Properties of peat and other organic soils from temperate European climates: Part I – Physical and chemical characteristics

Ullrich Dettmann, Bärbel Tiemeyer, Sebastian Heller, Merten Minke et autres

• A large and consistent dataset on peat and other organic soils was characterised. • Field-assessed and laboratory-measured properties revealed clear dependencies. • Fen peat exhibited lower soil organic carbon contents than bog peat. • Bulk densities of organic soils varied by …

Dataset on the physical and chemical properties of European peat and other organic soils

Ullrich Dettmann, Bärbel Tiemeyer, Sebastian Heller, Merten Minke et autres

This dataset contains information on the properties of peat, gyttja and other organic soils. It includes results of laboratory measurements of bulk density, porosity (equivalent to saturated water content), soil organic carbon content, nitrogen content, soil organic carbon density, and nitrogen density. …

Effect of high frequency subsurface drip fertigation on plant growth and agronomic nitrogen use efficiency of red cabbage

Ana Claudia Callau Poduje, Martin Mungai Mburu, Caspar-Friedrich Weßler, Nasser Amer et autres

High emissions of nitrogen to the environment are one of the major drawbacks of modern agriculture. Subsurface drip fertigation (SDF) is a technology to apply fertilizer in small amounts continuously and directly into the root zone with the potential of mitigating deep …

Updated map of organic soils in Germany: [Dataset]

Mareille Wittnebel, Stefan Frank, Bärbel Tiemeyer

Die aktualisierte Kulisse der organischen Böden in Deutschland (2023) stellt die Moor- und weiteren organischen Böden in Deutschland dar. Sie enthält harmonisierte Informationen u.a. zu verschiedenen Kategorien von organischen Böden, zur anthropogenen Überprägung durch Tiefpflügen oder der Überdeckung mit Mineralboden, zur Mächtigkeit …

How to take volume-based peat samples down to mineral soil?

Ullrich Dettmann, Stefan Frank, Mareille Wittnebel, Arndt Piayda et autres

Determination of soil organic carbon stocks in peat soils is of major importance for prioritization and evaluation of mitigation measures. This requires the accurate assessment of bulk density, which is commonly undertaken by measuring the oven-dry weight of a volume-based sample. Sample …

Peat and other organic soils under agricultural use in Germany: Properties and challenges for classification

Mareille Wittnebel, Bärbel Tiemeyer, Ullrich Dettmann

Under natural conditions, peatlands store large amounts of soil organic carbon (SOC). However, they are under threat due to drainage which leads to mineralisation of soil organic matter to carbon dioxide (CO2). This situation is especially severe in Germany, where more than …

Stocks of organic carbon in German agricultural soils—Key results of the first comprehensive inventory

Christopher Poeplau, Anna Jacobs, Axel Don, Cora Vos et autres

Abstract Background: There is considerable uncertainty about the actual size of the global soil organic carbon (SOC) pool and its spatial distribution due to insufficient and heterogeneous data coverage. Aims: We aimed to assess the size of the German agricultural SOC stock …

Landwirtschaftlich genutzte Böden in Deutschland: Ergebnisse der Bodenzustandserhebung

Anna Jacobs, Heinz Flessa, Axel Don, Arne Heidkamp et autres

Die Bundesrepublik Deutschland hat sich als Unterzeichnerstaat mehrerer internationaler Vereinbarungen zum Klimaschutz verpflichtet, anthropogene Quellen und Senken von Treibhausgasen jährlich auf nationaler Skalenebene zu berichten. Dazu zählen auch CO2-Emissionen aus Veränderungen des Vorrates an organischem Kohlenstoff (Corg) im Boden - denn ein …
