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. ... -
Local and landscape threats to bee and wasp populations in agricultural landscapes
(2023-12-01)The transformation and intensified use of the agricultural landscape in central Germany in the past decades has led to the fragmentation and loss of semi-natural habitats, threatening biodiversity including insects. Bees ... -
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 ... -
Using smart farming technologies to improve the sustainabilty of livestock grazing systems
(2023-01-12)Semi-natural grasslands, which contribute to a wide range of ecosystem services, such as soil erosion control, water storage and carbon storage, are severely threatened by both intensification and complete extensification, ... -
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 ... -
Ecosystem services driven by soil biota in agricultural landscapes - Effects of farm-based soil management practices
(2022-08-24)Diversity, abundance, and biomass of soil biota depend on the biotic and abiotic characteristics of the soil environment and are essential for the provision of important ecosystem services. Agricultural systems are shaped ... -
The role of stable sward height patches for the productivity, herbage intake and nitrogen cycling of cattle pastures differing in stocking rate
(2022-07-18)Extensively managed grasslands are multifunctional. Especially low-intensity grazing is known to be beneficial for biodiversity outcomes as well as for numerous other ecosystem services, such as carbon sequestration. The ... -
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 ... -
Investigating resource competition in cereal-legume intercropping systems
(2020-10-12)Intercropping has long been a key crop production strategy for low input farming systems, such as those of smallholders, and organic farmers, where two or more crops are used to allow for the complementary use of resources, ... -
Spatial analysis of crop rotation practice in North-western Germany
(2020-09-24)The aim of the present study was to detect patterns of crop rotation in an agricultural region in the North-western part of Germany. It was analysed if and how the spatial distribution of the crop rotation patterns depends ... -
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. ... -
Züchterische Analyse von acht Winterackerbohnengenotypen für den Gemengeanbau mit Winterweizen
(2019-10-30)Within the framework of the IMPAC³ project, eight winter faba bean genotypes (experimental inbred lines) and three winter wheat cultivars approved in Germany were cultivated in the domain referred to as "arable land". These ... -
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. ... -
Biomass, root distribution and overyielding potential of faba bean/wheat and white clover/ryegrass mixtures
(2019-02-11)Mixtures of legumes and non-legumes are often characterized by higher grain and biomass yields compared to their pure stands. Complementarity between plant species is assumed to be the major driver behind this aboveground ... -
Effect of the potassium and magnesium nutrition on potato (Solanum tuberosum L.) tuber quality and plant development
(2018-10-17)Knowledge regarding the importance of potassium (K) and magnesium (Mg) for potato plant development and tuber quality is limited. K and Mg are nutrients, besides other crucial roles, for photosynthesis and the partitioning ... -
Effect of plant and animal functional traits on nutrient cycling in low-input pastures
(2018-09-05)Excrements of grazing animals play a key role for nutrient cycling in grazed grasslands. So far, most studies on nutrient cycling in pasture systems were performed using simulated excrement patches under simulated grazing ... -
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 ...
