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
Phosphorus bioavailability of biochars produced by thermo‐chemical conversionJournal of Plant Nutrition and Soil Science - Tập 177 Số 1 - Trang 84-90 - 2014
Bernd Weber, Ernst A. Stadlbauer, Elmar Schlich, Sabrina Eichenauer, Jürgen Kern, Diedrich Steffens
AbstractRecycling of P is a common strategy in efficient use of P. The aims of our investigation were to study the P extractability of biochars produced by low temperature conversion and to determine the effect of soda application on low‐temperature conversion of organic compounds and the bioavailability of P to rye grass (Lolium perenne ...... hiện toàn bộ
Pharmaceutical antibiotic compounds in soils – a reviewJournal of Plant Nutrition and Soil Science - 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
Improving potassium acquisition and utilisation by crop plantsJournal of Plant Nutrition and Soil Science - Tập 176 Số 3 - Trang 305-316 - 2013
Philip J. White
AbstractTo avoid loss of yield, crops must maintain tissue potassium (K) concentrations above 5–40 mg K (g DM)–1. The supply of K from the soil is often insufficient to meet this demand and, in many agricultural systems, K fertilisers are applied to crops. However, K fertilisers are expensive. There is interest, therefore, in reducing applicati...... hiện toàn bộ
Effects of hydrochar application on the dynamics of soluble nitrogen in soils and on plant availabilityJournal of Plant Nutrition and Soil Science - 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 dataJournal of Plant Nutrition and Soil Science - 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
