Coherent multivariable 6-year field trial data set for agro-ecosystem model verification and validation from Müncheberg experimental station

Wilfried Mirschel, Uwe Schindler, Johannes Hufnagel, Dietmar Barkusky, Sigrid Dittmar, Carola Voigt & Liane Laacke
For the intensive agro-management level a 6-year (1993-1998) multivariable data set for a 4-field crop rotation located at the Müncheberg Experimental Station with sandy soils (Eutric Cambisol) is documented in detail. Here rainfed and irrigated conditions are taken into account. The soil, weather and crop processes have been intensively monitored. The data set contains coherent soil (water, mineral nitrogen), crop (ontogenesis, biomass, yield, carbon and nitrogen content), weather (meteorological standard parameter) and management (soil tillage,...

Long-term soil hydrological data of a Pleistocene region in North-East Germany

Uwe Schindler, Dietmar Barkusky & Wilfried Mirschel
Long-term soil hydrological studies were carried out at the ZALF Muencheberg Experimental Station, located in a Pleistocene end moraine landscape in NE Germany. The effect of different tillage systems (plough and no till) was investigated. Soil water was extracted by use of suction cups for analysing the soil water nitrate concentrations. The data were used for quantifying deep drainage rates and nitrate losses as described in Schindler and Mueller (2008) and Schindler et al. (2010).

Data on moss and lichen decomposition rates and nutrient loss from old-growth and harvested high-boreal forests estimated using the litterbag and minicontainer methods

Ulrike Hagemann & Martin T. Moroni
Bryophytes and lichen are important components of many boreal forest ecosystems, making the quantification of moss and lichen decomposition rates critical to understanding the C cycle of these forests. A total of 1560 litter samples were incubated for two years (2007-2009) in six in high-boreal Labrador black spruce forests stands of different disturbance origin: three old-growth stands of wildfire origin, and three recently clearcut stands. Liter samples were incubated using two different methods (litterbags and...

Data sets of experimental study on retardation of a heavy NAPL vapor in partially saturated porous media

Simon Kleinknecht
Large-scale column experiments were performed to quantify partitioning processes responsible for the retardation of carbon disulfide (CS2) vapor in partially saturated porous media. For experiments 1-16, fine glass beads (soda-lime glass, Sigmund Lindner, Warmensteinach, Germany) were used as medium; for experiments 17-37, Geba fine sand (Quarzsande GmbH, Eferding, Austria) was used. The experiments were conducted in large, vertical columns (i.d. = 0.109 m) of 2 m length packed with different porous media. A slug of...

Six weighing lysimeters (1.5 m height; 1.0 m in diameter) with a soil surface area of 1.0 m² were installed on ground surface level at the Experimental Field Station Dedelow of the Leibniz Centre for Agricultural Landscape Research (ZALF). Water retention time series from 2012-2014 were obtained from tensiometer/MPS-1 sensors and TDR data measured in 10, 30, and 50 cm depths of six soil monoliths of lysimeters extracted from two differently managed field sites (lysimeters...

A simple method to assess the impact of sealing, headspace mixing and pressure vent on airtightness of manual closed chambers

Mathias Hoffmann, Natalia Pehle, Vytas Huth, Nicole Jurisch, Michael Sommer & Jürgen Augustin
The data set contains data from a full-factorial laboratory experiment, were three different designs and two modifications of typical manual closed chamber setups were tested for sealing integrity.

Detecting small-scale spatial heterogeneity and temporal dynamics of soil organic carbon (SOC) stocks: a comparison between automatic chamber-derived C budgets and repeated soil inventories

Mathias Hoffmann, Nicole Jurisch, Juana Garcia Alba, Elisa Albiac Borraz, Marten Schmidt, Vytas Huth, Helmut Rogasik, Helene Rieckh, Gernot Verch, Michael Sommer & Jürgen Augustin
Carbon (C) sequestration in soils plays a key role in the global C cycle. It is therefore crucial to adequately monitor dynamics in soil organic carbon (deltaSOC) stocks when aiming to reveal underlying processes and potential drivers. However, small-scale spatial (10–30m) and temporal changes in SOC stocks, particularly pronounced in arable lands, are hard to assess. The main reasons for this are limitations of the well-established methods. On the one hand, repeated soil inventories, often...

Divergent NEE balances from manual-chamber CO2 fluxes linked to different measurement and gap-filling strategies: A source for uncertainty of estimated terrestrial C sources and sinks?

Vytas Huth, Shrijana Vaidya, Mathias Hoffmann, Nicole Jurisch, Anke Günther, Laura Gundlach, Ulrike Hagemann, Lars Elsgaard & Jürgen Augustin
Manual closed-chamber measurements are commonly used to quantify annual net CO2 ecosystem exchange (NEE) in a wide range of terrestrial ecosystems. However, differences in both the acquisition and gap filling of manual closed-chamber data are large in the existing literature, complicating inter-study comparisons and meta analyses. This data set contains data of a study which compares common approaches for quantifying CO2 exchange at three methodological levels. (i) The first level included two different CO2 flux...

Maize C-dynamics are driven by soil erosion state and plant phenology rather than N-fertilization form

Madlen Pohl, Mathias Hoffmann, Nicole Jurisch, Anne-Katrin Prescher, Estefania Mendez Campa, Ulrike Hagemann, Rainer Remus, Gernot Verch, Michael Sommer & Jürgen Augustin
The dataset contains information about dynamic and seasonal net ecosystem carbon balances (NECB) for maize for the growing season 2011, measured at five sites at the “CarboZALF-D” experimental field. Measurement sites differ regarding soil type (non-eroded Albic Luvisols, extremely eroded Calcaric Regosol and depositional Endogleyic Colluvic Regosol,) and N fertilization form (100% mineral fertilizer, 50% mineral and 50% organic fertilizer, 100% organic fertilizer). Fertilization treatments were established on the Albic Luvisol. Net ecosystem CO2 exchange...

A comprehensive data set demonstrating the spatial variability of soil properties at field scale

Evelyn Wallor
The data set contains information about soil properties at 80 grid points of a 20 ha large agricultural used field in North Rhine-Westphalia. Each grid point was mapped and sampled up to the soil depth of 90 cm. Over a period of four years (1999 to 2002) soil analysis was conducted considering soil moisture and mineral nitrogen content before sowing and after harvest. Basic information about agricultural management, soil texture, soil organic carbon and annual...

A standardized conceptual and practical approach to automatically model ecosystem CO2 fluxes based on periodic closed chamber measurements

Mathias Hoffmann, Nicole Jurisch, Elisa Albiac Borraz & Jürgen Augustin
Closed chamber measurements are widely used for determining the CO2 exchange of different ecosystems. Among the chamber design and operational handling, the data processing procedure is a considerable source of uncertainty of obtained results. We developed a standardized automatic dataprocessing algorithm, based on the statistical computing environment R, which (i) calculates CO2 fluxes measured by closed chmabers, (ii) parameterizes temperature (Reco) and PAR (GPP) dependency models, (iii) optionally computes an adaptive temperature model, (iv) models...
