Root length and root diameter classes after 33 days. In columns 3-12 the measured values are given in centimetres (cm), not in millimetres (mm) as indicated in the file.
Primary and secondary metabolites detected in roots of Rosa corymbifera 'Laxa' grown in different treatments of rose replant disease soil, Yim et al. 2020_rose replant disease Research domain: Other Research question: are there differences between the primary and secondary metabolites in roots of R. 'Laxa' grown in untreated and treated rose replant disease soil?
In recent years, the interest in subsoil has increased, since it can hold immense reservoirs of nutrients, organic matter and water. The subsoil can therefore provide important ecosystem services for the agricultural production system and beyond. This paper assesses the sustainability of two subsoil management measures with regard to the delivery of soil-related ecosystem services: a) the cultivation of deep-rooted pre-crops (biological approach) and b) stripwise mechanical subsoil loosening in combination with the incorporation of...
This handbook is designed to support researchers in conducting state of the art assessments for evaluating impacts of agricultural soil management. Furthermore, it is addressed to a wider audience to aid understanding and interpretation of published impact assessments results. The handbook has been produced in response to a growing awareness of the fundamental role of soils and of the importance of sustainable soil management for coping with societal challenges such as food security, climate change...
Goal of modern research data management is to provide user-friendly infrastructures to upload, manage and provide research data in findable, accessible, interoperable and reusable formats for continued use (= ”FAIR data principles”). To meet these requirements, the application of accepted and widely used standards, regulations, conventions and guidelines for the different stages of research data life is necessary. With regard to agricultural science, such standards concern a wide field, e.g. the classification and description of...
CO2-Zertifikate für die Festlegung atmosphärischen Kohlenstoffs in Böden: Methoden, Maßnahmen und GrenzenMartin Wiesmeier, Stefanie Mayer, Carsten Paul, Katharina Helming, Axel Don, Uwe Franko, Markus Franko & Ingrid Kögel-Knabner
Agrarböden besitzen durch den Aufbau von organsicher Bodensubstanz (Humus), die zu etwa 58% aus Kohlenstoff (Corg) besteht, ein großes Potential zur Kohlenstoffbindung. Positive Anstrengungen im Humusmanagement könnten daher einen wesentlichen Beitrag für den Klimaschutz leisten. Für Landwirtinnen und Landwirte stellen so genannte CO2-Zertifikate für den Aufbau von Corg („Humuszertifikate“) einen zusätzlichen Anreiz dar, humusfördernde Bewirtschaftungsmaßnahmen umzusetzen. Diese CO2-Zertifikate werden von privatwirtschaftlichen Initiativen und Unternehmen im Bereich des freiwilligen CO2-Markts vergeben. Insbesondere im Bereich der Landwirtschaft...
An implementation of SRS in R is available for download: https://b-web.bonares.de/smartEditor/rest/upload/ID_7049_2020_05_13_SRS_function_v1_0_R.zip Scaling with ranked subsampling (SRS) is an algorithm for the normalization of species count data in ecology. So far, SRS has successfully been applied to microbial community data. SRS consists of two steps. In the first step, the counts for all OTUs (operational taxonomic untis) are divided by a scaling factor chosen in such a way that the sum of the scaled counts (Cscaled...
General description of the Long-term Field Experiment "V140": The long-term field experiment "V140" was established in 1963 at the experimental site of the present Leibniz Centre for Agricultural Landscape Research about 50 km east of Berlin in the district Märkisch-Oderland. The area is characterized by dry periods, particularly during early summer. Weather data for the running period of V140 are available at the DWD (station number 03376) ftp://ftp-cdc.dwd.de/pub/CDC/observations_germany/climate/daily/kl/historical/tageswerte_KL_03376_19490101_20171231_hist.zip. The V140 represents one of the few...
This data set contains leaf litter, woody biomass, grain, shredded corn, straw and grass production on the sites of SIGNAL (Sustainable Intensification of Agriculture through Agroforestry) at Dornburg (Thuringia), Forst (Brandenburg), Wendhausen and Mariensee (both Lower Saxony). Research domain: Ecology of Agricultural Landscapes Research question: Does alley-cropping agroforestry pose a more sustainable alternative to conventional monocultures?
Barley (Hordeum vulgare) and bristle oat (Avena strigosa) were harvested at the agroforestry site in Forst and the reference site on July 25th, 2019, and July, 30th 2020, respectively. After plots were harvested using a plot combine harvester subsamples were oven dried for 24 hrs at 105°C to determine water content and dry weights of the samples. The table contains the fresh weights of the harvested barley and bristle oat corn and straw biomass, the...
