1. Delineation of Agroecological Zones for Rainfed Summer Crops in Eastern UruguayThe delineation of agroecological zones is a key step for understanding spatial variability in crop performance and for supporting the assessment and transferability of agricultural technologies. Even within relatively small regions, strong gradients in climate and soil properties can lead to substantial differences in crop yield potential and stability, particularly in rainfed systems. This study aims to delineate agroecological zones for rainfed summer crops in eastern Uruguay using an inte... D. Gaso, I. Macedo |
2. 3D Spatial Resolution of Nutrient and Isotopic Soil Mapping: A Baseline for Precision Soil ManagementAlthough there is a need to increase agricultural productivity, this must occur without compromising soil health and/or surrounding ecosystems and biodiversity. In Westmorland and Furness, England, a feasibility study is being developed to implement a scientific, collaborative, and interdisciplinary strategy involving farmers, scientists, and environmental authorities. The goal is to optimize nutrient management and promote climate-smart agriculture through evidence-based cooperation bet... G.Y. Sanchez vazquez |
3. Comparative Analysis of Technical and Economic Feasibility of Pepper (Capsicum Annuum) Cultivation Under Artificial Lighting Vs.

4. Towards Precision Agriculture with Electrochemical Sensors for Detecting Dopamine in Plants and FruitsCathecolamines are essential neurotransmitters that regulate the central nervous system of animals, while also acting as direct modulators in plants, coordinating antioxidant responses and ionic balance regulation. Dopamine (DA) is an essential catecholamine not only for animals but also plays a critical regulatory role in plants, acting as a potent antioxidant and growth modulator under abiotic stresses such as drought and salinity or pathogen attacks and helps neutralize free radicals ...

5. Flow Rate and Discharge Coefficient Behavior of Spray Nozzles in a PWM SystemPulse width modulation (PWM) technology has been widely used in variable-rate pesticide applications, allowing flow control by varying the duty cycle while maintaining constant pressure. However, the intermittent operation of the flow may alter the hydraulic behavior of spray nozzles, influencing both the effective flow rate and the discharge coefficient (Cd). In this context, the objective of this study was to evaluate the behavior of flow rate and discharge coefficient of different spray no... B. Costalonga vargas, M.R. Furtado júnior, A.L. Coelho, S.

6. Optimal Hyperspectral Band Selection for UAV-Based Aflatoxin Risk Prediction in Peanut FieldSouth Georgia’s humid subtropical climate and well-drained sandy soils make Georgia the leading peanut (Arachis hypogaea L.) producing region in the United States, accounting for more than half of the nation's production. However, aflatoxin contamination caused by Aspergillus fungi remains a significant concern, posing serious food safety risks and causing substantial economic losses. Rising temperatures and humidity from the climate crisis create ideal conditions for fungi... N. Niva, L. Lacerda, G. Vellidis, S. Maktabi, M. Ardigueri |
7. Soilres: an On-farm, Variability-centred Project to Translate Biodiversity-based Soil Health Innovations into Precision ManagementSOILRES (Multi-Faceted Biodiversity Integration for a Healthy Soil and Resilient Crop Management) is a Horizon Europe project. It aims to improve soil health by a combination of agroecological practices and soil improvers which will be tested in on-farm experiments and monitored with proximal and remote sensors, as well as modelling. On-farm experiments are implemented through six use cases spanning Europe’s major pedo-climatic zones: Atlantic (Denmark), Boreal (Finland), Continental (F... M. Canicatti, D. Cammarano |
8. What 255 Sugarcane Farms and 15,000 Ha Reveal About Sustainable Nutrient ManagementConsidering spatial and temporal variability in agricultural production is a key pathway toward improving sustainability in broadacre systems. Cropping systems under uniform management (UM) assumptions inherently neglect this variability, creating substantial inefficiencies and environmental risks. In Brazil, sugarcane occupies approximately 9 million hectares and underpins a bioenergy sector often cited as contributing to one of the most renewable energy matrices worldwide. However, fertiliz... R. Canal filho, J.P. Molin, L. De goes sterle, V. Ferraz |
9. Machine Learning–driven Insights into Nitrogen Dynamics and Greenhouse Gas Emissions in Potato Production SystemsNitrogen (N) is an essential nutrient for potato vegetative growth, yet it remains one of the most challenging elements to manage in modern agricultural systems. Despite its critical role in crop productivity, excessive or poorly timed N application can lead to significant environmental losses, particularly through groundwater nitrate (NO3-N) leaching and emissions of nitrous oxide (N2O), a greenhouse gas approximately 300 times more potent than CO2. Therefore... B. Javed, A. Cambouris, E. Smith, S. Dandrifosse, N. Ziadi, A. Karam |
10. Crop Production and Nutrient Management with Strip-tillage in the Northern Great PlainsConventional tillage is still the dominant tillage practice in the eastern third of South Dakota (USA). Producers are often facing wind and water soil erosion in this part of the state. Strip-tillage can offer an alternative production option that could lower erosion potential between cash crops, while maintaining the yield potential. In addition strip-tillage allows a same-pass nutrient placement. The research objectives are to compare tillage and fertilizer placement methods in a corn (... P. Kovacs, C. Tesch, N. Passone |
11. Soybean Yield Response to Apparent Soil Electrical Conductivity–based Management ZonesManagement zone delineation is a key strategy in precision agriculture, as it enables a better understanding and managing spatial variability in soil attributes and crop yield. Apparent soil electrical conductivity (ECa) has been widely used as an indirect indicator of soil physical and chemical properties and as a basis for defining homogeneous management zones. The objective of this study was to evaluate soybean yield behavior within management zones delineated using soil ECa.The study was ... E.L. Bottega, Z.B. Oliveira, D. Queiroz, A.
