Última Competitive forbs in high-producing temporary grasslands with perennial ryegrass and red clover can increase plant diversity and herbage yield Organic Eprints Nawa Raj, Dhamala; Karen, Søegaard; Jørgen , Eriksen. In highly productive temporary grasslands in Europe, plant diversity is usually low. Some non-leguminous species have shown a high competitive ability in temporary grasslands and can increase plant diversity without compromising yields. In an experiment, the competitiveness and productivity of three forb species: chicory (Cichorium intybus), ribwort plantain (Plantago lanceolata) and caraway (Carum carvi), grown in different proportions in mixtures including traditional sown grassland species, perennial ryegrass and red clover, were examined with slurry application as an additional factor. Dry matter (DM) yield and botanical composition were measured during one complete growing season. Annual DM yields were mostly similar when forbs were included in the...

This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR). This paper outlines some of the factors influencing the level of forage production on organic lowland farms. Optimal forage production is achieved by maintaining soil fertility, providing a balance between N-fixing and N-demanding crops and producing sufficient quantities of quality feed to meet the requirements of the organic livestock enterprise. A key objective for organic systems is to increase the efficiency of forage production by improving the nutrient input/output balance of the wholefarm system. Improving forage quality reduces the requirement for external feed sources, leading to increased self-sufficiency in the wholefarm system....

Ano: 2023 Micro-mineral profile in different grassland species Organic Eprints Søegaard, K.; Sehested, J.; Jensen, S.K.. The aim was to investigate the micro-mineral profile of herbage as affected by grassland species, cutting time and seasonality and in relation to dairy cow requirements. The different grassland species were grown and harvested in mixtures with one grass and one legume for two growing seasons. The species turned out to have very individual mineral profiles, not influenced by year. Among the legumes red clover (Trifolium pratense) had high concentrations of Co, Cu and Zn, white clover (Trifolium repens) of Mn and Fe, lucerne (Medicago sativa) of Se and lotus (Lotus corniculatus) of Co, Mn, Zn and Fe. Among the grasses perennial ryegrass (Lolium perenne) generally had the highest concentrations of all the micro-minerals. Hybrid ryegrass (Lolium hybridum) had...

In 2012 about 25 % of permanent Austrian grasslands were managed organically. At the same time the farms enlarged their average field areas especially in Alpine regions. In order to investigate intensification limits of montane meadows, an on-farm field experiment at the Upper Styrian Pöls valley was established in 2008. The triannual case study consisted of a balanced incomplete block design with 30 sub-plots at two autochthonous meadows of the Trisetetum association. These examined six treatments with different cutting regimes (2, 3, 4 cuts per year) and either slurry or solid manure for organic fertilization. Three years of investigation describe changes in coverage of grassland species as well as yield quantity and quality. The results show changes in...

Bælgplanter, herunder de forskellige kløverarter, kan ved knoldbakteriers hjælp (symbiose) optage luftens kvælstof (N2) og derved udnytte denne uudtømmelige kvælstofkilde. Processen er ganske enkelt forudsætningen for at kunne drive økologisk jordbrug, og det har derfor stor interesse at kende størrelsen af N-fikseringen og få et bedre kendskab til de faktorer som har betydning for processen. Derved bliver det muligt at optimere produktiviteten og reducere eventuelle miljømæssige effekter af et givet dyrkningssystem.

The aim of this study was to analyze the influence of silage quality and duration of ensiling to the recovery of infectious larvae of endoparasites. 48 silage bags of different quality were prepaired (gras, gras and earth, gras and silage additive, gras and earth and silage additive). Third larvae of a parasite larvae mixture were added. Larvae were recovered by the methode of Baermann-Wetzel. Significant differences were seen between groups in the larval recovery with more recovery in groups with additional earth. Differences in pH were ambivalent, but samples without added earth were at least numerically better.

