Основная цель исследовании заключалась в определении изменения активности дегидрогеназы в зависимости от макроагрегатного состава и элементов рельефа на лесных почвах. Исследование проводилось в Коджада, город Самсун, Турция. Пробы почвы были отобраны в пяти точках исследуемого ландшафта, т. е. вершина, склон, откос 1, откос 2 и подножье склона. Методом сухого просеивания почвы были разделены на шесть фракции, в которых была определена активность дегидрогеназы. Исследования показали, что рельеф влияет на содержание макроагрегатнои фракции и активность дегидрогеназы в агрегатах. Во всех образцах почв исследуемого участка, содержание макроагрегатов, во фракциях > 6,3 мм и 2,00-4,75 мм было более высокое, чем в других фракциях. Наиболее высокои активностью дегидрогеназы обладают почвы подножии склонов. Во всех участках, за исключением склона, активность дегидрогеназы была более высокои в макроагрегатах фракции <1 мм, чем в других фракциях.

This article describes research on determining the changes dehydrogenase activity in the natural development of macro aggregates development along a slope in forest soils. This study was carried out in Kocadag, Samsun, Turkey. Four landscape positions i.e., summit, shoulder back slope and foot slope, were selected. For each landscape position, soil macro aggregates were separated into six aggregate size classes using a dry sieving method and then dehydrogenase activity was analyzed. In this research, topography influenced the macro aggregate size and dehydrogenase activity within the aggregates. At all landscape positions, the contents of macro aggregates (especially > 6.3 mm and 2.00-4.75 mm] in all soil samples were higher than other macro aggregate contents. In foot slope position, the soils had generally the higher dehydrogenase activity than the other positions at all landscape positions. In all positions, except for shoulder, dehydrogenase activity was greater macro aggregates of <1 mm than in the other macro aggregate size.
