Translocation of Soil Enzyme Activity by Leachates from Different Agricultural Drainage Systems

Stephan Wirth, Axel Hohn and Lothar Muller

Abstract:
Three different agricultural drainage systems located in the Northeast German lowland i.e., a free drainage of a shallow aquifer, a submerged deep drainage of a shallow aquifer and a free deep drainage were studied in order to detect evidence for translocation of enzyme activities and bacteria in percolating leachates. The activity of fluorescein diacetate (FDA) hydrolase as a measure of over-all microbial activity in the leachates was two up to three orders of magnitude lower as compared to the respective soil substrates. Enzyme activities in the leachates were almost constant throughout the year, except for a significant increase of FDA activity and cellulase activity due to a discharge by preferential flow, detected in the shallow free drainage system. FDA hydrolase was significantly but weakly correlated with chemical properties (NH4N, DOC). The population density of culturable bacteria was rather low (50 up to 300 colony-forming units mL-1 drain water) coinciding with a mostly marginal translocation of soil enzyme activity by leachates from arable drainage systems.
