| Knowledge about organic agriculture is constantly changing and growing. Research related to organic agriculture at EU level nowadays plays an important role. Organic agriculture, being an integrated, holistic and multi-target approach, needs researchers who are trained to investigate poly-factorial and multi-level problems. For students and junior scientists, international seminars and exchange programs are necessary instruments to gain “state of the art” knowledge and skills from senior scientists in the field of organic agriculture. The QLIF training programme under WP7.4 provides training in the different aspects of ecological farming systems, but also offers an opportunity to discuss relevant and adequate research strategies and results. Within the EU... |

| The nitrogen of organic fertilizers does not fully mineralize within a season, and hence will partly become available in later years. This effect is taken into account for the first year but generally not in later fertilizer applications. If it would be taken into account, fertilizer use could be more efficient. This study is an analysis of a 13-year field trial where crop yield was measured in 13 fertilizer treatments which differ in total N applied and decomposition rate. This is complemented with a model study in which mineralization and soil nitrogen content were calculated. We intended to show step by step that the use of fertilizers with a low decomposition rate, relative to fertilizers with a high decomposition rate, lead in the course of years to... |
