1. Mobile Robotic Soil Moisture Sensing and Mapping for Precision Agriculture in Small-Scale FarmingThe spatial variability of soil moisture is a key factor for efficient irrigation management and agricultural productivity, particularly in small-scale farming systems where access to precision agriculture technologies remains limited due to cost and operational complexity. This study presents the development and preliminary evaluation of a robotic sensing system for georeferenced soil moisture data acquisition, focusing on spatial mapping in small agricultural areas. The proposed system... D.H. Hall, M. Hosser, R.L. Machado, R. Galli, A.L. Machado |
2. Estimation of Sugarcane Yield Based on Phenological Feature Extraction from Time-Series Sentinel-1 Images and Machine LearningDue to frequently rainy and cloudy weather in the main sugarcane production areas, optical remote sensing data are often missing, and the conventional yield estimation models based on radar remote sensing data lack the support of crop growth mechanisms. This study aims to explore a new yield estimation method for capturing the key dynamic growth features of sugarcane under all-weather conditions. This study takes the sugarcane yield in the dominant area of sugarcane production, Guangxi Zhuang... H. Xue, X. Xu, G. Yang, Z. Xu, S. Xiaoyu, L. Chen |
3. Temporal NDRE Dynamics from UAS Imagery to Characterize Rice Drought ResponseCharacterizing drought resilience in rice remains challenging under increasing climate variability. Drought tolerance is a complex and dynamic trait that is difficult to quantify using traditional field phenotyping approaches, particularly when responses vary with time. High-throughput temporal phenotyping with unmanned aircraft systems (UAS) enables monitoring of canopy reflectance dynamics associated with water stress across the growing season. This study evaluated whether temporal... |
4. Soil Factors Affecting Severity of Verticillium Wilt in Kiwifruit (Actinidia Deliciosa)Verticillium wilt, caused by the soil-borne fungal pathogens Verticillium albo-atrum and V. dahliae, represents a highly destructive vascular disease in kiwifruit, with pronounced impact on gold kiwi (Actinidia chinensis). The disease manifests as acute wilting, shoot dieback, foliar necrosis, and, in severe cases, complete plant mortality. Conversely, green kiwi (Actinidia deliciosa) exhibits greater resistance to Verticillium wilt; while the disease does not typically cause vine death, it adversely... H. Poblete, R.A. Ortega, M.M. Martinez, I. Ortega |
5. Spatial Variability of Biochemical Soil Properties and Its Relationship to Physical and Chemical Properties and Vegetation IndicesBiochemical soil properties, particularly enzymatic activity, are increasingly recognised as important indicators of soil quality within the context of regenerative agriculture. However, limited information exists regarding the spatial variability of these properties in fruit orchards at varying scales, as well as their relationships with other soil characteristics, such as texture and soil organic matter, and with plant quality. This study aimed to investigate the spatial variability... R.A. Ortega, M.M. Martinez, H. Poblete, I. Ortega |
