title: Results of two alfalfa pot experiments designed to evaluate the precision and accuracy of closed chamber based CO2 exchange measurements affected by light-inhibited leaf respiration

description: Agricultural landscapes represent amajor component in the global carbon (C) cycle. Especially their behavior asCO2 sources or sinks is still under debate. In 2009 a long-term,interdisciplinary field experiment (CarboZALF-D) was established, toquantify all C fluxes at characteristic soil-plant-systems. Our researchfocused on the feedbacks of soil erosion on C fluxes, C balances and relateddrivers. Therefore, experimental plots were designed in a way to represent afull gradient of soil erosion: non-eroded, strongly eroded, extremelyeroded, and depositional soils. Here, we present data on basic physical andchemical soil properties, weather (incl. rainfall chemistry), treatments(farming practice), and crops (incl. LAI dynamics, biomass, yields,nutrients) of four representative plots over a seven-year period(2010-2016). Comprehensive scientific publications on complex interactionsin the soil-plant-atmosphere system are listed below.

title: Applicability of a novel robotic chamber system to study the spatio-temporal dynamics of agricultural CO2 exchanges

description: Current approaches to measure and quantify CO2 flux dynamics of agricultural landscapes e.g., eddy covariance, manual and automatic chamber systems have limitations in either accounting for small scale spatial heterogeneity (eddy covariance and automatic chambers) or short-term temporal variability (manual chambers). Although automatic chambers are in principle capable to detect small-scale spatial differences of CO2 flux dynamics in a sufficient temporal resolution, they are usually limited to only a few spatial repetitions. To overcome these limitations, a novel robotic chamber system for CO2 gas exchange measurements was developed which is capable to detect short term temporal dynamics and small scale spatial heterogeneity. This datasets contains data of weather conditions, measured CO2 flux(Net Ecosystem Exchange - NEE and ecosystem respiration - Reco) and modelled CO2 exchange obtained from the measurements that were conducted from 08/07/2019 to 9/09/2019 for spring barley within the hummocky ground moraine landscape of northeastern Germany (CarboZALF-D). The soil and erosion stages of the study area are classified as Calcaric Regosol (RZ; extremely eroded), Nudiargic Luvisol (eLL; strongly eroded) and Calcic Luvisol (LL; non-eroded).

title: Data set with high temporal resolution for winter wheat grown under rainfed and irrigated conditions for agro-ecosystem modelling

description: Detailed measurements on soil, plant and atmosphere are required for the development and validation of crop growth and agroecosystem models. These measurements should be available with a high temporal resolution. With the aim of creating a growth model for winter wheat, an experiment with winter wheat under integrated cultivation conditions was carried out at the intensive experimental field of the Müncheberg Research Centre for Soil Fertility, Germany, between 1979 and 1981, both with and without irrigation. Field chambers were used for daily measurements of the CO2 balance of the crop stand. The daily evaporation was measured with two different evaporation pans. The different biomass components of the winter wheat crop stand were measured in weekly intervals from April to harvest in July/August. The different biomass components were analysed in the laboratory concerning their carbon, nitrogen, phosphorus and potassium content. Based on this coherent data set, the growth model TRITSIM for winter wheat was developed at the Müncheberg Research Centre for Soil Fertility in the 1980s. TRITSIM was incorporated into the complex agroecosystem model AGROSIM-WHEAT of the Research Institute of Plant Protection Eberswalde, Germany, for the identification of optimal plant protection measures under practical field conditions. The data set presented here can also be the basis for the verification and validation of further winter wheat growth and/or agroecosystem models.

