| Legumes and herbs are able to contribute to productivity and biodiversity in forage production. Besides they are known for beneficial properties for nutritive value and animal health. In the present study the potential yield and forage quality of eight legumes, four herbs and perennial ryegrass were tested under growing conditions in northern Germany. Due to their ability to bind protein and affect ruminal fermentation in a favourable manner, concentration of condensed tannins (CT) and total phenols (TP) were measured. Regarding some forage quality parameters, herbs and alternative legumes were equal or even exceed standard species. In general, herbs were lower in dry matter yield and crude protein, but higher in energy content and TP. Highest TP were... |

| In einem konzeptionellen Projektansatz, der sowohl Felderhebungen, Feldversuche, Gefäßversuche und Laboranalysen umfasste, wurde der Frage der Bedeutung der Bodenphosphor-Trophie für die Präsenz, die Entwicklung und die Leistungsfähigkeit von Grünlandleguminosen im Ökologischen Landbau nachgegangen. Ziel der Untersuchungen war es, die Bivalenz des Phosphors, der einerseits die Leguminosen und damit den N-Ertrag fördern kann und andererseits die Phytodiversität zu reduzieren vermag, näher zu ergründen. Es zeigte sich, dass die Präsenz von Grünlandleguminosen auf heterogenem Dauergrünland weder vom Gehalt an pflanzenverfügbarem P noch den einzelnen P-Fraktionen hinreichend erklärt werden konnte. Demnach spielen erratische bzw. weitere nicht kontrollierte... |

| Objetivou-se avaliar o valor nutritivo do capim-elefante, quanto aos teores de PB e FDN e a digestibilidade in vitro da MS (DIVMS), submetido a algumas práticas agroecológicas. Foram usados dois piquetes (0,15 ha cada), onde foi estabelecido o capim-elefante, em 2001, com espaçamento entrelinhas de três metros. Nas entrelinhas, estabeleceram-se aveia (Avena strigosa Schreb.) e azevém (Lolium multiflorum Lam.) no período hibernal e, no estival, permitiu-se o desenvolvimento de espécies de crescimento espontâneo. A adubação foi feita com fertilizantes orgânicos (150 kg de N /ha). No período experimental (24/04/2004 a 05/05/2005), foram conduzidos sete pastejos. Os animais experimentais foram vacas da raça Holandesa que receberam, como complementação... |

| The contribution of biologically fixed dinitrogen (N2) to the nitrous oxide (N2O) production in grasslands is unknown. To assess the contribution of recently fixed N2 as a source of N2O and the transfer of fixed N from clover to companion grass, mixtures of white clover and perennial ryegrass were incubated for 14 days in a growth cabinet with a 15N2-enriched atmosphere (0.4 atom% excess). Immediately after labelling, half of the grass-clover pots were sampled for N2 fixation determination, whereas the remaining half were examined for emission of 15N labelled N2O for another eight days using a static chamber method. Biological N2 fixation measured in grass-clover shoots and roots as well as in soil constituted 342, 38 and 67 mg N m-2 d-1 at 16, 26 and 36... |

| Red clover-grass leys were fertilized with cow manure or with chemical fertilizers. The yields were lower with organic fertilizers, but nevertheless the GHG emissions were lower per tonne of biomass in organic than in conventional conditions, even when the extra need for cultivation area to gain equal amounts of yield was considered.

| Bælgplanter, herunder de forskellige kløverarter, kan ved knoldbakteriers hjælp (symbiose) optage luftens kvælstof (N2), og derved udnytte denne uudtømmelige kvælstofkilde. Processen er simpelt-hen forudsætningen for at kunne drive økologisk jordbrug, og det har derfor stor interesse at kende størrelsen af N-fikseringen og have kendskab til hvilke faktorer der har betydning for derved om muligt at kunne optimere produktiviteten og reducere eventuelle miljømæssige effekter af et givet dyrkningssystem. |

| In der ökologischen Grünlandbewirtschaftung werden artenreiche Bestände mit Standort angepassten und möglichst wertvollen Futterarten angestrebt. Dennoch sind in der Praxis oftmals stark Weidelgras betonte Bestände anzutreffen. Im Vergleich zur Neuansaat sind Nachsaaten deutlich kostengünstiger. Daher wurden im Sommer 2007 auf 8 ökologisch bewirtschafteten Betrieben Nord-Westdeutschlands Nachsaatversuche mit unterschiedlicher Technik (Schlitzsaat und Bandfrässaat) und ausgewählten Arten angelegt. Hierbei würden 5 Gramineen (Lolium perenne, Phleum pratense, Festuca rubra, Dactylis glomerata) und auf drei Standorten in Niedersachsen zusätzlich Festulolium, eine Neuzüchtung aus Festuca- und Lolium-Gattungen sowie eine Futterleguminose (Lotus corniculatus)... |

| Nowadays, the organic farming sector is rapidly increasing in order to meet the increasing demand for organic products. However, the scarce availability of organic feed for monogastric animals together with the lack of organic fertilizers are challenging the development of this sector. In this context, a Danish project called Organofinery is focusing on developing a green biorefinery platform for the production of organic protein-rich feed for monogastric animals, of biogas and of organic fertilizer. In the Organofinery concept, the freshly harvested green biomass is separated by a screw press into a green juice and a press cake. Soluble sugars contained in the green juice are fermented by specific lactic acid bacteria, leading to a drop of the pH and... |

