| To describe spatial heterogeneity of crop properties, non-destructive methods can be helpful in capturing whole field data sets. This paper shows examples of different sensor methods that have been evaluated to measure biomass and legume content in legume-grass mixtures. Biomass has been estimated using vegetation indices (NDVI, SR, EVI and REIP) calculated from spectral reflectance measurements in greenhouse experiments. The index REIP has been used to identify species composition as well. Furthermore, biomass values can be derived from ultra sonic measurements of sward heights. To quantify legume contents in short term leys, which is important for forage quality and nitrogen flows, image analysis tools have been used in different experi-ments with good... |

| Det grovfoder som idag används till nöt består framförallt av olika arter av gräs och klöver från fleråriga vallar. Baljväxterna i vallen fixerar luftkväve och bidrar därigenom med ett nödvändigt näringstillskott också till efterföljande grödor. För en ekologisk lantbrukare är det mycket fördelaktigt, både ur närings- och fodersynpunkt, att även ettåriga kvävefixerande grödor kan ingå i växtföljden. Genom samodling av spannmål och trindsäd (t.ex. ärter) för helsädesensilering kan hela plantan skördas vid ett och samma tillfälle samtidigt som ett energi- och proteinrikt foder fås. Trots att odling av spannmålsgrödor för helsädesensilering varit relativt vanlig i t.ex. Danmark har det varit ovanligt inom svenskt, konventionellt... |

| The objective of this study was to compare the agronomic performance of different forage legume species submitted to different management systems, i.e. grazing, silage-cut and simulated grazing to find alternatives for white clover. The experiment was established in 2003 and 2004 as binary swards with perennial ryegrass (Lolium perenne L.) as the companion grass with three replicates in two different sites on the experimental station “Lindhof” of the University of Kiel. Legume species were arranged within each management system as completely randomised blocks. Results of agro-nomic performance of the first production years in 2004 and 2005 (DM-yield, botanical composition, N-yield, N-content) are presented for white clover swards (Trifolium repens L.), red... |

| Introduction Agricultural cropping systems generally have a limited use of water and nutrients from the soil below 1m depth. However, several plant species have much deeper root systems, and if included in cropping systems, these would allow for exploitation of otherwise unused resources from deep soil layers. In a unique facility consisting of 12, 4m high ‘root towers’ we examined the root development and root activity in different soil layers of different biannual/perennial plant species. Methods Four plant species lucerne (Medicago sativa), rosinweed (Silphium integrifolium), intermediate wheatgrass (Thinopyrum intermedium), and dyers voad (Isatis tinctoria) were grown in soil in large rhizotrons (root towers) (4m×1.2m×0.6 m). Root growth was... |

| One way of reducing the emissions of fossil fuel-derived carbon dioxide (CO2) is to replace fossil fuels with biofuels produced from agricultural biomasses or residuals. However, cultivation of soils results in emission of other greenhouse gasses (GHGs), especially nitrous oxide (N2O). Previous studies showed that field emissions of N2O may contribute significantly to total GHG emissions during biofuel production. Furthermore, N2O may counterbalance a considerable part of the global warming reduction, which is achieved by fossil fuel displacement. In the present study, we related measured field emissions of N2O to the reduction in fossil fuel-derived CO2, which was obtained when agricultural biomasses were used for biofuel production. The analysis included... |

| Em regiões de clima tropical, com altas taxas de decomposição do material orgânico, uma alternativa para suprir o aporte anual de palha exigido para proporcionar a sustentabilidade do sistema plantio direto é a consorciação de forrageiras com culturas produtoras de grãos. Com o objetivo de identificar, no sistema de integração agricultura-pecuária, a melhor modalidade de consorciação de três espécies de braquiária (Brachiaria brizantha B. decumbens, e B. ruzizienses) com milho outonal (linha, entrelinha e entrelinha na época de adubação de cobertura do milho), foi conduzido o presente trabalho. Foi utilizado o delineamento em blocos ao acaso, no esquema fatorial (3x3), com quatro repetições. Foram avaliadas: massa seca de palha do milho, massa seca da... |

| In view of climate change predictions and the general desirability of increasing the amount of home grown protein, a case exists for the investigation of lupins and lupin/cereal bicrop combinations as wholecrop forage on organic farms. A replicated randomised block trial is described which took place at the Royal Agricultural College, Cirencester, in 2005. This involved spring sown blue, white and yellow lupins, millet, wheat and triticale and lupin/cereal bi-crops. Data for dry matter yields for wholecrop silage, crude protein, MAD fi bre content and estimated ME, are presented for a single harvest. It is concluded that white lupins and white lupin bi-crops with spring wheat or triticale offer the best prospects for a viable wholecrop forage crop in an... |