title: Data on the effect of cultivars and irrigation on soybean yield and rotational effects. Leibniz Centre for Agricultural Landscape Research (ZALF) https://www.doi.org/10.4228/ZALF.DK.103

description: This data set reports measurements and observations from a soybean cropping system experiment (2015-2018) investigating the effects of cultivars and irrigation on soybean yield and rotational effects on a subsequent cereal crop. The objective was to design novel soybean-supported cropping systems in north-eastern Germany. The data supports agronomic analyses, as well as dynamic simulation modelling and includes details on crop growth, soil characteristics and weather. In the first part of the experiment different soybean cultivars and the effect of irrigation were compared in a split block design with six replicates and the factors cultivar and irrigation during three consecutive years (2015-2017). The treatments included with and without irrigation and three early maturing soybean cultivars of maturity group 000 (cv. Merlin and cv. Sultana for feed use and cv. Protibus for human food use). Buckwheat and Narrow-leafed lupin (cv. Probor) were cultivated as references. Seeds were inoculated with HISTICK® soybean (BASF, Germany). Measurements included whole plant biomass, grain yield, one thousand seed weigh, macro nutrients (N, P, K) in the biomass and grain, and additional agronomic observations including number of plants and plant phenology. Irrigation water was applied with a sprinkler system using the Web-BEREST model (Mirschel et al., 2014) to determine the amounts and timing (data on the amounts and dates are provided). In the second part of the experiment, the pre-crop effect of soybean (without cover crop), narrow-leafed lupin (followed by turnip rape as a cover crop), and buckwheat (without cover crop) was tested on the grain yield and nutrient content in the following oat crop and on the nitrogen dynamics in the soil. Before winter (November) and in the subsequent spring (March), mineral nitrogen was measured in the soil at three depths (0-30 cm, 30-60 cm, and 60-90 cm) after the different pre-crops. A spring oat was established following the different pre-crops with 6 replicates during three consecutive years (2016-2018).

title: Allelic data from neutral markers (microsatellites) to assess genetic connectivity and diversity of four wetland plant species occurring in kettle holes.

description: Allelic data from neutral markers (microsatellites) to assess genetic connectivity and diversity of four wetland plant species occurring in kettle holes.
description: Sampling of fresh plant material: Tip of the leaves of the four species was cut using garden scissors and store in tea bags with silica gels to dry. The sampling was carried out between May and August 2016. Testing of microsatellites and building of allelic database: Dried leaf samples were taken to the laboratory for genetic assessement. 12-20 mg of dried plant material was used for DNA isolation following standard protocols of NucleoSpin 96 plant II kit (MACHEREY-NAGEL, Duren, Germany). Final DNA concentration was measured with a NanoDrop instrument (NanoDrop 1000 spectrophotometer, Peqlab). For microsatellite amplification, we used published species-specific primers. We tested different primers until achieving a minimum of 10 polymorphic markers per species in a subset of 10–15 samples. All the primer pairs that worked in the test were selected and one the forward primer of each pair was fluorescent labelled (M13-FAM). Selected marked pair of primers combined with 1 µl of DNA were used for the Polymerase Chain Reactions (PCR) using GoTaq polymerase. PCR reactions included an initial denaturation temperature of 95°C for 15 minutes, followed by 30 cycles of 94°C for 30 seconds, 60°C for 90 seconds and 72°C for 60 seconds and a final extension at 60°C for 30 minutes. Presence of microsatellites (repetitive motives) was confirmed by Sanger sequencing, and PCR products were electrophoresed using an "ABI Prism 3130xl Genetic Analyser". Afterwards, PCR products were diluted 1:20 or 1:40 according concentrations of PCR product in the agarose gel, 0.25 μl dye-labeled size standard LIZ® was added and sequenced with 3130xl Genetic Analyser (Applied Biosystems® GeneticAnalyzers). Finally, allele size scoring was performed using GeneMapper® Software with the corresponding library of “bins” and double-checked by hand. Each txt file correspond to one marker as a final result of the GeneMapper analyses. A summary data is presented in the Excel file. Analysis in the laboratory was carried out between October 2016 and December 2017.

title: Water quality and macrophyte data collected between 1994-1999 from 20 ponds in NE-Germany.

