In a pot experiment, composting derno-podzolic soil with rye straw and particularly with straw + N fertilizers increased the total-C content of the soil compared with soil composted without straw. Composting for 220 days without straw increased the content of humic acids somewhat and decreased the C in the residue. Composting with straw increased the humic acids and the C in the residue. Composting with straw decreased the degree of polymerization of the humic acids.
