title: Dataset of winter wheat yields in Germany between 1958 and 2015 from N-fertilization experiments - TRIAL_SITES

description: This data set (TRIAL_SITES) is the starting point of a larger data set that contains data and information used in the study “Yield development of German winter wheat between 1958 and 2015” in the Project “Data-Meta Analysis to assess the productivity development of cultivated plants” funded by the DFG. This starting table contains geographical and environmental information about the experimental sites at which the N-fertilisation experiments were conducted. Amon other topics, this data set can be mainly used to analyse the impact of climatic changes on the development of winter wheat in Germany. The data set comprises following data: - Winter wheat (Triticum aestivum) yields and nitrogen application amounts from nitrogen fertilization experiments of variable duration (1-6 years) carried out at 43 locations across Germany, between 1958 and 2015, and found in 34 different sources in the literature. - The derived maximum yields (Ymax) and optimal nitrogen amounts (Nopt) from the nitrogen experiments, function coefficients, and statistics. - Geographical information (latitude, longitude, altitude) and other site specific information of the experimental sites (soil type, soil yield potential, mean annual temperature, mean annual precipitation, mean annual climatic water balance, soil climate region, cultivation region). - Processed phenological and climatic data for each experimental site.

title: Arable land rent price, rent proportion, and soil quality in Germany, at district level

description: Property rights play a decisive role in the target-oriented governance of soil protection within agricultural systems. The data set contains information on arable land rent prices, rent proportion and yield potential, as an indicator for soil quality, at the district level in Germany based on the main survey of the 2010 agricultural census. Data of arable land yiel potential was processed with the aim to spatially visualize the linkage and distribution in combination with arable land rent proportion and rent price. In the publication (Daedlow et al. 2018, https://doi.org/10.3390/su10082880), for which this data set was developed, the three parameters were examined for correlations and discussed with theoretical assumptions. Finally, conclusions regarding the sustainable use of soils depending on different property rights conditions were drawn.

title: Agroforestry promotes soil microbial groups

description: Samples of the upper 5-cm topsoil were taken in spring 2019 at three sites with paired agroforestry and conventional monoculture croplands. Samples within the agroforestry systems were taken in the tree row and at 1, 7, and 24 m distance in the crop row from the tree row. We quantified 13 taxonomic groups of microorganisms and 9 genes involved in N cycling (N2 fixation, nitrification, and denitrification) in soil using real-time PCR.

title: BonaRes SIGNAL: soil-N-cycling genes at Dornburg and Mariensee 2017

description: This data obtained from a paired cropland agroforestry and monoculture system near Dornburg, Germany and a paired grassland agroforestry and open grassland system near Mariensee, Germany in 2017. In each replicate plot of the agroforestry systems, soil samples were taken in the tree row as well as within the crop/grass row at distances of 1 m, 4 m, 7 m from the tree row. In the monoculture/open grassland systems, soil samples were taken in each replicate plot. N-cycling genes and soil properties were analysed as described in the methods. The study aimed to investigate i) whether agroforestry systems affect the abundance of soil-N-cycling genes and ii) if soil properties could explain the observed patterns of soil-N-cycling genes.

title: BonaRes foresight interviews 2017 - quantitative answers

description: On the basis of a literature-based foresight study, we identified drivers, trends and possible developments of soil management in Germany, from which we derive challenges and opportunities, and corresponding research needs (Techen, AK. & Helming, K. Agron. Sustain. Dev. (2017) 37: 64. https://doi.org/10.1007/s13593-017-0473-3). In this context, soil management is broadly understood, that is, far beyond tillage, as the agricultural practices that affect all soil functions. We asked 22 experts in 19 interviews to validate and supplement the results of the foresight study with us. 
	The interviewees were chosen based on the area of their expertise. Within this constraint, we considered experts who were known to us. Several of them are members of the advisory board of the BonaRes Centre. They had already been chosen for this committee because of their distinguished expertise and relevant roles for agricultural soil management. The names and affiliations of the interviewees are given in the supplemental information.
	The questionnaire had a German and an English version and contained questions with structured and quantified answers as well as open questions. 
	The interviews were partly conducted via telephone, partly face-to-face. The interviews were recorded. They were then transcribed, partly by us, partly by a transcription company. The quantitative statements were entered into the data table directly from the filled questionnaires. For the verbal comments, variables were constructed which for the most part are commentaries to quantitative questions. The verbal statements were entered from the transcripts into the data table, assigned to the respective variables.

