Potassium and phosphorus fertiliser which benefits healthy turf growth.
TourTurf® HPK High PK is a high-end liquid fertiliser based on potassium and phosphorus, seaweed extract, humic acids and an aromatic plant extract. Presently, TourTurf® HPK High PK is only sold outside of Europe due to its valuable phosphite formulation. TourTurf® HPK is a brilliant tank mix partner and is highly efficient to help prevent the commonly known turf grass diseases.

Plants suffering from phosphorus deficiency use water less efficiently, are susceptible to growth suppression, less tolerant of cold temperatures and take longer to root. 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.

Rootzones normally have phosphorus reserves, but for it to be taken up by the plant it must first be dissolved in the soil water. However, phosphorus is relatively insoluble in water. This, along with other factors, e.g., pH, moisture levels and oxygen supply, results in a lack of available phosphorus in the rootzone. High PK provides the solution to this problem.

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, which makes it immediately available to turf and gives the plant an extra benefit under all conditions.

Benefits of TourTurf® HPK:

• Readily available source of Phosphorus, ensuring rapid uptake into the plant
• With Seaweed Extract and Humic acids for extra stress relief
• Provides the greatest plant strength possible in times of high disease pressure
• Gives the desired colour and growth at low temperatures
• For all types of established turfgrass and newly seeded turf

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.

Phosphite (as a Phosphorus source) which is present in TourTurf® High PK has one less oxygen molecule than normal Phosphate and so has a higher degree of solubility and mobility. This unique characteristic permits phosphate to be readily absorbed by the leaves and root system. Once absorbed it undergoes oxidation resulting in a release ofPhosphorus. By using phosphite, turf develops more root growth and more vigorous leaf growth and provides the extra benefit of greater stress tolerance.

Seaweed extract and Humic acids for stress reduction.
Under normal conditions plants are able to make their own Amino Acids which can then be combined to form proteins, though energy is required for the process.

However, in stress conditions, there is a greater demand for Amino Acids than the plant can supply. Therefore we have added Seaweed extract and Humic acids to TourTurf® HPK.

By applying Seaweed extract and Humic acids in these situations there is a resulting saving in energy resources which enables them to be channelled into the essential plant processes. This results in a more healthy and vigorous turf which enables the plant to be more able to overcome periods of stress.
