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 ... -
Assessing the compatibility of genotypes in the rice—Magnaporthe oryzae interaction by hyperspectral imaging
(2024-10-01)The optical properties of plants are valuable indicators of their health and can be used to detect, monitor, and characterize both biotic and abiotic stresses. Spectral techniques like hyperspectral imaging (HSI), have ... -
Global and experimental evidence on the adoption of innovations and robotics for sustainable crop production
(2024-09-26)Agricultural innovations in general and smart farming technologies (SFT) in particular, can mitigate the negative environmental impacts and risk inherent to modern agricultural practices while increasing productivity and ... -
Prokaryotic colonization of soil during early-stage aggregation and of soil microaggregates
(2024-09-25)Soil is a complex mixture of minerals, gas, water and organic materials that assemble into aggregates and define pore spaces, therewith providing connective and isolated habitats for microorganisms. The soil microorganisms ... -
Grape phenolic maturity: Dynamics of polyphenol-polysaccharide interactions and the impact of grape seeds
(2024-09-24)Red wines contain various polyphenols that significantly impact their sensorial characteristics, making polyphenol extraction crucial for winemakers. Polyphenols are extracted from grape berries during maceration and ... -
