Organic pot-based production of basil (Ocimum basilicum L.) often has lower biomass yield than conventional cultivation. Previous investigations indicate that this growth impairment is related to high ammonium (NH4+) concentrations in the growing med

In open-field vegetable production, high quantities of soil mineral nitrogen (Nmin) and N-rich crop residues often remain in the field at harvest. After the harvest of crops in autumn, this N can lead to considerable nitrate (NO3−) losses during th

Im ökologischen Anbau von Topfbasilikum treten des Öfteren Wachstums- und Qualitätsbeeinträchtigungen auf. Diese machen sich bereits an den Jungpflanzen in Form chlorotischer und nekrotischer Keimblätter bemerkbar. Nachfolgend können Infektione

Passive Q-switched and mode-locked operation of a 2.7-μm fluorozirconate fiber laser is reported. Both mode-locking and Q-switching were attained by means of InAs epilayers used as saturable absorbers. Another technique used was the so-called flying

Passive Q-switched and mode-locked operation of a 2.7 μm fluoride fiber laser is reported. Q-switched pulses containing mode-locked pulse trains were attained by the means of InAs epilayers used as saturable absorbers. The measured mode-locked pulse

Pulsed lasers around 3μm have potential applications in the field of medicine, e.g. laser ablation of tissue, and in sensing and spectroscopy, e.g. for investigation of ultrashort processes. Fluoride fiber lasers in this range have the advantages of
