PERINOVA® POTASSIUM SULPHATE (SOP) first brings all the benefits of the sulfate of potash form.
It improves yield and quality of high value crops. It is a virtually chloride free potash fertilizer, with the lowest salt index of all potash fertilizers, and the only one to also supply sulfur in the sulfate form, which is the one taken up by the plants.


These exclusive combined properties of SOP ensure a better mineral nutrition, an improved photosynthesis and translocation of assimilates, an increased resistance to diseases, a better appearance and taste as well as an improved nutritional value of fruits and vegetables.
SOP doesn’t contain any nitrogen. It thus allows a better management of the nitrogen fertilization, especially for those crops which require very moderate N dressings (if at all) towards the end of their growing cycle, in order to achieve the best quality of the crop.