Symbiotically fixed nitrogen (N2) is an important input of nitrogen (N) source in many agricultural systems. In spite of this fact, the input of symbiotically fixed N to a particular cropping system is usually not known and exact measurements are costly and laborious. Consequently, there is a demand for an uncomplicated and reliable tool to estimate symbiotic N2 fixation (SNF) in leguminous crops. A simple emperical model is proposed for quantification of SNF in forage legumes under low external input conditions. The model estimates SNF using dry matter yield as input and parameters for (i)N concentration in dry matter and the (ii) proportion of the N in the legume that is derived from the atmosphere. Further, the model includes fixed N not included in the... Tipo: Journal paper Palavras-chave: Pasture and forage crops.

Including forb species in grassland mixtures may secure a more biodiversity-friendly production of biomass. This experiment showed interesting future perspectives in terms of production of low-cost biomass for e.g. biogas production, which can be obtained by reducing the number of cuttings without compromising yield levels. No significant differences in dry matter (DM) yields of chicory, birdsfoot trefoil, yarrow and a 13 species mixture were observed between the situations with four compared to one autumn cut per year. Especially the 13 species mixture showed great potential in terms of yield and suppression of unsown species, for which reasons it should be developed further through knowledge on the species in pure stands.

Organic Eprints Olivo, Clair Jorge; Aguirre, Priscila Flôres. O objetivo desta pesquisa foi avaliar a massa, o teor de proteína bruta da forragem e a taxa de lotação em pastagens de capim elefante em dois sistemas de produção. No sistema convencional, o capim elefante foi plantado em linhas afastadas a cada 1,2m. No sistema agroecológico, o capim foi plantado em linhas afastadas a cada 3m; no espaço entre as linhas, no período hibernal, foram semeados o azevém anual e o trevo vermelho e, no período estival, permitiu-se o desenvolvimento de espécies de crescimento espontâneo. Foram utilizados 150kg de N ha-1 com fertilizantes químico e orgânico para os respectivos sistemas forrageiros. Foram usadas vacas em lactação que receberam complementação à razão de 0,9% do peso vivo. Para determinação do teor de proteína bruta,...

Species-rich swards have received increasing interest due to their focus on ecosystem services, animal welfare and product quality. However, in high-yielding swards the proportion of herbs is often limited and there is little knowledge of their management. Seed mixture composition, cutting frequency, fertilization and grazing/cutting strategies were examined over 4 years in 3 experiments to quantify their effects on herbage yield and botanical composition. Inclusion of herbs in the sward gave similar or higher annual yields but swards established with 100% herbs depended on the presence of a driver species. The effects of management differed between species. Herb content in the sward was significantly related to the proportion of herbs in the seed...

Dynamic simulation models can be useful tools for predicting the residual effect of leys, but only if they have been calibrated and validated appropriately for this particular situation. The BIOMOD project has aimed at expanding, calibrating and validating two Danish dynamic simulation models, namely FASSET and Daisy, for a range of crop rotational situations occurring in organic farming. Here we report on the calibration results for an extensive experiment with residual effect and nitrate leaching following grass-clover leys.

Ano: 2023 The development of organic milk production systems Organic Eprints Weller, R. The main objective of the 4-year project was to provide both qualitative and quantitative information on the development of two contrasting organic dairy systems, including the benefits and limitations of each system and also the opportunities for improving the systems. The first system (SS system) was based on an extensive and sustainable system, with the objective of achieving a high level of self sufficiency and sustainability by minimising the importation of nutrients into the system. Therefore, the cropping rotation for the system included forage crops for grazing and conservation and also cereal crops to provide both grain (for feeding as a concentrate) and straw for bedding.

There is an increasing focus on biodiversity and feed resources for pollinators. However, the integration of these elements into high-yielding temporary grasslands is a challenge. With the main aim of continuous flowering we examined three strategies with four cuts per year, in which the time of the spring cut varied. In total we had 10 different harvest times during the season. This was combined with 12 different species mixtures in two categories. One was high-yielding mixtures composed of perennial ryegrass (Lolium perenne), white clover (Trifolium repens) and red clover (Trifolium pratense), either alone or with either chicory (Cichorium intybus), ribwort plantain (Plantago planceolata) or caraway (Carum carvi).