| Amounts of rapidly rumen degradable protein in forage plants breed to a lower N-Use-Efficiency (NUE). Secondary plant metabolites, like tannins are able to protect forage protein against inefficient ruminal degradation. Feeding forage plants containing moderate concentrations of tannins may increase the sustainability in organic dairy production. This study was carried out to investigate the potential of several home-grown plants to bind forage protein and thus decrease ruminal N losses. A choice of six weeds and nine legumes were analyzed in terms of the composition of crude protein according to the Cornell Net Carbohydrate and Protein System, levels of condensed tannins (CT), total phenols (TP) and the ability to precipitate the model protein Bovines... |

| The aim of this work was to identify the impact of farming practices on permanent grassland vegetation during the conversion from conventional to organic farming. We considered functional and species diversities in order to compare the different grassland categories based on the farming practices used over a period of six years - five years before conversion and one year after. We identified three categories of grasslands: those generally cut twice a year, those intensely grazed, and those that were used under diversified practices. We showed that grasslands characterised by cutting and low fertilization level have the highest species richness compared to the other two categories (23.2, 16.9 and 17 species, respectively), and the lowest pastoral index... |

| Il s’agit d’évaluer l’impact environnemental (sur air et eau) des systèmes d’élevage de ruminants en agriculture biologique ( NH3, N2O, NO3 , CH4, CO2,). Le projet s’articule autour de deux approches, l’une très précise dans deux stations expérimentales biologiques, l’autre en fermes d’éleveurs biologiques ou de lycée agricole au système proche des systèmes d’élevage étudiés en station et que nous appelleront « fermes satellites ». Les calculs en stations expérimentales seront réalisés à partir de données journalières concernant l’alimentation des animaux, les productions, l’utilisation des parcelles par les animaux et toutes les pratiques de fertilisation et de récolte. Tous les flux internes et externes de matières seront l’objet de pesées et d’analyses.... |

| Køer, der leverer økologisk mælk, skal i praksis fodres med 100% økologisk foder. Derfor spiller afgræsning en aktuel og vigtig rolle for fodringen. På Rugballegård ved Danmarks JordbrugsForskning undersøgte vi, om det er muligt at maksimere optagelsen under afgræsning ved at bruge et leder-følge system. Ved udbinding havde vi 12 folde, som i løbet af sæsonen blev udvidet til 18 folde efterhånden som væksten af kløvergræsset blev mindre. Malkekøerne græssede to døgn både dag og nat i hver fold, inden de blev flyttet til næste fold, dvs. systemet er et rationsgræsningsprincip. Det nye er, at kvierne sammen med goldkøerne fulgte efter. Når køerne havde græsset en fold i to døgn, græssede kvierne og goldkøerne folden de næste to døgn. Køerne, der er... |

| Opløst organisk stof danner grundlaget for mange af de biogeokemiske processer der foregår i jorden. Der er foretaget talrige undersøgelser af dannelse og tab af organisk stof fra skovjorde, hvorimod kun få er gennemført i landbrugsjord. Det vides at græsmarker øger jordens pulje af organisk stof, men kendskabet til det organiske stofs skæbne efter ompløjning af græsmarker er mangelfuldt. Formålet med denne undersøgelse var at bestemme størrelsesordner for udvaskning af opløst organisk kulstof (DOC) og den samlede mængde mobilt organisk kulstof (MOC) i dyrkningssystemer med kløvergræs, med særlig fokus på perioden efter ompløjning af græsmarken. Undersøgelserne er gennemført dels i Foulum i et markforsøg anlagt med henblik på at måle kvælstofudvaskning og... |

| Because of lower nitrogen (N) input it is assumed that organically cultivated legumes fix more N2 than legumes grown under conventional cropping. Using the natural 15N abundance method, we assessed symbiotic N2 fixation by white and red clover. The clover was growing in a grass-clover meadow installed as part of the crop rotation of a long term (30 years) field experiment. Dry matter yields were similar for organic and conventional meadows on plots fertilized at levels typical for the respective system, but organic meadows tended to higher clover yields. The proportion of N derived from atmosphere (Ndfa) in both clover species was on average 84%. It was not significantly affected by the cropping system. Because of more legumes, amounts of fixed N2... |

| Rapporten har til formål at belyse markedspotentialet for økologisk græsprotein til fodring af økologisk fjerkræ – fortrinsvis høner. Danmark er det centrale marked for rapporten, men der indgår også betragtninger om Sverige, Tyskland og Frankrig for at perspektivere analysen. Økologisk græsprotein er ikke et produkt, der reelt eksisterer i markedet i skrivende stund. Derfor er beregningerne baseret på en række antagelser, som det er anført i rapporten. Markedsrapporten skal ses i sammenhæng med øvrige leverancer fra projektpartnerne i OrganoFinery. Rapporten bygger bl.a. på resultater af forsøg med fodring af fjerkræ udført ved Foulum, udviklingsarbejde for at forbedre fermenteringsteknologien, erfaringer indhentet ved brug af pilotanlæg i Foulum til... |
