Potential use of nitrification inhibitors for mitigating N2O emission from soils
(2017-12-14)
The use of nitrification inhibitors (NI) to reduce nitrous oxide (N2O) emissions is a promising strategy to improve N fertilizer use efficiency and to help minimize emissions of the climate-relevant ...
Coupled biotic-abiotic mechanisms of nitrous oxide production in soils during nitrification involving the reactive intermediates hydroxylamine and nitrite
(2017-11-22)
Nitrous oxide (N2O) is an important greenhouse gas that can deplete the ozone layer. Microbial nitrification and denitrification have been long considered as the major contributors of soil N2O production. ...
Mainstreaming the ecosystem services approach in strategic environmental assessment of spatial planning in Chile
(2017-10-17)
Spatial planning plays a key role in policy decision-making given its influence on the future changes over the land systems and subsequently on the quality, quantity and spatial distribution of the ecosystem services (ES) ...
Drying front formation in topmost soil layers as evaporative restraint: Non-invasive monitoring by magnetic resonance and numerical simulation
(2017-04-04)
Prediction of soil moisture changes on large scales is of various interests with regard to water resources management. Within this PhD work, different Magnetic Resonance (MR) concepts/apparatus and sequences were applied ...
Genauigkeitsaspekte bei Messsystemen mit Nahbereichslaserscannern zum Pflanzenmonitoring
(2017-09-14)
Die Analyse der dreidimensionalen Struktur von Pflanzen sowie deren zeitliche Veränderung stellen einen wesentlichen Aspekt in der Pflanzenphänotypisierung dar. Zum Einsatz kommen dabei in der Regel nichtinvasive Sensoren, ...
Environmental and Health Impacts of Informal E-waste Recycling in Agbogbloshie, Accra, Ghana: Recommendations for Sustainable Management
(2016-04-14)
E-waste describes electrical and electronic equipment or parts of it that have been discarded by the owner without any intention of reuse. The annual global volumes of e-waste are rapidly increasing. In Ghana, the increasing ...
Petrogenesis of Basalt-hosted sapphires from the Siebengebirge Volcanic Field (SVF) in western Germany
(2016-04-29)
Megacysts of blue sapphires are hosted by alkaline mafic rocks from the Cenozoic Siebengebirge Volcanic Field (SVF) in western Germany. Similar occurrences of sapphires related to intra-continental alkaline mafic volcanism ...
Field observations and numerical simulations on the role of local structures and seismic source characteristics in the in uence of external earthquakes in volcanic and hydrothermal activity
(2016-02-10)
Earthquakes can trigger volcanic and hydrothermal activity at a large distance range and a wide time window. While advances in observations in the last two decades have helped to establish that there exist a causal connection ...
On High Performance Computing in Geodesy: Applications in Global Gravity Field Determination
(2014-12-08)
Autonomously working sensor platforms deliver an increasing amount of precise data sets, which are often usable in geodetic applications. Due to the volume and quality, models determined from the data can be parameterized ...
Sorption, Transformation and Transport of Sulfadiazine in a loess and a sandy Soil
(2014-12-10)
Veterinary antibiotics are unintentionally introduced into the environment and therefore found in ground and surface water, soil and sediments, air, plants etc. They enter these compartments mainly via application of manure ...
