Abstract:

The actual stage of the agricultural development impose a special attention to the microelements use besides the base fertilizers (N, P, K), in the view of obtaining of some new production superior from the quantity and quality point of view. Taking into account that a deficiency of the microelements is transmitted trough the trophic lance to the human can appear perturbation in some biological processes of great importance in the life cycle, how are: the oxido-reduction processes, the intra and extra cellular pH control, hydrolyze. In the paper are presented data regarding the establishment of the optimum conditions of PK fertilizers obtaining with microelements: the pH of the mass reaction, the electric conductance, the realizing of a maximum separation degree of the microelements ions in the view of these using like solid and liquid PK fertilizers with microelements.


Keywords: fertilisers, microelements, pH, molar ratio