title: BonaRes SIGNAL, Site: Reiffenhausen, biomass production 2016/2017

description: This data was collected in cropland agroforestry (=alley cropping of poplar clone max 1 with summer barley) at Reiffenhausen/Germany during 2016/2017.  Data was taken at 4 replicates each in the tree strip component of agroforestry, the cropland of component of agroforestry at different distances from the tree strip (=1m, 4m, 7m) and at the monoculture. We measured productivity as dry mass of harvested (plot combine) corn and straw as well as above-ground biomass production of trees (calculated with allometric equations of the form dry mass = a x dbh^b and adjusted to a subsample of 25 harvested trees within the observed dbh range) plus leaf litter in the tree strip (taken from one litter trap per replicate).

title: BonaRes SIGNAL, Site: Mariensee and Reiffenhausen, plant nutrient availability (N,P,K,Ca,Mg), Nutrient response efficiency (N,P,K,Ca,Mg), Nutrient uptake (N,P,K,Ca,Mg), Nutrient uptake and use efficiency (N,P,K,Ca,Mg)

description: This data was collected in grassland agroforestry (=alley cropping of willow strips and grassland strips) at Reiffenhausen/Germany ((Salix schwerinii x S. viminalis) x S. viminalis and grass-clover mixture) and Mariensee/Germany (S. schwerinii x S. viminalis and grassland mixture consisting of Lolium perenne, Festuca pratensis, Phleum pratense, Poa pratensis) during 2016. Data was taken at 3 replicates (Mariensee)/ 4 replicates (Reiffenhausen) each in the tree strip component (=Tree) of agroforestry, the grassland component of agroforestry at different distances from the tree strip (1m, 4m, 7m) and at the conventional grassland (=Conv) adjacent to grassland agroforestry. Components of agroforestry were also weighted according to their field size representation (=AF_weight Reiffenhausen: Tree 0.46, 1m 0.31, 4m 0.23; Mariensee Tree 0.35, 1m 0.23, 4m 0.21, 7m 0.21). We measured plant-available nitrogen with the buried bag method (Page et al. 1994 Methods of soil analysis), plant-available phosphorus with resin+bicarbonate extraction (Cross and Schlesinger 1995 Geoderma), plant-available Ca, Mg, K by percolation of soil with unbuffered 1 mol L-1 NH4Cl followed by analysis of percolate with inductively coupled plasma-atomic emission spectrometer (ICP-AES; iCAP 6300 Duo VIEW ICP Spectrometer, Thermo Fischer Scientific GmbH, Dreieich, Germany), nutrient response efficiency (NRE) as productivity divided by plant available nutrient (Bridgham et al. 1995 American Naturalist; productivity data provided by Malec et al. for Reiffenhausen and Swieter et al for Mariensee). Plant uptake was calculated as productivity x plant nutrient concentrations (C/N analyzer (Elementar Vario El; Elementar Analysis Systems GmbH, Hanau, Germany) or ICP); Nutrient uptake efficiency as nutrient uptake (productivity x plant nutrient concentrations) / available nutrient; Nutrient use efficiency as productivity/ plant nutrient uptake (productivity x plant nutrient concentrations).

title: Raw data P-XANES measurements

description: Acceptability of novel bone char fertilizers depends on their P release but reactions at bone char surfaces and impacts to soil P speciation are insufficiently known. By sequential fractionation and synchrotron-based X-ray absorption near edge structure (XANES) spectroscopy we investigated whether and how the chemical composition of bone char particles has been altered in soil and, consequently, has affected the P speciation of amended soils. Therefore, two different kinds of bone char particles (BC, produced by pyrolysis of degreased animal bone chips at 800 ºC and BCplus, a BC enriched with reduced sulfur compounds) were manually separated from the soil at the end of two different experiments: “incubation-leaching” and “ryegrass cultivation”. Sequential P-fractionation of amended soils showed P-enrichment in all fractions as compared to the control. The most P increase between all treatments significantly occurred in the NaOH-P and resin-P fractions in response to BCplus application in both, incubation-leaching and ryegrass cultivation experiments. This increase of the readily available P fraction in BCplus treated soils was confirmed by linear combination fitting (LCF) analysis on P K-edge XANES spectra of BCs particles and amended soils. The proportion of Ca-hydroxyapatite decreased, whereas the proportion of CaHPO4 increased in BCplus particles after amended soils had been incubated and leached and cropped by ryegrass. Based on P-XANES speciation as determined by LCF analysis, the proportion of inorganic Ca(H2PO4)2 increased in amended soils after BCplus application. These results indicated that soil amendment with BCplus particles leads to elevated P concentration and maintains more soluble P species than BC particles even after 230-days of ryegrass cultivation.

