1. Results from a Scoping Review: the Role of Autonomous Mechanical Weeding Robots in Climate-smart Soil Management The growing demand for sustainable agricultural practices has driven advancements in digital agricultural technologies, which is also reflected in the emerging development and market release of agricultural field robots in the last decade. Climate-smart sustainable soil management plays a key role in sustaining soil functions related to productivity, water and nutrient cycling, biodiversity and long-term resilience. The integration of autonomous field robots, for which mechanical weeding is currently... K. Grahmann, L. Rohlmann, L. Thielemann, A. Roy, C. Weltzien
2. Do Precision and Climate Concerns Shape Fertilizer Usage Proportions? Evidence from Denmark Farmers are constantly facing pressure to enhance crop productivity while minimizing environmental and climate impacts through efficient input management. In Denmark, because of concerns over nitrogen leaching, greenhouse gas emissions, and water quality degradation, there are tight regulations to fertilizer use. This makes precision farming technologies a key to the efficient management of nutrients through site-specific input application based on crop and soil variability. However, adoption... N.

3. Economic performance of Robotic Applications in Field Crop Farming: Examples from Four European Case Studies This paper presents cost benefit analysis of robotic applications in field crop farming based on case studies from an EU project called ROBS4CROPS with pilot cases situated in Loire valley in France, Corinth in Greece, Catalonia in Spain and Oldambt in the Netherlands. The cases form France and The Netherlands focus on mechanical weeding in vineyards and sugar beet, respectively. The ones in Spain and Greece deal with robotic spraying of crop protection chemicals in apple orchards and table grapes,... T.W. Tamirat, S.M. Pedersen Download paper
4. Sun-view Geometry Causes Hotspot Effect in UAV Imagery During Summer in Tropical Regions High-resolution imagery acquired by Unmanned Aerial Vehicles (UAVs) is essential for remote sensing applications. However, the high solar elevation around noon during summer in tropical regions produces a hotspot effect when the camera is mapping at nadir. The sun-view alignment generates a bright spot in each image acquired during the flight, which significantly changes the digital number and, consequently, the estimated surface reflectance. The objective of this research was to analyze the presence... W. Maes, L. Rodrigues , A.M. Tommaselli, R.P. Silva, V. Carreira
