GRASSKEL-S is a special fertiliser with a high concentration of potassium which can be used as a source of this element in all those crops which are major consumers of potassium during their whole crop cycle, or at moments of greatest need. The use of GRASSKEL-S increases the size of the fruit, improves their colouring, taste and sugar content. It is especially indicated for bringing forward maturation and improving the organoleptic quality of the fruit.
