Pharmaceutical antibiotic compounds in soils – a review Tập 166 Số 2 - Trang 145-167 - 2003
Sören Thiele‐Bruhn
AbstractAntibiotics are highly effective, bioactive substances. As a result of their consumption, excretion, and persistence, they are disseminated mostly via excrements and enter the soils and other environmental compartments. Resulting residual concentrations in soils range from a few μg upto g kg–1 and correspond to those found for pesticide...... hiện toàn bộ
Stabilization mechanisms of organic matter in four temperate soils: Development and application of a conceptual model Tập 171 Số 1 - Trang 111-124 - 2008
Margit von Lützow, Ingrid Kögel‐Knabner, Bernard Ludwig, Egbert Matzner, Heinz Flessa, Paula Fernandes, Georg Guggenberger, Bernd Marschner, Karsten Kalbitz
AbstractBased on recent findings in the literature, we developed a process‐oriented conceptual model that integrates all three process groups of organic matter (OM) stabilization in soils namely (1) selective preservation of recalcitrant compounds, (2) spatial inaccessibility to decomposer organisms, and (3) interactions of OM with minerals and metal ions. The mode...... hiện toàn bộ
Short‐term and residual availability of nitrogen after long‐term application of organic fertilizers on arable land Tập 168 Số 4 - Trang 439-446 - 2005
R. Gutser, Th. Ebertseder, Andreas Weber, M. Schraml, Urs Schmidhalter
AbstractKnowledge on short‐term and long‐term availability of nitrogen (N) after application of organic fertilizers (e.g., farmyard manure, slurry, sewage sludge, composts) provides an important basis to optimize fertilizer use with benefits for the farmer and the environment. Nitrogen from many organic fertilizers often shows little effe...... hiện toàn bộ
Innovative methods in soil phosphorus research: A review Tập 178 Số 1 - Trang 43-88 - 2015
Jens Kruse, Marion Abraham, Wulf Amelung, Christel Baum, Roland Bol, Oliver Kühn, H. Lewandowski, Jörg Niederberger, Yvonne Oelmann, Christopher P. Rüger, Jakob Santner, Meike Siebers, Nina Siebers, Marie Spohn, Johan Vestergren, Angela Vogts, Peter Leinweber
AbstractPhosphorus (P) is an indispensable element for all life on Earth and, during the past decade, concerns about the future of its global supply have stimulated much research on soil P and method development. This review provides an overview of advanced state‐of‐the‐art methods currently used in soil P research. These involve bulk and spatially resolved spectro...... hiện toàn bộ
The effect of nitrification inhibitors on the nitrous oxide (N2O) release from agricultural soils—a review Tập 178 Số 2 - Trang 171-188 - 2015
Reiner Ruser, Rudolf Schulz
AbstractThe use of nitrification inhibitors (NI) is a technique which is able to improve N fertilizer use efficiency, to reduce nitrate leaching and to decrease the emission of the climate‐relevant gas N2O simultaneously, particularly in moderately fertilized agricultural systems adapted to plant N demand. The ammonia monooxygenase (AMO) is the...... hiện toàn bộ
Methods of collection of plant root exudates in relation to plant metabolism and purpose: A review Tập 176 Số 2 - Trang 175-199 - 2013
Valerie Vranová, Klement Rejšek, Keith R. Skene, Dalibor Janouš, Pavel Formánek
AbstractThe aim of this work is to review the current knowledge on the effects of plant metabolism (C3, C4, and CAM) on root exudation and on the methods of exudate collection as well as the use of such exudates for analyses, testing of microbial response, degradation of pollutants, enzymatic activities, and occurrence of a...... hiện toàn bộ
Effects of hydrochar application on the dynamics of soluble nitrogen in soils and on plant availability Tập 177 Số 1 - Trang 48-58 - 2014
Inge Bargmann, Matthias C. Rillig, Andrea Kruse, Jörg‐Michael Greef, Martin Kücke
AbstractBefore hydrochars can be applied as soil amendments in agriculture, information about how hydrochar application affects soil nutrient cycles and plant growth are necessary. In this study, incubation experiments were performed to investigate hydrochar effects on N concentrations (NO$ _3^- $ hiện toàn bộ
Nitrous oxide emissions from agricultural land use in Germany— a synthesis of available annual field data Tập 169 Số 3 - Trang 341-351 - 2006
Hermann F. Jungkunst, Adrian Leip, Henry Neufeldt, Georg Bareth
AbstractThe nations that have ratified the Kyoto Protocol must set up an appropriate national inventory on N2O emissions from agricultural land use, in order to report properly on the achievements made in reducing greenhouse‐gas emissions. The search for the appropriate method is a controversial topic as it is subject to high uncertainty in par...... hiện toàn bộ
