Compost production from natural solid cattle manure, as a mixture of
excrements and wheat straw, is relatively new process in our agriculture. In this paper
are investigated possibilities and effects of this kind of treatment of the organic
fertilizers. Those fertilizers in its natural shape are significant problems on our farms.
Introduction of the method of composting, considering all the circumstances, is the most
acceptable solution for our large-scale farms.
The method of aerobical treatment has been applied during the composting of the
natural raw manure. Additional decrement of the process duration was achieved by using
of a new variety of thermophilic microorganisms. During the treatment were observed
the changes of the basic parameters, such as: temperature, weight, density, organic dry
matter, porosity, pH value, N content and C:N ratio in composted mass. Proizvodnja komposta od svežeg goveđeg stajnjaka mešavine čvrste faze
izlučevina i slame strnih žita je novina na našim prostorima. U radu su razmatrane
mogućnosti i efekti tog vida nege organskih đubriva, koji inače u svom naturalnom
obliku predstavljaju izuzetno veliki problem na našim farmama. Uvođenje postupka
kompostiranja, kao načina za rešavanje problema koje donosi stajnjak, je jedno od
najprihvatljivijih rešenja za naše velike farme, ako se uzmu u obzir sve okolnosti.
U postupku kompostiranja, korišćena je metoda aerobne nege sirove mase stajnjaka.
Urađen je i novi vid skraćenja vremena nege uz korišćenje novog soja termofilnih
mikroorganizama. U toku nege praćene su promene osnovnih proizvodnih parametara,
kao što su: temperaturne promene, promena mase, srednje gustine, organske suve
materije, poroznost, pH faktor, sadržaj N u kompostiranoj masi i odnos C:N..
