Root trait response to drought, recovery, and P deficiency of upland rice
(2025-01-16)Phosphorus deficit and intermittent drought can cause high-yield reductions in rice (Oryza sativa L.) production. Large differences in tolerance of low P availability and drought resilience were found in the upland rice, ... -
Importance of root-soil contact conditions for the microbiota in the soil-rhizosphere-plant continuum
(2025-01-14)The contact zone between a root and the surrounding soil mediates processes such as nutrient and water uptake and the interaction with microorganisms. Despite the importance of the contact zone, there is a lack of understanding ... -
Data-driven Image Generation for Crop Growth Modeling
(2025-01-09)Crop growth models play a crucial role in agriculture as they help to understand how crops grow and thrive. They allow farmers to predict how much harvest they can expect, which is important when planning, storing, and ... -
Molecular mechanisms of Pseudomonas-enhanced plant performance in Brachypodium under limited nitrogen
(2025-01-08)While the world population is increasing, the use of nitrogenous fertilizers has become obligatory to increase yields to meet the global food demand. Overuse of synthesized N fertilizers does not only negatively impact the ... -
Analyzing Crowd-Sourced Trajectories to Infer Routing Preferences of Cyclists
(2025-01-06)In the last decade, the activities of many volunteers have resulted in almost complete representations of street networks and large sets of trajectories. The latter have primarily been collected by recreational sportspeople ... -
Development of an experimental gravimetric geoid model for Nigeria
(2024-12-17)Due to the increasing demand for precise mapping, surveying, geodesy, and large-scale infrastructure projects, the establishment of a precise national geoid model for Nigeria is essential. In this doctoral thesis, an ... -
Evidence on the role of context for agricultural innovation and conservation
(2024-12-13)This dissertation aims to explore how agricultural innovation and policies can make agri-food systems more sustainable by assessing impacts and diffusion patterns of innovations, as well as policy impacts across geographic ... -
Vision-Based Semantic Scene Understanding for Agricultural Robots
(2024-12-13)An essential task of agriculture has always been the production of food, feed, and fiber for an ever-growing world population with constrained arable land available. In the past decades, this challenge has been primarily ... -
Chopped Miscanthus biomass for soil organic matter build-up and evaluation of nitrogen and carbon dynamics in arable farming systems
(2024-12-12)Arable farming practices affect soil C and N dynamics and thus have a crucial impact on global climate change and on aquatic and terrestrial ecosystems. Soil nutrient cycling is driven by soil microbial biomass, making ... -
A global drought monitoring framework using GRACE/-FO data assimilation
(2024-12-09)Extreme climate phenomena like droughts can lead to a shortage of available water resources that in turn can cause serious consequences such as famines. Monitoring of extremes is extremely important, and past research ... -
Beyond Zooming: Models and Algorithms for Mobile Maps with Extended Interaction Techniques
(2024-12-05)This thesis focuses on the development and evaluation of novel interfaces for the presentation of large and detailed geographic data sets on mobile devices. Especially when the density of information is high, a major ... -
Deep soil carbon accrual after land restoration in the Atlantic Forest, Brazil
(2024-11-28)Soils play a crucial role in the global carbon cycle, not only by storing most of terrestrial carbon but also by actively participating in carbon sequestration and emission processes. Reliable estimates of soil organic ... -
Retrieval of information and data products for calibration, validation and spatial-temporal analyses from automated field spectrometers
(2024-11-25)Intact ecosystems are the basis of human food security, air quality and provide naturally re-growing resources. Adaptive ecosystem management in the face of climate change requires detailed and continuous data about the ... -
3D Reconstruction of Plant Roots from MRI Images to Advance Root-Soil Systems Modelling
(2024-11-14)<strong>Background and Motivation:</strong> Roots are of particular interest for the efficient use of nutrients and water by plants. Therefore, the optimization of root system architecture (RSA) offers large potential in ... -
Phenotypic evaluation of wild Silphium perfoliatum L. accessions to create a breeding basis for material use
(2024-11-08)Cup plant (<em>Silphium perfoliatum</em> L.) is a promising herbaceous perennial for biomass production. In Germany, <em>S. perfoliatum</em> is mainly grown as a substrate for biogas reactors. Aside from the plant being ... -
Effects of alternate wetting and drying irrigation on rice productivity in Burkina Faso
(2024-10-18)Irrigated systems play a critical role in meeting the growing demand for rice (Oryza sp.) and ensuring global food security. In semi-arid regions of West Africa, with emerging water scarcity driven by rapid population ... -
Nutrient remediation from wastewater by Algal Turf Scrubber (ATS) and evaluation of ATS biomass as fertilizer
(2024-10-17)The increasing discharge of nutrient-rich wastewater into natural water bodies poses a severe environmental challenge, demanding innovative and cost-effective solutions for efficient nutrient removal and recovery. This ... -
Das Bioenergetische Profil präimplantativer Rinderembryonen - Spezifische Effekte der In vitro Kultivierung und der Kryokonservierung
(2024-10-08)Ein beständiges Thema in der In-vitro Produktion (IVP) von Rinderembryonen ist die beeinträchtigte Entwicklungskompetenz. Diese lässt sich durch eine verminderte Kryotaug-lichkeit und geringeren Implantationsraten nachweisen ... -
Effects of mixing multiple spring wheat and faba bean cultivars in variable densities and environments
(2024-10-02)Intercropping, the practice of cultivating two or more crop species together, is widely recognized as a sustainable crop production system. This approach is valued for its ability to enhance production, stabilize crop ...
