EXPRESS-METHOD OF DETERMINING NITROGEN MINERALIZATION ABILITY OF PEAT SOILS

Abstract

Method for determining nitrogen mineralization ability of peat soils is based on carrying out hydrolysis for 18 ± 0,5 hours at temperature of +27 °C in the presence of a restoring agent nitrates alloy Devarda or zinc dust mineral and organic compounds of nitrogen with as extractant solution of 0,2 M KOH at a ratio of soil: solution 1:20, measuring the concentration of ammonium nitrogen in the filtrate using photometer and processing results of the analysis by a personal computer.
