Sažetak
Pig slurry solids, as one of the products of pig slurry treatment, present a risk to the environment due to their chemical composition and potential presence of pathogens and parasitic forms. Investigations were carried out to observe the effect of amending pig slurry solids with I and 2% natural zeolite (clinoptilolite) and storing the obtained substrates under anaerobic conditions or with turning during 12 weeks. We determined changes in water extractable forms of nitrogen as indicators of decomposition processes. Both doses of zeolite tested affected the release of ammonia nitrogen into the extract and 1% addition created more favourable conditions for nitrification between weeks 3 and 6 of storage.
