✦ Synopsis

Population changes in the levels of bacteria, fungi and actinomycetes during composting of spruce-bark were studied. The composting rate was determined as a function of the amount of CO 2 produced per unit of time. Composting was performed under controlled conditions of the various environmental parameters in a bench-scale composter. Temperature influence on composting was studied with a view to accelerating the process. The most favourable influence was found at a controlled temperature of 45~ Inoculation with raw bark compost had a positive effect.

The composting process found in real compost heaps was simulated in the laboratory with three treatments, nil, and urea, and cyanamide additions. Total N was separated into hydrolysable, amino acid, and amino sugar N. These fractions were related to counts of viable bacteria and spore-forming bacter
