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. Protected EnvironmentContemporary agriculture is undergoing a technological disruption marked by the transition from natural biological dependence to an industrial precision science. At the heart of this shift, the cultivation of pepper (Capsicum annuum) in Controlled Environment Agriculture (CEA) settings utilizes artificial lighting to transform electromagnetic radiation into a programmable input, eliminating solar variability. This study conducted a comparative technical and economic feasibility analysis betwe... L. De arruda viana, A. Luiz de carvalho, R. Ivo soares avelar |
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 |
