Root-restricting layers in German agricultural soils: Extent, cause and management strategies
(2020-10-21)
Subsoil, i.e., soil below 30 cm depth, harbours great amounts of water and nutrients. However, physical and chemical barriers for vertical root elongation may restrict plants from accessing subsoil resources. Such ...
Synthese und Charakterisierung von funktionalen Lignin-basierten Polyurethan-Coatings aus unmodifiziertem und modifiziertem Kraft-Lignin
(2020-12-02)
Bedingt durch die zunehmende Rohstoffknappheit rückt die Suche nach alternativen, nachhaltigen Rohstoffen immer mehr in den Vordergrund. Im Hinblick auf effiziente chemische Verwertbarkeit bietet Lignin zahlreiche Vorteile ...
Iron isotope fractionation in arable soil and graminaceous crops
(2020-11-24)
Soils contain large quantities of Fe, however, the Fe-solubility is very low. Plants have developed two efficient strategies to secure Fe uptake from soil under Fe-deficient conditions: (i) the sequential acidification-r ...
Graph-based Sliding Window Localization and Map Refinement for Automated Vehicles
(2021-10-12)
Localization is an essential task in automated driving and advanced driver assistance systems. The precise location of a vehicle is required for extracting information from a map about the vehicle's environment. The map ...
