Seeds of grain legumes are currently discussed as N fertilizer in organic vegetable production. They can be produced by the farmers themselves and applied in well controlled amounts flexibly in time and space. Most research investigating the N mineralization of grain legume seeds was carried out using coarsely milled seeds. We hypothesized that seed germination alters the chemical composition leading to a higher N release compared to seed meal. In a pot experiment the C:N ratio of lupine seeds was shown to decrease noticeably within the first two weeks after sowing. After an incubation period of 1300°Cd net N mineralization was significantly higher for the lupine seedlings compared to the seed meal and close relationships between N mineralization and C:N... |
