| 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... |

| Plant based organic fertilisers were tested in plot trials on their effect as N supply for vegetable crops. Radishes (Raphanus sativus L.) and white cabbage (Brassica d-eracea var. capitata L.) were chosen as fest crops. Beside the unamended control four ({R}adish trial) and two ({C}abbage trial) fertilisers were investigated: Castor pomace (Ricinus communis L), pellets of crushed seeds of lupin (Lupinus luteus L), and faba bean (Vicia faba var. minor L.) and Phytoperls® (Zea mays L). They were applied in two N-levels {(R): 80 and 140 kg N ha-1; (C): 120 and 240 kg N ha1 with the two first mentioned fertilisers}. Castor pomace and lupin seed pellets were found to be more efficient N supplies than faba bean seed pellets and Phytoperls®; on the Iow level... |

| A survey was carried out within five European countries with regard to the practice of cereal grain legume intercropping. The mostly given combination was spring barley-spring pea beside 27 other combinations between pulses and cereals. 72 % of all examples consisted of spring varieties, the rest of winter varieties, mainly a special case of the French South West with mild winter climate. Intercrops were mainly used for feeding purposes. Best experiences were named as better yield stability, effective weed suppression, and good quality of feed. Of the negative experiences complicated mechanical weed regulation, unequal maturation and additional costs for separation were mostly named. The interviewed farmers showed predominantly positive prospects for the... |

| Curriculum development for organic agriculture was the initial point of an Erasmus group of 7 universities from 1995 till 1998. The expansion of EU member states coincided with the growing interest of further member states to become part of this informal group of university teachers. Since some years the group of meanwhile 23 countries is named ENOAT and seeks to improve the inter university exchange of students and staff members, to encourage the dissemination and implementation of organic agriculture courses, to organize annual meeting including workshops on teaching methodology, and to organize summer courses on specific topics relevant for organic agriculture. |
