TourTurf® High PK (HPK)
With Seaweed extract, humic acids and essential plant oils for healthy turf
Healthy turf without stress!
TourTurf® High PK 0-18-12 is a liquid PK-fertiliser based on potassium and phosphorus, seaweed extract, humic acids and essential plant oil.
The product is specially designed for use on amenity turfgrass areas. Both the Potassium and the Phosphorus are in readily available, fully water-soluble forms, ensuring the turfgrass plant takes up both the P and K rapidly, especially under stress conditions.
Phosphorus is a vital element in the metabolic processes within the plant. It is an important constituent in enzymes and proteins as well as being a structural component of phosphoproteins, phospholipids and nucleic acids. Plants suffering from Phosphorus deficiency use water less efficiently, are susceptible to growth suppression, less tolerant of cold temperatures and take longer to root.
Although rootzones normally have Phosphorus reserves in them, in order for it to be taken up by the plant it must first be dissolved in the soil water surrounding roots and soil particles. However Phosphorus is relatively insoluble in water. This, along with other factors e.g. pH, moisture levels, oxygen supply and chemical reactions with other minerals to form insoluble precipitates, resulting in a lack of available phosphorus in the soil water supply.
