Characteristics
FERTISOL POTASSIUM formulas are produced from pure crystals, highly soluble in water and free from sodium, chlorides and carbonates, hence suitable for all irrigation systems. The very low salt content reduces sedimentation levels, which prevents nozzle clogging and tubes blockage. The high potash content is recommended for fruit set and maturing when higher potassium levels are required to improve yields’ quality. The nitrogen content in its different forms constitutes a readily mobile and long-lasting nutrition to maintain a vigorous plant with an activated metabolism for a healthy growth of all plant organs. The presence of SO3 prevents sulphur deficiencies and facilitates an efficient uptake and assimilation of nutrients, for the role it plays in the demobilisation of the mineral elements in the soil. The EDTA chelated micro-nutrients add to the formulas a complete nutritional provision for growth enhancement under high soil pH conditions and for the stimulation of biochemical interactions and activation between different nutrients.
