Antibiotics used in animal production are a major source of environmental contamination, since most them excreted manure. However, studies on the impact antimicrobial effects have focused humans and livestock, neglecting environment. The European Union (EU) adopted strategy to prioritise monitoring develop tools make it cost-effective. Our aim was build prioritization tool at national level ide...

Abstract. Purpose. The research is aimed at developing methods for creating highly productive and nutritious pasture agrophytocenoses, adapted to the extreme conditions of arid zone Northern Caspian region. Methods. paper provides an assessment productivity perennial one-species (Agropyron) poly-species (Agropyron, Eutoria, Kochia) agrophytocenoses a five-year period their vegetation, depending...

Soil aeration is a key parameter for sustainable and productive agriculture. The intensification of agricultural activity in Greenland involves land use (LU) LU change, affecting the soil–air phase. combined effects natural compaction (bulk density, ?b), texture (texture uniformity index; TUI), on phase subarctic soils are not well known. This study aims to identify compare main drivers air-fil...

Soil drainage and phosphorus (P) availability are considered indicators of management intensity in pasture-based agriculture supporting livestock. However, microbial adaptations to P-availability according soil class rarely investigated. We hypothesized that well-drained grasslands with high will sustain a distinctive microbiota when compared poorly-drained low-P availability. The relationship ...

Denitrification is mediated by microbial, and physicochemical, processes leading to nitrogen loss via N2O and N2 emissions. Soil pH regulates the reduction of N2O to N2, however, it can also affect microbial community composition and functional potential. Here we simultaneously test the link between pH, community composition, and the N2O emission ratio (N2O/(NO + N2O + N2)) in 13 temperate past...

scientists call pasture a natural eco-system and range is an agricultural eco-system. in this point of view although pasture that was full of plants growing by itself and not growing by human being (pirdashti, 2007; mohgadam, 2005) and two groups of living beings such as human being, plants, domesticated, and not living being like weather, wind, gradient which are effective in making of pasture...

Numerical and spatial components of dispersion, and the activity of pukeko (Porphyrio p. melanotus) in swamp and pasture in coastal Manawatu, New Zealand, are describeed. Pukeko are concentrated in few locations during the autumn population peak, but are widely scattered in spring when the population size is minimum. Flocks are consistently larger in pasture than swamp; those of up to ten birds...

Xiphinema llanosum n. sp. and Trophurus vultus n. sp. are described and illustrated from grass soils in Llanos Orientales, Colombia. Xiphinema llanosum is a bisexual species. The female body length is 2.3-2.7 mm, odontostyle 86-96 mum, and odontophore 58-65 mum long; vulva at 42-47%; anterior ovary is absent; the anterior uterus and oviduct are similar to the posterior branch but slightly reduc...

The objective of this study was to evaluate the effect of herbage allowance on pasture DM consumption by growing European wild boar. An additional objective was to evaluate the influence of pasture consumption on supplemental diet intake and BW gain. A previously sown grass-clover pasture was managed by cutting to obtain an herbage mass equivalent to 1,500 kg/ha DM. Areas of pasture were limite...
