Abstract: The fertilizers play a very important roll in the plant growing and development. The fertilizers with microelements supply to the plant the needed nutritive substances, which doesn’t exist or are insufficient in soil [1]. In the present paper were studied the conditions establishment of the double pyrophosphate of zinc and potassium obtaining, respective of copper and potassium from solutions of zinc and cooper sulfate and potassium pyrophosphate. In this way was followed the variation of the mass reaction pH, electric conductance and zinc and copper separation degree, versus the molar ratio Me2+: P2O74- and versus temperature.
