Directions for use
Universol HW pH-control is developed for application in hard irrigation water. It is ideal for plants requiring controlled and compact growth. Thanks to the N:K ratio of 1:2, it is suitable in cases of relatively high levels of nitrogen in the irrigation water. It however can be mixed easily with other nitrogen fertilizers to create N:K ratio of 1:1. Universol Hard Water pH-control acidifies the irrigation water and neutralizes bicarbonate.
Universol HW pH-control should not be mixed in the same tank with other Universol products, other NPK fertilizers or phosphate containing fertilizers (except for phosphoric acid). To ensure that this product dissolves completely, prepare the stock solution 1-2 hours before use, stir well or use warm water.
