soluSOP® 52 organic – the ideal source for potassium and sulphur
Potassium uptake of selected crops
The dosage of soluSOP® 52 organic depends on many factors such as fertigation system (open, closed), plant type and variety, growth stage and duration of growth, yield expectation and nutrient requirement, temperature and substrates used. The following diagram indicates daily amounts of potassium (mg K2O plant-1 day-1) to be added with drip fertigation during the respective relative time of growth (0 – 100 % in five steps). This amount includes 10 % of additional potassium for root consumption (adapted from Kafkafi and Tarchitzky, 2011).
