ВЛИЯНИЕ ГИДРОТЕРМИЧЕСКИХ УСЛОВИЙ НА ПРОЦЕССЫ АММОНИФИКАЦИИ И НИТРИФИКАЦИИ СОЕДИНЕНИЙ АЗОТА В ТОРФЯНЫХ ПОЧВАХ РАЗНЫХ СТАДИЙ ЭВОЛЮЦИИ

In agropeat, degropeat-mineral and mineral residual peat soil, in congenial hydrotermic conditions for organic compounds mineralisation (humidity 60 % and temperature 25-26 °C), the nitrification process' intensity prevail over ammonification and as a result nitrogen ammonic form turns more intensively into nitrate form and insignificantly amass in soil. And this nitrogen mineralizing ability compounds in soils 322, 312, 140 mg/kg of soil respectively.While composting soils in conditions which drift from optimal in humidity and in temperature, the ammonification process is on sufficiently high level and nitrification is suppressed in more or less degree, intensity and amount of mineralization of organic nitrogen matter dicreases. The process of organic matter mineralization in three types of soil in different hydrotermic conditions under study is similar itself, but differs in quantitative composition.