description: Abstract: The published Excel files contain the macrophyte and water quality data that where analysed in the article “How much information do we gain from multiple-year sampling in natural pond research?” The ponds were located in three regions in the intensively cultivated agricultural young moraine landscape of the state of Brandenburg, Germany. Sampling was performed once a year at the climax of the macrophyte growing season (between the end of July and the end of August) in the period from 1994 and 1999. We considered nine physicochemical water quality parameters, i.e. pH, electric conductivity, water temperature, oxygen concentration, chloride, sulphate, (ammonium) nitrogen, soluble reactive phosphorous and total phosphorus. Macrophyte species and coverage (i.e., aggregated coverage of vascular plants, Characeae and filamentous algae) growing in the inundated area of the kettle hole were mapped. Macrophyte coverage was determined in 1 to 5% percentage steps and converted to the 14-part Londo scale.

title: Script for re-creating the location of farms from non-spatial data

description: This data set contains files that are necessary for farm allocation method. They accompany the article “Re-creating the location of farms from non-spatial data: spatial allocation of single farm data” (authors: Sandra Uthes, Joachim Kiesel), submitted to the journal Agricultural Systems. The allocation methods was developed for modelling tasks requiring spatially-explicit farm locations, for example, to simulate land market decisions. Usually spatially-explicit farm data is not available for reasons of data protection and only farm typology data with aggregated spatial information (such as the share of arable land or the mean soil fertility of the farm) is at hand. Our method considers several landscape parameters for the allocation of farms, using a fine resolution (25m*25m) and introducing allocation quality indicators that allow for an assessment of the overall allocation result. The approach is implemented in the Geographical Information System (GIS) ArcInfo/ArcGIS by ESRI using the tools and script language (AML) offered by this software and operated on a BS Solares Unix Server.

title: Ecosystem functioning in urban grasslands: the role of biodiversity, abiotic and biotic novelty

description: We evaluated the relationship between biodiversity, abiotic and biotic novelty and ecosystem functioning based on in situ measurements in non-manipulated grasslands along an urbanization gradient in Berlin. We measured plant aboveground biomass (AGB), intrinsic water-use efficiency (iWUE) and 15N enrichment factor (δ15N) as proxies for biomass production, water and N cycling, respectively. The measurements were done for the whole plant community, for plants with different introduction status, plants belonging to different functional groups and two single species: Calamagrostis epigejos and Plantago lanceolata. We found that approximately one third of the forbs were alien to Berlin and theymade up around 13% of the whole community aboground biomass. Nonetheless, community aboveground biomass was positively correlated with plant-species richness . In contrast, iWUE and δ15N were mostly correlated to urban parameters associated to abiotic novelty.

title: Understanding animal movement behaviour in dynamic agricultural landscapes

description: Movement is one of the key mechanisms for animals to deal with changes within their habitats. Therefore, resource variability can impact animals’ home range formation, especially in spatially and temporally highly dynamic landscapes, such as farmland. However, the movement response to resource variability might depend on the underlying landscape structure. We investigated whether a given landscape structure affects the level of home range size adaptation in response to resource variability. We tested whether increasing resource variability forces herbivorous mammals to increase their home ranges. Hares in simple landscapes showed increasing home range sizes with increasing resource variability, whereas hares in complex landscapes did not enlarge their home range. Animals in complex landscapes have the possibility to include various landscape elements within their home ranges and are more resilient against resource variability. But animals in simple landscapes with few elements experience shortcomings when resource variability becomes high. The increase in home range size, the movement related increase in energy expenditure, and a decrease in hare abundances can have severe implications for conservation of mammals in anthropogenic landscapes. Hence, conservation management could benefit from a better knowledge about fine-scaled effects of resource variability on movement behaviour.
description: In 2014 and 2015 we collared 40 European brown hares (Lepus europaeus) with GPS-tags to record hare movements in two regions in Germany with differing landscape structures. We examined hare home range sizes in relation to resource availability and variability by using the normalized difference vegetation index (NDVI) as a proxy
