your grass’s leaves and roots. You can combine it with a main granular fertilizer program, and it’s great to use between May and December. Thanks to its ratio of low nitrogen to high potassium, it will toughen up your turf while ensuring it doesn’t grow too fast. Its chelated iron will boost color while its nitrogen urea source will improve foliar uptake.

  • Great water-soluble pre-stress conditioner

  • Hardier turf with great color and foliar uptake

  • Good to combine with main granular fertilizer program

Recommended Rate: 15 - 60 kg/ha

Trial first on a small scale before changing the rate, or any other variables. As circumstances can differ and the application of our products is beyond our control, ICL cannot be held responsible for any adverse results.

Sportsmaster® WSF products are tank-mixable with other products within the range and H2Pro® & H2Pro® Maximize wetting agents.
 Avoid applying during frosty or drought conditions.
 Mix with Turf Mark® Extra spray pattern indicator to aid spraying, condition water and minimize spray drift (Turf Mark® is a registered trademark of BASF).
To ensure that this product dissolves completely, mix by adding the quantity required to a half-full spray tank, then agitating for 10 – 15 minutes.
Then fill the tank to full capacity with water. The water temperature will affect the dissolution rate.
The water volume used to apply Sportsmaster® WSF will affect how nutrients are taken up by the plant.
For foliar applications use low water volumes (300 – 600 l/ha) and to optimize uptake avoid high temperatures and sunny conditions.
For root uptake applications use high water volumes (600 – 1000 l/ha) and irrigate immediately afterwards for a minimum of 2 – 3 minutes, to provide the necessary water volume and to reduce the risk of turf injury.
If spilled on pavement, concrete, clothes, etc. brush off immediately as it can stain. Contains iron: do not apply in case of risk of contact with concrete, marble, stone, fabric, or swimming pools.
