FIELD: agriculture, in particular, evaluation of soil capacity of supplying farm crops with mineral nitrogen under sloped relief conditions.
SUBSTANCE: method involves composting soil while adding ammonium sulfate; determining content of nitrates accumulated in soil after decomposition of organic compounds. Composting procedure is carried out under natural field temperature mode conditions in bottomless vessels and at optimal moisture content mode conditions by providing periodic off-season irrigation procedures. Nitrification capacity is evaluated by ammonium nitrogen-to-nitrate nitrogen transition intensity.
EFFECT: increased information content of nitrification capacity evaluating method and wider range of usage.
