Importance of supplying dairy cows with essential fatty acids (EFA) and conjugated linoleic acids (CLA) during the transition period on metabolism and health
(2022-08-04)Ketogenesis and steatosis are common sequelae of the severe mobilization of fat reserves necessary at the onset of lactation when the energy expenditures for milk and maintenance exceed the energy provided by voluntary ... -
Soil microaggregates as habitat for microorganisms
(2022-07-27)Aggregation of soil particles is one of the most characteristic features of terrestrial soils and crucial for their functionality. Despite the high relevance of soil aggregates, only little is known about their genesis and ... -
Green futures for whom?: Traveling models as tools of legitimization in Kenya's future making
(2022-07-05)Development concepts that promise growth in the economy while safeguarding the environment have progressively become significant in the recent past in the global south countries. These concepts are framed and argued to ... -
Remineralizing soils? The agricultural usage of silicate rock powders in the context of One Health
(2022-06-29)The concept of soil health describes the capacity of soil to fulfill essential functions and ecosystem services. Healthy soils are inextricably linked to sustainable agriculture and are crucial for the interconnected health ... -
The serum proteome and metabolome of dairy cows clustered for body fat content from a large dairy herd
(2022-06-20)The transition from late pregnancy to early lactation implies metabolic and endocrine changes for accomplishing the adaptation to the rapid increase of milk production. Voluntary feed intake can usually not cover the energy ... -
The genetic and molecular architecture controlling flowering time in interaction with the environment in winter wheat
(2022-06-22)The time of flowering is a key factor for global adaptability to diverse conditions and a critical agronomical factor for successful reproduction. This high potential is resulting from a natural variation that has remained ... -
Role of root plasticity in response to soil compaction in sorghum
(2022-06-17)Compacted soils limit crop production and affect millions of hectares of agricultural land globally. Plants vary in tolerance to soil compaction and roots express various plastic responses. Unfortunately, the importance ... -
Improving animal welfare on dairy farms with special emphasis on calf management
(2022-06-17)Livestock welfare, including dairy cows and calves, has gained importance for society, politics, and agriculture over the last decades. Providing kept animals with a high level of animal welfare requires the implementation ... -
Miscanthus as primary feedstock for growing media in soilless cultivation
(2022-06-03)Dry biomass of miscanthus crop (Miscanthus spp.) is a promising feedstock for soilless substrates in the temperate regions because of its high biomass production under low-input and ecosystem services. The objectives ... -
Disseminating sustainable intensification practices: Empirical evidence from Ghana
(2022-06-02)Adoption of sustainable intensification (SI) of agricultural practices is essential for increasing food production in more sustainable way. Dis-adoption of agricultural technologies is pervasive among smallholder farmers ... -
Ecological sanitation via thermophilic co-composting of humanure and biochar as an approach to climate-smart agriculture
(2022-06-01)Lack of basic sanitation and appropriate waste management, limited access to mineral and organic fertilizers, and land degradation are major public health and food security challenges, particularly in developing regions ... -
Towards improved process representation for modelling CO2 and H2O fluxes of crops
(2022-05-30)Exchange rates of CO2 and H2O between vegetation and the atmosphere are strongly linked by stomatal functions and crop growth. Crops under drought stress show different responses, such as stomatal ... -
Patterns of Urbanization and Economic Development: Evidence from household surveys in Ethiopia
(2022-05-17)Countries in sub-Saharan Africa (SSA) are urbanizing at an unprecedentedly fast rate. This trend has the potential to affect the welfare of households by altering the degree of urban proximity as well as the size of the ... -
Cultivation and utilization of Hydrangea macrophylla subsp. serrata as feedstock for dihydroisocoumarins and its quality-assessment through non-invasive phenotyping
(2022-05-09)New and innovative bio-based products of today are regularly inspired by a long-known and traditional use of plants. One such example is the taste modifying phyllodulcin (PD), a dihydroisocoumarin (DHC) only present in ... -
Advances in technology evaluation and decision support studies using bio-economic farm models
(2022-04-11)The use of so-called bio-economic farm models makes it possible to determine the most cost-effective adaptation strategy to novel policy measures and to evaluate whether the use of new technologies can be economically ... -
The hidden risk of conventional floodplain mapping: Diagnosis in Cali, Colombia
(2022-04-05)Flood hazard maps display the geographical areas inundated by water bodies after extreme rainfall events take place, helping governments focus their efforts and resources on performing works to mitigate disasters produced ... -
Identification, characterisation, and evaluation of bioactive plant-based compounds for the sustainable stabilisation of food packaging materials
(2022-04-05)Typically, plastic packaging materials are produced using additives, like e.g. stabilisers, to introduce specific desired properties into the material or, in case of stabilisers, to prolong the shelf life of such packaging ... -
Yield, productivity and technical gaps that limit the cotton agricultural production system in the Colombian Caribbean
(2022-03-29)This thesis contributes to understanding factors related to production situations in agricultural systems of the Colombian Caribbean using decision analysis. Decision analysis has numerous advantages when it is used for ... -
Breeding progress for drought tolerance and nitrogen use efficiency in winter wheat (Triticum aestivum L.)
(2022-03-28)Drought is the major abiotic stress factor limiting agricultural production in arid, semi-arid as well as in temperate regions around the world, whereas nitrogen (N) is one of the most important nutrients for crop production. ... -
High-Throughput Phenotyping of Photosynthesis Traits in Durum Wheat Under Drought Stress Using Light-Induced Fluorescence Transients
(2022-03-24)Agriculture in the twenty-first century faces the double challenge of feeding a growing population in a changing climate. Food security will increasingly rely on the active release of stable high-yielding cultivars with ...
