- To date, it is still unclear whether light inhibition of leaf level autotrophic respiration (LRa(d)) affects the consistency and accuracy of an ecosystems net CO2 exchange (NEE) and thus C sink or source function,
- Within two alfalfa pot experiments we investigated: (1) whether LRa(d) is inhibited by light; (2) how this influences consictency and accuracy of ecosystem respiration (Reco), gross primary production (GPP) and NEE, derived using a commonly applied gap-filling technique.

Applicability of a novel robotic chamber system to study the spatio-temporal dynamics of agricultural CO2 exchanges10.4228/ZALF.DK.143Holzendorf near Dedelow, GermanyShowOnMapView sample dataDownload complete datasetCreative Commons Attribution-NonCommercial 4.0

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).

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.

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.

Data on the effect of cultivars and irrigation on soybean yield and rotational effects10.4228/ZALF.DK.103Site Muencheberg, GermanyShowOnMapView sample dataDownload complete datasetCreative Commons Attribution 4.0
Abstract: 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).

The published Excel file contains plant structural trait data for four typical macrophyte species of kettle holes (i.e. Carex riparia, Phalaris arundinacea, Rorippa amphibia and Persicaria amphibia) that where used in the article “Allometric relationships for selected macrophytes of kettle holes in northeast Germany as a basis for efficient biomass estimation using unmanned aerial systems (UAS)”. The surveyed kettle holes are located in the AgroScapeLab Quillow, an intensively cultivated agricultural young moraine landscape 90 km north of Berlin, Germany. In total, 12 kettle holes were chosen. Within each kettle hole three habitats were selected per species. In each of the three species specific habitats one sample (0.25 x 0.25 m plots) was taken monthly from May to July 2016.
