RPH PLUS (NP 1-20)

NP 1-20

Solution Of Np 1-20 Fertilizers That Controls The Ph
Of The Irrigation Waters And Potentiates The Wetting
Effect Of The Phytosanitary Products

RPh PLUS is a solution based on the compound NP (nitrogen and phosphorus) that can serve as a source of these two essential macronutrients. At the same time, this product has been conceived for the application of phytosanitary products, when we use low-quality water in foliar treatments (high pH, water hardness, etc.).
Avoiding the negative effects of low-quality water on the efficiency of phytosanitary products, RPh PLUS helps phytosanitary products to enter into the plants, reducing the surface tension of the solutions that has to be sprayed. The balanced formulation of nutrients in this product creates a solution that regulates the pH in the tank of the atomizer. Regardless of the quality of water, RPh PLUS ensures the excellent efficiency of treatments.
RPh PLUS must be poured in the atomizer tank before adding other products, in order to guarantee a suitable pH when adding them to the solution. The dosage can vary depending on the pH and the hardness of the water that has to be used; quantities varying from 30 to 100 cc/hl are recommended.
