abstract:
In model experiment the redox potential (Eh) and redox resistance of 23 samples from eroded loess soils in a small catchment of the Ciemięga river were examined. The experiment was carried out in fixed conditions of soil samples flooded with water and incubated at 5, 10 and 20oC for 60 days. During this time measurements of Eh were made and indicators of soil redox resistance t300 and t400 were calculated. The results obtained show a significant differentiation or tendencies in the examined values which depended on the localization of soil sampling within the catchment and on the temperature and time of soil incubation. Indicators of soil redox conditions appeared to be sensitive enough to show their differentiation in such homogenous soils like those formed from loess deposits.
