ABSTRACT

This paper examines the influence of polyacrylamide on soil biological activity. The results of the incubation experiment conducted in the laboratory are given. Carbon dioxide gas release or soil respiration is- one of the indicators of soil biological activity. Determination of the amount of released CO2 was carried out titrimetrically. Aliquots of alkali titrated continuously throughout the experiment. The graph presents the resulting effect of introducing polyacrylamide into the soil on release of total CO2. Finally the article presents conclusions and puts the problems of further study and system analysis of application of polya-crylamide in the active soil environment.

Text

Проведение мероприятий по восстановлению и использованию деградированных и нарушенных земель - важная и сложная задача по современному освоению техногенных ландшафтов. Одной из важных проблем техногенных ландшафтов является потеря гумуса и важных элементов в процессе эрозии и дефляции. Количество питательных веществ, выносимых с жидким и твердым стоком в период летней эрозии и, дополнительно учитывая, количество элементов, смываемых твердым стоком в ранневесеннее время, достигает существенных величин. Эти потери также превосходят размеры ежегодного поступления данных соединений [4]. В ходе биологической рекультивации предусматривается ряд мероприятий по восстановлению плодородия нарушенных земель и по предотвращению эрозии и дефляции.
