Sažetak
The experiment was conducted to investigate the effect of natural zeolite clinoptilolite on microbial stabilization of the solid fraction (SF) of pig slurry amended with zeolite and/or sawdust during 6 week storage with turning after 1 and 3 weeks. The solid fraction was obtained by mechanical separation on vibrating sieves in the first stage of aerobic pig slurry treatment. The temperatures recorded in the substrates S1-S4 (S1=control; S2=SF+2 percent zeolite; S3= SF+2 percent sawdust; S4=SF+2 percent zeolite+2 percent sawdust) showed a significant (P less than 0.001) positive effect of zeolite amendment during the first 3 weeks of storage. Plate counts of psychrophilic, mesophilic and coliform bacteria were also affected by zeolite and correspondedto the course of temperature. At the end of the experiment, fecal coliform counts were by about one order lower in the amended substrates (S2-S3) in comparison with the control (S1).
