Growth responses of grass swards to tree-mediated temporal and spatial dynamics of light and temperature in a silvopastoral system
(2024-06-12)Agroforestry can increase the resilience of agriculture to the predicted changes in climate. Alley cropping systems are a form of agroforestry where tree lines are integrated into the agricultural area in regular distances. ... -
Insights into nitrogen fluxes in different dairy production systems in northwest Germany
(2023-08-31)Local nutrient surpluses are a global challenge and pose a risk for ecosystems. Nitrogen (N) is particularly important in this context, as it is a main plant nutrient and necessary for a promoted plant growth in agricultural ... -
The Analysis of Climate-induced Feed Gaps in Arid and Semi-arid Southern African Regions: The Case of The Limpopo Province-South Africa
(2023-05-23)In the southern areas of Africa, climate hazards such as prolonged drought are among the phenomena that have negatively affected the farming systems. In relation to livestock, productivity is constrained by the shifts in ... -
Grass growth, matter turnover and herbage production in temperate silvopastoral systems
(2022-12-07)In recent times, silvopastoral systems gain increasing attention due to their various ecological and economic benefits. They have the potential to be a more sustainable alternative to common intensive land-use practices ... -
Optionen der Grünlandbewirtschaftung im Klimawandel: Bewertung der Weidewirtschaft und Prüfung von Weidelgras, Rohrschwingel und Lieschgras.
(2021-07-23)In regions with a moderate climate, longer and more frequent droughts are to be expected as a result of climate change, which will make it more difficult to grow perennial ryegrass (Lolium perenne). In this thesis it was ... -
Grassland management with horses: Its role in grassland utilization in Germany and the effects on grassland vegetation
(2021-01-19)Grazing is a well known management tool to increase and maintain species richness in grasslands. Generally, livestock grazing enhances sward structural heterogeneity due to dietary choices, trampling, nutrient cycling and ... -
Nutrient Response Efficiencies, Leaching Losses and Soil-N Cycling in Temperate Grassland Agroforestry and Open Grassland Management Systems
(2020-07-01)In recent years, there is an increasing interest in innovative agricultural systems as an alterna-tive to open grassland systems in order to minimize the detrimental effects of intensive pro-duction systems on the environment ... -
Combining remote sensing data at different spatial, temporal and spectral resolutions to characterise semi-natural grassland habitats for large herbivores in a heterogeneous landscape
(2019-11-22)Semi-natural grasslands are ecosystems with high biodiversity. In Europe, such open and half-open areas are a fundamental characteristic of the cultural landscape, originating from and depending on management activities. ... -
Effect of white clover and perennial ryegrass genotype on yield and forage quality of grass-clover and grass-clover-forb mixtures
(2019-05-16)Grass-clover mixtures have shown a higher yield, higher yield stability and higher nutritive value compared to individual species in monoculture. The number and identity of species in a mixture are important factors for ... -
The influence of drought stress on yield and forage quality of grasslands differing in functional composition
(2019-03-04)The present study aimed at unraveling the interacting influences of functional group composition, drought stress and N fertilization on sward productivity and forage quality in old semi-natural grassland in Northern Germany. ... -
Management and drought effects on growth and herbage yield of Tall Wheatgrass (Agropyron elongatum) for biogas production in Central Europe
(2018-07-31)Climate change clearly influences agricultural production. Most scientific studies for climate change in Central Europe predict the scarcity of water and a changed distribution of precipitation that will lead to increased ... -
Management, methods and attitudes concerning grassland farming in Northern Germany
(2017-08-03)Grassland is seen to fulfil a range of functions: Grasslands deliver biomass for livestock and energy production and provide several ecosystem services like biodiversity and wildlife protection, carbon sequestration, water ... -
Weeds in a changing environment
(2015-04-10)In the course of the past decades, various impacts of climate change have been recognized to pose a challenge to arable production systems. Among others, shifts in the species composition of weed communities, particularly ... -
Spatial scale, plant identity and management effects on the diversity-productivity relationship in a semi-natural grassland
(2014-12-18)Present study was aimed at examining the effects of spatial scale, plant identity and management on the relationship between diversity and productivity in an old semi-natural grassland in the Solling uplands, Germany. The ... -
Effects of management on biodiversity and productivity of grazed grassland
(2014-04-30)Grazing is seen as a promising tool to maintain and enhance biodiversity due to the creation of structurally diverse pastures. So far, grassland biodiversity has been studied in relation to various grazing management ... -
Response to disturbance and plant-animal interactions of grassland swards for chicken free-range husbandry
(2013-08-27)The aim of the present study was to evaluate the suitability of fourteen grassland plant species for establishing swards for free-range chicken husbandry. Nine grasses and five forbs which are known for their good performance ... -
Sustainable grassland herbage production under drought stress - the role of plant species number and functional group composition
(2013-06-14)Producing grassland herbage with high yield and good nutritive value is a prerequisite of an efficient ruminant livestock production. Due to climate change, precipitation patterns are expected to vary and the frequency of ... -
Performance of underutilized forage legumes as an alternative to Trifolium repens under drought stress: yield, water utilization and nutritive value
(2013-05-31)Grassland with a high productivity and fodder quality forms the basis for ruminant nutrition. In grassland swards with no or little input of nitrogen (N) from mineral fertiliser or manure, legumes are essential for ... -
Strategien zur Verbesserung der N-Ausnutzung im ökologisch wirtschaftenden Futterbaubetrieb
(2012-12-18)Organic forage and mixed farms often do not utilize their grassland to its full potential. In mixed farms this affects the arable farming as well. By intensifying grassland production (more clover, more cuts), N leaching ... -
Effects of agricultural management and manipulated plant species composition of permanent grassland on productivity and sward structure
(2012-05-04)The relationship between biodiversity and ecosystem functions of grasslands has received increasing attention in recent years. Scientists have sought to disentangle this complex relationship by sown biodiversity experiments ...