| Soil nitrogen fertility management is a major concern in organic farming. Nitrogen fixation by legumes is a potential solution especially in multi-annual crop rotation program. This study aims at assessing the effect of fifteen legume cultivars on wheat as third subsequent crop and at identifying the most efficient and suitable cultivars for a long-term rotation program.T. subterraneum cv. York and T. glanduliferum cv. Prima induced the best effects on wheat, particularly on total biomass, number of grains, dry matter production and increased yield by 670% and 567% respectively compared to the control. They showed also, together with Trifolium subterraneum cv. Dalkeith and Trifolium incarnatum cv. Caprera, to be the most efficient over the whole rotation... |

| Im Rahmen des Forschungsschwerpunktes „Ökologischer Landbau und extensive Landnutzungssysteme“ wurden auf dem Versuchsgut für Ökologischen Landbau der Universität Kiel (Lindhof) in den Jahren 1999-2003 Untersuchungen zur Optimierung des N-Transfers vom Kleegras zur Folgefrucht Getreide durchgeführt. Als Versuchsfaktoren wurde die Kleegras-Bewirtschaftung (3x Schnittgutabfuhr, 2x Schnittgutabfuhr + 1x Mulchen, 3x Mulchen), die Umbruchart (Pflug, Fräse + Pflug), der Umbruchtermin (Herbstumbruch/ Winterweizen, Frühjahrsumbruch/ Sommerweizen bzw. Hafer) und eine organische Düngung zu EC 45 (0, 75 kg N/ha) geprüft. Die Kleegras-Bewirtschaftung beeinflusste nicht den Kornertrag von Winterweizen (Ø 48,4 dt/ha), Sommerweizen (Ø 46,6 dt/ha) und Hafer (Ø 58,5... |

| Rotklee bzw. Luzerne als Reinsaat bzw. im Gemenge mit Gräsern stellen in zahlreichen ökologisch wirtschaftenden Betrieben die Basis der Winterfutterversorgung dar. Wenige vergleichende Untersuchungen liegen zum Leistungspotential von Rotklee und Luzerne unter mitteleuropäischen Klimaverhältnissen vor. Vor diesem Hintergrund wurde im Rahmen eines Feldversuches der Einfluß der Faktoren Leguminosenart (Rotklee, Luzerne), Leguminosen/Gras-Saatmischungsverhältnis (Leguminosereinsaat, Grasreinsaat, leguminosereiche bzw. leguminosenarme Saatmischung) sowie Begleitgrasart (Dt. Weidelgras, W.Weidelgras) auf die Parameter Ertrag, Leguminosenanteil sowie die Futterqualitätsparameter RP-Gehalt, Nettoenergiekonzentration, ADF-, und ADL-Gehalt untersucht. Im Mittel... |

| An zwei Standorten in Mecklenburg Vorpommern sind über einen Zeitraum von 2010 bis 2015 alternative Leguminosen-Gras-Gemenge unter ökologischen Bedingungen hinsichtlich Ertrag und ausgewählter Futterwerteigenschaften geprüft worden. Mit höherem Leguminosenanteil stieg an beiden Standorten auch der Trockenmasseertrag. Auch auf dem sorptionsschwachen Standort Plöwen erwiesen sich die Gemenge bei etwas niedrigerem Niveau als vergleichsweise ertragsstabil. Die Ertragsunterschiede zwischen den Gemengen ließen sich statistisch nicht absichern. Die Futterqualität entsprach bei qualitätsorientierter Nutzung den hohen Anforderungen der ökologischen Milchproduktion. Sowohl in frischem als auch in getrocknetem Zustand wurden im Rohprotein sehr hohe Anteile an... |

| In comparison to harvesting, grazing is less cost intensive. For economical reasons an extended duration of grazing period is recommended. Grazing during winter can cause pasture damages, which is of minor relevance for older grass clover grown on arable land, which will be ploughed in the following spring. Against this background yield and forage quality of 3 different legume species, i.e. white clover, red clover and alfalfa, grown in binary mixtures with two grass species, perennial ryegrass and tall fescue, respectively, were examined before grazing the third growth in autumn or winter. Nitrate leaching losses during winter and yield of the following spring wheat were recorded. Yield and forage quality of the total sward was not significantly... |
