  • Osmocote is the original brand of controlled release fertilizer. First introduced in the 1960s Osmocote quickly became the very first Other companies have tried to match it but Scotts research and development has kept Osmocote Classic on the cutting edge of fertilizer technology. High-performance Osmocote Classic accurately delivers the selected balance of nitrogen phosphorous and potassium in each individual prill. Formulated for greenhouse nursery and landscaping applications Osmocote Classic gives growers unmatched control and flexibility. How Osmocote Works? Every prill consists of a water-soluble nutrient granule coated with a thin semi-permeable resin. This coating controls the release of nutrients according to changes in soil temperature. More nutrients are released during warmer active growing periods and less in cooler inactive periods. Osmocote does not contain urea. Each prill contains the optimum balance of readily absorbed Nitrogen Phosphorus and Potassium which are being released together to promote greener healthier plants.

  • Everris Sierraform GT K-Step is a revolutionising high performance micro granular fertiliser designed for use in fine turf throughout the year. The individual granules each contains conventional and slow release technology to provide a consistent and sustained release pattern. Nitrogen is the key nutrient for driving growth in a plant. Potassium ensures that your turf is even more resilient to external stresses. A sufficient quantity of Nitrogen and Potassium is released immediately after application, so that the plant can make use of it straight away. Benefits of Everris Sierraform GT K-Step: Longevity: 6-8weeks Turf Response: 7days Granule Dispersal: 2-3days Active at lower temperatures. Slow release Nitrogen and Potassium for sustained performance Even spread at an ultra-low rate applications (20g/m²) Granules break down and disperse rapidly Low MU content for quick reaction in cooler conditions. Encourages healthy balanced growth at start of season. Phosphate free formulation aids management of soil Phosphorus build-up. How to Apply Apply to dry foliage and irrigate after 1-2 days if no rain has fallen. Irrigation will aid dispersion and minimise any risk of mower pick-up on close mown surfaces. Try avoiding applications during frosty or drought conditions. Delay verti-cutting and/or grooming for 3 days after application to allow the granules to disperse. Nitrogen release is significantly slowed down when soil temperatures are less than 10°: Watering-in after application will minimize foot printing risk.
