| In diesem Projekt sollten verschiedene vegetabile Düngemittel hinsichtlich ihrer Stickstoff-Düngewirkung im ökologischen Gemüseanbau als Alternative zu organischen Düngemitteln tierischer Herkunft untersucht werden. Folgende Düngemittel wurden untersucht: (1) In Inkubationsversuchen bei 5 und 15°C Ackerbohnenschrot (Vicia faba L., Körnerschrot), Körnerschrote der Gelben und der Weißen Lupine (Lupinus albus L. und Lupinus luteus L.), Bio-Vegetal®, Phytoperls®, Rizinusschrot (Ricinus communis L., Körnerschrot) als gebräuchlicher vegetabiler Importdünger und Hornmehl als Referenzdünger tierischer Herkunft; (2) in Gefäßversuchen Ackerbohnenschrot, Körnerschrot der Gelben Lupine, Phytoperls®, Rizinusschrot und Hornmehl; (3) in Feldversuchen... |

| During the last years, an increasing number of stockless farms in Europe converted to organic farming practice without re-establishing a livestock. Due to the lack of animal manure as a nutrient input, the relocation and the external input of nutrients is limited in those organic cropping systems. The introduction of a one-year green manure fallow in a 4-year crop rotation, including clover-grass mixtures as a green manure crop is the classical strategy to solve at least some of the problems related to the missing livestock. The development of new crop rotations, including an extended use of catch crops and annual green manure (legumes) may be another possibility avoiding the economical loss during the fallow year. Modelling of the C and N turnover in... |
