MASTER®

COMPLETELY AND INSTANTLY SOLUBLE MICROCRYSTALLINE FERTIGATORS

GENERAL INFORMATION

Due to its prompt solubility, MASTER can be used even with the most sophisticated irrigation
equipment. These products are Sodium, Chlorine and Carbonates-free; they contain EDTA
chelated microelements (Zn, Cu, Mn) and they are coloured, so the solution acts as a tracer.

DIRECTIONS

 FERTIGATION
0.5-1.5 kg/1000 m2 per day.
In case fertigations are not performed on a daily basis, the dosage must be increased in proportion to the number of days elapsing between one application and the other
(e.g. for fertigations at three-day intervals, the daily dosage must be multiplied by three.)


The direction for use should be considered as general recommendations. When in doubt as how to maximize the efficacy of the product
according to the various edaphic conditions, we suggest you contact the Valagro Technical Office.
