Litter quality, temperature, and soil water content as drivers of decomposition and respiration in a long-term tillage trial
(2019-08)
For sugar beet cultivation in most parts of central Europe especially water erosion is a serious problem, as for in the beginning of the growing season in late spring inherent to the cultivation system large soil areas of bare soil are left poorly protected up to the time when the plants are closing in the rows (beginning of crop covering; phenological growth stages of BBCH 31 - 39) (Koch et al., 2009). Non-inversion tillage systems are an effective measure for reducing erosion risks by diminishing soil compaction ...

Die derzeitigen Probleme der EWWU – so die grundlegende Erkenntnis dieser Arbeit – sind v.a. darin begründet, dass die Währungsunion nicht durch eine adäquate Wirtschaftsunion ...

Die Physiologie des Wirts-Parasitsystems pathogener Pilze des Eschentriebsterbens
(2019)
In der vorliegenden Arbeit wurde versucht, die optimalen Wachstumsbedingungen des Pilzes H. fraxineus (Haupterreger des Eschentriebsterbens) zu ermitteln. Dafür wurden drei Wachstumsversuche (Nährmedium, pH-Wert und Temperatur) an 25 Pilzstämmen durchgeführt.
• Die Ergebnisse des Nährmediumwachstumsversuches zeigten, dass Maismehl Agar Medium (MmA) die schnellste Kultivierung des Pilzes förderte und als das optimale Nährmedium gelten kann (im Vergleich mit den anderen sechs geprüften Nährmedien).
• Der pH-Wert-Versuch ...

However, the role of German counties and local agents in Germany in general has not been analyzed from an economic perspective yet. This is the reason why my doctoral thesis investigates the role of German counties as the “forgotten” agent for the determinants and effects of local public school expenditures. This cumulative dissertation consists of three econometric papers ...
