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 ...
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 ...
Conceptualizing the concept of disaster resilience: a hybrid approach in the context of earthquake hazard: case study of Tehran City, Iran
(2017-05-19)
From the natural perspective, disaster resilience is defined as the ability of a system or community to resist, mitigate, respond, and recover from the effects of hazards in efficient and timely manner. How urban communities ...
Phosphorus forms in fertilized arable soil profiles and related 33P uptake
(2019-09-13)
Arable soils usually store several thousand kg phosphorus (P) per ha, thus far exceeding the recommended P fertilizer dose to sustain crop yields. However, the soil profile is frequently not considered in fertilizer ...
