Proturf 21-5-6+2.5CaO+2.5MgO



  • Advantages
  • Description
  • Directions for use
  • Spreader settings
  • Rapid regreening, managed turf growth
  • Ideal for ‘waking up’ turf, even during cold weather.
  • Mini-granules with gradual nitrogen release thanks to Poly-S coating
  • Fine and homogenously coated granules: seven times greater impact per m²
  • Better distribution when applied by spreading
  • Flexibility of dose without a ‘leopard skin’ effect
  • Highly soluble: does not interfere with play
  • Fluid, easy to spread: clean, odourless, and dust-free
  • Contains magnesium: sustained colour and reduced stress.

ProTurf is a complete slow-release fertilizer, rich in nitrogen and in polyhalite. A unique natural source of potassium, magnesium, calcium and sulphur for healthy and resistant turf. A proportion of ProTurf’s nitrogen content is immediately available. The result can soon be seen even when the ground temperature is low. Thanks to the fine dust-free granules and its mode of release independent of climatic factors,

ProTurf improves the quality of your turf. Suitable for all areas mown to a height of 6 mm. ProTurf is especially recommended for fertilization during the growing period of the turf.

Directions for use
  • Apply to dry foliage.
  • Watering-in after application aids dispersion and gives a quicker initial effect.
  • Avoid applications during frosty or drought conditions.
  • Watering-in after application will minimize foot printing risk.
  • Application should be made after aeration programmes such as hollow timing, slitting and/or scarification to prevent granule damage.
