FIELD: agricultural techniques.
SUBSTANCE: invention is intended for use when growing agricultural crops under closed and open land conditions as well as when performing restoration and enrichment exhausted lands. Artificial soil contains high moisture-absorbing material and a biologically active substance, the former being any-type peat of any decomposition degree and the latter nontoxic wood-origin carbon black at peat-to-carbon black volume ratio (40-60):100.
EFFECT: increased efficiency of artificial soil due to utilization of natural environmentally pure products.
