Summary: In this study, LiDAR technology was used to map a commercial wheat paddock to assess spatial variability of crop biomass, showing significant differences in crop biomass across the field. The correlation between crop biomass and LiDAR-derived crop height was strong, indicating the potential of LiDAR for large-scale operations to support site-specific management. The results suggest that LiDAR technology may be more effective than spectral sensors in capturing crop biomass variability.

Summary: This study evaluates regression models of spectral indices in capturing N uptake using hyperspectral ground-based and multispectral unmanned aerial vehicles (UAV). It suggests that solely using commonly used statistical measures is not sufficient for an agronomic evaluation and agronomically based detection limits should be considered in addition to common statistical measures in the spectral assessment of wheat N uptake.

Summary: This study aims to evaluate the accuracy of mobile in-field fluorescence sensor measurements in quantifying nitrogen indicators variability in maize canopy during early growth season. The results showed that fluorescence sensor can successfully differentiate the variability among different nitrogen treatments, and the accuracy is higher at the V9 stage. When combined with machine learning model, fluorescence-based indices can estimate canopy nitrogen indicators at different growth stages. Mobile fluorescence sensing can accurately determine canopy nitrogen variability in early growth stages of maize, assisting farmers in optimal nitrogen management.

Summary: Deep Learning (DL) is transforming weed detection by integrating ground and aerial-based technologies to identify weeds in still images and real-time settings. A review of 60 technical papers on DL-based weed detection found that transfer learning is a widely adopted technique, custom designed neural networks are less focused on, and no specific model has achieved high accuracy on multiple field images. The review also highlighted the lack of research in optimizing models for resource-constrained devices and exploring ways to design efficient models with less training hours and parameters.

Summary: Assemblage thinking is a valuable approach in studying critical aspects of food and farming, especially in the research of precision agriculture. This paper investigates the tinkering practices of farmers and the role of support networks in making precision agriculture workable in Australia, the Netherlands, and France. The analysis reveals three key forms of tinkering - disconnection, experimentation and trial-and-error, and trade-offs and compromises - and their effects on farmer agency. The findings highlight the importance of a tinkering lens in understanding the deliberate assembling practices and their impact on farmers in implementing precision agriculture.

Summary: This article reviews the applications of remote sensing technologies in precision agriculture and examines the different uses of conventional satellites and unmanned aerial vehicles (UAVs) for data collection. It also provides a detailed overview of how the collected data have been utilized in precision agriculture. Modern UAVs offer several advantages over traditional satellites in terms of data collection and analysis. Precision agriculture is a complex subject, and stakeholders such as practitioners, researchers, and policy planners need to consider the diverse value chain involved.

Summary: The study revealed the advantages of organic agricultural systems over conventional systems in terms of soil quality indicators, such as higher microbial biomass carbon and similar potassium, bulk density, aggregate stability, and total carbon. Grazing regime and changes in the proportion of temporary grass-clover leys in crop rotations have a significant impact on soil quality, and mixed farming systems may be crucial for delivering multifunctional agricultural ecosystems.

Summary: This study compared the impact of conventional and organic agricultural systems, grazing regimes, and proportions of short-term grass-clover leys on soil carbon stocks and distribution among soil organic matter fractions. Results showed no difference in soil carbon stocks between systems, but conventional systems had higher carbon content at a shallower depth. Increasing the proportion of grazed leys led to higher soil carbon stocks and increased content of specific carbon fractions. Longer grazed leys were especially beneficial for certain carbon fractions under the conventional system.
