In order to obtain effective mineral fertilizer, different mixtures of phosphate rock (PR) with natural clinoptilolite (Cp) and NH4+ saturated clinoptilolite (NH4-Cp) were subjected to soft mechanical activation. Mean concentrations of P released from mechanically activated (MA) substrates, MACp/PR and MANH(4)-Cp/PR, ranged between 281-3.19 mg L-1 and 202-774 mg L-1, respectively. These are 10 to 15 times higher P concentrations than those released from the corresponding non-activated mixtures. Solution Ca2+, K+, Na+ and Mg2+ concentrations varied according to the composition of the mixtures and the contact time between the two minerals within their optimal values required for plant growth. The obtained results suggest that the efficiency of the NH4-Cp/PR mixtures can be significantly increased by the proposed mechanical activation. Influence of process parameters on the observed concentrations of nutrients was shown using multivariate statistics. The highest fertilization potential de...monstrated MANH(4)-Cp/PR mixture with the largest NH4-Cp share and the longest proposed mixing time.