title: Bee diversity in island-like habitats (kettle holes) to assess connectivity in agricultural landscapes - Part 1 of data collection

description: 	During June and July of 2017, wild bees were collected using color traps (blue, yellow and white pans) in small water bodies called kettle holes embedded in agricultural landscapes in the north of Germany. After all wild bees were identified to species level, from a subset of samples we measured the Intertegular distance ITD (distance between the wings) as body size and searched for functional traits regarding sociality (solitary, eusocial, parasitic) nesting type (below- or aboveground), and lecty (poly- or oligolectic). In addition, biotic and abiotic characteristics of these kettle holes were recorded to evaluate how they affect wild bee diversity. These factors included size of the kettle hole, the degree of isolation (number of neighboring kettle holes at different distances), percentage of flowering species and total of plant species (herbs and woody plants). We tested the effect of all these factors on wild bee abundance and bee species richness, as well on body size and functional traits. - Applied Methods for sampling and identification: Collection of individuals using colour traps. One trap had 6 coloured plastic containers (white, blue and yellow) placed in three levels randomly. Water with some drops of soap was added to each container and traps were place in each kettle hole during 48 hours. A total of 4 traps were set up in each kettle hole and a total of 36 kettle holes were studied. After 2 days insects trapped in the water were collected without differentiating the colour of the plastic container. Bee individuals were separated and taken to the lab for further preparation and identification. - Bee specimens were pinned and dried at room temperature. Individuals were identified until species level by specialists K. Rupik from Bielefeld University and C. Saure at the Natural History Museum in Berlin. Information about functional traits regarding sociality, lecty and nesting were compiled from the literature with the final list of species. Body size was characterized as intertegular distance (distance between wings) measured in a subset of randomly selected individuals per species.

title: Sharing motor plans while acting jointly: a TMS study

description: When acting together, we may represent not only our own individual goals but also a collective goal. Although behavioural evidence suggests that agents' motor plans might be related to collective goals, direct neurophysiological evidence of whether collective goals are motorically represented is still scarce. The aim of the present transcranial magnetic stimulation (TMS) study is to begin to fill this gap. A participant and a confederate were asked to sequentially perform a two-choice reaction time task by acting on pressure sensors. In their own turn, they saw a cue indicating whether to lift their fingers from (or to press them on) a pressure sensor to shoot a ball across the screen as fast as possible. The confederate responded with the right hand, the participant with the left hand. While the confederate acted on the sensor, the participant's motor evoked potentials (MEPs) were collected from the right Extensor Carpi Ulnaris. If participants represent their own and the confederate's actions as being directed to a collective goal, MEPs amplitude should be modulated according to the action the confederate should perform. To test this conjecture, we contrasted three conditions: a Joint condition, in which both players worked together with their collective goal being to shoot the ball to get it to a common target, a Parallel condition, in which the players performed exactly the same task but received independent outcomes for their performance, and a Competitive condition, in which the outcome of the game still depended on the other player performance, but without the collective goal feature. Results showed no MEPs modulation according to confederate's action in the Joint condition. Post-hoc exploratory analyses both provide some hints about this negative finding and also suggest possible improvements (i.e. adopting a different dependent variable, avoiding task-switching between conditions) for testing our hypothesis that collective goal can be represented motorically.

title: Softening of processed Plant Virus infected Cucumis sativus Fruits

description: Texture softening of pickled cucumbers does not meet consumer’s quality expectations and leads to economic losses. The factor(s) triggering that phenomenon is still unknown. We investigated the importance of plant viruses such as Cucumber green mottle mosaic tobamovirus (CGMMV) and Zucchini yellow mosaic potyvirus (ZYMV) in the context of softening of pickles. All fruits were pasteurized, separately stored in jars and subjected to texture measurements after four, six and 12 months.  We conclude, that plant viruses could have a considerable influence on the firmness and crunchiness of pickled cucumbers after pasteurization.
