Lysimeter data Rostock: Redox potential, pH and element concentrations of pore water in 2021
The dataset contains soil pore water data from three sampling depths of three soil profiles from along a hill slope in Northern Germany. Data inform about weekly redox potential (Eh), pH and element concentrations (TC, IC, OC, TN, NH4+ -N, NO2- -N, NO3- -N, PO43- -P, total Ca, P, Fe, Al, and Mn) in filtered (0.45 µm) soil pore water samples collected in 2021. Research domain: Soil Sciences Research question: Controlled drainage may affect phosphorus mobilization in soil. To assess P mobilization at different redox conditions, three soil profiles with redoximorphic features were selected along a slight hill slope and lysimeter monoliths were collected by drilling in 2018. In 2021, lysimeters were cropped with maize. Five maize plants of each lysimeter were supplied with underfoot fertilizer (P and S) while further five plants of each lysimeter were left without fertilizer. Water levels of the monoliths were adjusted to high and low water table to mimic closed and open drainage, respectively. The redox potential (Eh) was measured in situ and pore water was sampled weekly from three different depths of the lysimeters to determine pH and the element concentrations total C, N, P, Al, Fe, Mn, and Ca as well as inorganic and organic C (DIC, DOC), NH4+-N, NO2- -N, NO3- -N and PO43- -P in solutions (0.45 µm). Thus, information about different element concentrations at different redox potentials and pH was gained over a period of about 6.5 months in 2021.
