Plant residues are the main source of humus and some nutrients in soils. The composting of organic waste using modifiers is a promising way to obtain high-quality organic fertilizers. Here, the effect of biochar and calcium carbonate on the abundance and taxonomic composition of bacteria and fungi in mature plant compost has been studied using metagenomic analysis. Plant materials with different initial C:N ratios—low (22, clover), medium (38, rye) and high (68, oats)—served as composting materi
