Methane is a major constituent of greenhouse gas (GHG) emissions from ruminants, and mitigation strategies are needed to alleviate this negative environmental impact while maintaining the other benefits grazing systems. Forages containing plant-specialized metabolites (PSM), particularly condensed tannins, may help reduce enteric methane (CH4) emissions. However, information on in vivo CH4 cows mixtures that contain bioactive herbs scarce. Accordingly, study compared binary mixture perennial...

There is a pressing need to support farmers' decisions on grassland renovation, based sound scientific evidence regarding its effects productivity, herbage quality and soil organic carbon stocks. To quantify these long-term experiment with grass/white clover swards was set up at the Lindhof research farm in Northern Germany 1995. Treatments included control plots of undisturbed as well 10 renovations starting after (2005) years repeated different times until 2019, without addition slurry...

Land-use extensification by shifting from conventional to organic arable farming is often discussed as a measure for reducing greenhouse gas (GHG) emissions agricultural land. Doubts about the benefits arise when are calculated per product unit, particularly where high yields possible under management. Among non-CO2 GHG emissions, nitrous oxide (N2O) main contributor land and controlled soil type, environmental conditions In order investigate how land-use change would perform highly...

For arable stockless farming systems, the integration of catch crops (CC) during fallow period might be a key for closing nitrogen (N) cycle, reducing N leaching and increasing transfer to subsequent crop. However, despite considerable research efforts, fate in such integrated systems remains unclear. To address this, two-year field experiment was carried out northern Germany with different CC, including frost-tolerant frost-killed CC. The started following ryegrass/red clover ley, which...

Grasslands are crucial for sequestering carbon underground, but disturbances like ploughing can lead to significant soil organic (SOC) loss as CO2, a potent greenhouse gas. Thus, managed grasslands should be maintained minimize GHG emissions. A field study was carried out investigate how varying sward diversity influences respiration following the of temporary grassland. This investigated extent CO2 emissions from different species mixtures immediately after ploughing, well C losses when...

Abstract. A large share of peatlands in northwestern Germany is drained for agricultural purposes, thereby emitting high amounts greenhouse gases (GHGs). In order to quantify the climatic impact fen soils dairy farming systems northern Germany, GHG exchange and forage yield were determined on four experimental sites which differed terms management drainage intensity: (a) rewetted unutilized grassland (UG), (b) intensive wet (GW), (c) moist (GM) (d) arable cropping (AR). Net ecosystem (NEE)...

The effects of climate change on agricultural ecosystems are increasing, and droughts affect many regions. Drought has substantial ecological, social, economic consequences for the sustainability land. Many regions northern hemisphere have not experienced a high frequency meteorological in past. For understanding implications grassland, analysis long-term data provides key information relevant improved grassland management strategies. Using weather production from permanent site, our aims...

Intensive confinement (IC) systems for dairying have become widespread during the last decades. However, potential advantages of alternative such as full-grazing (FG) or integrated dairy/cash-crop (IFG) with regards to better provision ecosystem services are widely discussed. To investigate performance and environmental impacts, we compared four prevailing dairy using an on-farm research study. The farm types differed in their share pasture access quantity resource inputs: (i) IC a high...

Abstract The study investigated how the concentration and composition of purified tannin extracts, at various inclusion rates, affect ruminal in vitro fermentation parameters. Tannin extracts were isolated from four different forage species: birdsfoot trefoil ( Lotus corniculatus) , sulla (Hedysarum coronarium), big (Lotus pedunculatus), salad burnet Sanguisorba minor ). Plants by Sephadex LH-20 gel chromatography analyzed UPLC–ESI–MS/MS. results showed a large variation among species terms...

Yield increases in forage maize (Zea mays L.) NW Europe over time are well documented. The driving causes for these, however, remain unclear as there is little information available regarding the role of plant traits triggering this yield progress. Ten different hybrids from same maturity group, which have typically been cultivated Northwest Germany 1970 to recent and thus representing breeding progress four decades, were selected a 2-year field study northern Germany. Traits that...

High input dairy farms that are located on sandy soils in northwest Europe predisposed to substantial nitrate leaching during a surplus of winter precipitation. Leys within integrated crop-livestock systems play an important role soil fertility, C sequestration and N mineralization potentials. Therefore, leys feasible option can be utilized reduce local losses the environment, especially following maize grown for silage. We hypothesize grass-clover ensure low even when grazed intensively....

(1) Land use intensification has led to serious declines in biodiversity, including forage production systems for dairy cows. Agri-environmental schemes, such as enriching grasslands floral species, were shown be an effective tool promote biodiversity higher trophic levels. Here, we studied innovative pasture-based system with floral-species-enhanced temporary grasslands, respect the effect on wild bee abundance and species richness. (2) We three grass-clover mixtures perennial ryegrass...

The integration of cover crops (CCs) in low-input systems is a widely adopted practice to re-capture surplus nitrogen (N) and avoid excessive losses the environment by leaching or N2O emissions. Closing N cycle within an agricultural system therefore economically beneficial lowers negative impact inorganic on soil water bodies. However, it debated if pollution swapping occurs some extent emissions increases as result decreased leaching. An experiment was conducted systematically evaluate...

Effective nitrogen (N) management is essential for minimizing fertilizer nutrient losses and maximizing N use efficiency. This study, conducted over two years on permanent grassland sites in Schleswig-Holstein, Germany, explored the effects of urea treatment with a urease inhibitor digestate acidification N-cycling yield performance temperate maritime context. Micro plots within these grasslands received varying rates via acidified (with sulphuric acid) or non-acidified (biogas residues),...
