Effects of sold cattle manure composting

Abstract

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 thermopilic 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.
