Development of some groups of microorganisms in liquid cattle manure and farmyard manure during their fermentation.
The development of meso- and thermophilic microorganisms proceeded more strongly in the examined farmyard manure than in the liquid cattle manure. The most vigorous proliferation of mesophilic bacteria and fungi was found in both dungs during the first weeks of fermentation. Relatively greater numbers of mesophilic actinomycetes were noticed in the later experimental period. Compared to mesophilic microoganisms, thermophilic ones were less numerous and quantitatively changeable in the tested dungs. In contrast to the farmyard manure, in the liqued dung thermophilic actinomycetes did not occur at all. After 3 monts of the experiment the Coliform titre decreased to 101 in the liquid manure, but to 104 in the farmyard manure.
