The product is stable under ordinary temperatures and pressures. Store at 4°C - 25°C. In case of spillage collect with sawdust and/or sand.
CHARACTERISTICS:
NP 4-25 is an acidifying product that performs various functions: it changes the pH value of the nutrient solutions, it improves the adhesiveness and delivery of the formulation; it promotes the nutrient uptake by the plant tissues, lowering the surface tension; it cleanses, favoring washing of honeydew and fertirrigation equipment. NP 4-25 also supplies nitrogen and phosphorus in case of nutrients deficiency.
DOSE RATES AND CONDITIONS OF USE:
Mix NP 4-25 with water until the desired pH is reached. Compare the color of the solution with that of the color scale shown on the label to check the pH value.
Acidifying action: for waters with a pH of 7.5-8, roughly 70-90 g/hl or 100-120 g/hl are recommended to reach a pH of 6-6.5 or 5-5.5 respectively.
Surfactant action: 20-30 g / hl.
Detergent action: to wash the fertirrigation systems and leaves from honeydew, distribute 100 g / hl.
Nutritional action: foliar application: 150-200 g / hl fertirrigation: 2-2.5 kg / ha
