Methodische Probleme bei der Erstellung von Unkrautverteilungskarten mit Geoinformationssystemen (GIS)
(2005)
Die vorliegende Arbeit befaßt sich mit den methodischen Problemen, die bei der Erstellung von Unkrautverteilungskarten mit Geoinformationssystemen (GIS) auftreten können. Im Vordergrund steht dabei die Frage nach der ...
Einfluß von Vegetationsfilterstreifen auf den Austrag ausgewählter Herbizidwirkstoffe mit dem Oberflächen- und Zwischenabfluß in ackerbaulich genutzten Böden einer Mittelgebirgslandschaft
(2005)
Auf einem Ackerstandort in Velbert-Neviges mit einer Hangneigung von ca. 10 % wurde der Austrag von vier praxisüblich angewandten Herbizidwirkstoffen im Oberflächenabfluß untersucht. Zudem wurde der Einfluß von Vegetationsstreifen ...
Acceptance Analysis of New Technology for Sustainable Water Management and Sanitation: A Case Study of Operating Farm Households in the Mekong Delta, Viet Nam
(2005)
Recent development in agricultural und industrial production leads to increasing pollution of the water sources in the Mekong Delta of Vietnam. According to the "Vietnam Environment Monitor 2003 - Water", no safe drinking ...
GIS-basierte Erfassung und Prognose der räumlichen Verteilung von Pflanzenkrankheiten
(2005)
Die Erforschung der räumlichen Verteilung von Pflanzenkrankheiten wurde bisher in der Phytomedizin vernachlässigt, da keine adäquaten Mittel zur Verfügung standen, um die auftretenden Phänomene analysieren und darstellen ...
Non-invasive monitoring of water and solute fluxes in a cropped soil
(2010-12-15)
Although the influence of root water uptake on solute transport is commonly recognized as important, it has barely been studied throughout the literature. However, plants take up a big amount of the infiltrating water and ...
Interpretation of L-band brightness temperatures of differently tilled bare soil plots
(2015-12-03)
The structure of the surface soil layer is strongly influenced by soil tillage practices with important consequences for the soil hydraulic properties and soil moisture dynamics in the top soil layer. In this study, an ...
Efficient Semantic Scene Understanding for Mobile Robots
(2021-12-16)
Over the last few years, robots have been slowly making their way into our everyday lives. From robotic vacuum cleaners picking up after us already working in our homes, to the fleets of robo-taxis and self-driving vehicles ...
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. ...
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 ...
Agroforestry as a post-mining land-use approach for waste deposits in alluvial gold mining areas of Colombia
(2018-05-30)
Alluvial gold mining generates a vast amount of extractive waste that completely covers the natural soil, destroys riparian ecosystems, and negatively impacts river beds and valleys. Since 2002, a gold mining company has ...
