Grass reactions to heat and drought stress:
- Root flattening
- Leaf necrosis
- Reduced photosynthate activity
- Increased respiration: more carbohydate consumption
For turf vitalization and preparation for drought and heat stress, additional potassium applications with Kali Gazon can be recommended. Typical dry spot symptoms, so-called Localized Dry Spots (LDS) and leaf necrosis can be significantly reduced by timely
application of potassium.
Potassium also supports regeneration after drying damage has already occurred in most grass species.
High potassium with added magnesium and sulphur make Kali Gazon the stress reliever, improving turf tolerance against drought, disease and cold temperatures.
A sufficient supply of potassium reduces evaporation losses, so that irrigation can be saved. Magnesium is an essential element of chlorophyll formation and thus promotes the assimilation performance (energy intake) of turf. The high sulphur content supports protein and enzyme formation and has a pH-regulating effect on the soil.
