Rate of Pedogenic Carbonate Accumulation in Canadian Prairies

Междисциплинарная научно-образовательная школа Московского университета «Будущее планеты и глобальные изменения окружающей среды» приглашает на научный семинар. Тема семинара: «Скорость накопления педогенных карбонатов в канадских прериях»/ Rate of Pedogenic Carbonate Accumulation in Canadian Prairies Лектор: Prof. Dr. Ahmet Ruhi Mermut Семинар состоится 28 февраля в 17:00 мск Changes in the soil environment influence organic and inorganic C contents and 13C values of soil C across a landscape. The objective of this study was to examine relationships among landscape elements, soil properties, and storage of organic and inorganic C using stable isotope geochemistry. A hummocky landscape, typical of 38 % of Saskatchewan’s land, with glacial till parent material under native grassland was studied. Organic C content of A horizons ranges between 20 to 98 g kg-1. Both extremes occur in level positions of the south-facing and north-facing slopes. The lowest d13C value of organic C (-29.6‰) was measured in a depre
