Special Issue Information

Dear Colleagues,

Over recent decades, sustainable farming has increasingly relied on new agricultural technologies and precision agriculture to enhance efficiency and environmental responsibility. Advances in geospatial data, sensors, and computational tools have transformed how we monitor and manage soil, vegetation, and production systems, enabling more accurate decision-making and promoting sustainable agricultural practices.

From this perspective, this Special Issue, titled “Sustainable Farming: New Agricultural Technology in Precision Agriculture”, will bring together research contributions that explore the integration of technological, analytical, and environmental dimensions in modern farming. The articles selected for this Special Issue present advances in the acquisition, processing, and interpretation of spatial data, highlighting how geoinformation and computational models can improve the monitoring and management of productive areas.

The main themes include the following:

  • The integration of multisource data for agricultural decision-making;
  • The use of satellite and drone imagery, as well as sensor networks, for crop and soil analysis;
  • Development of algorithms and models for spatial data interpretation;
  • Digital platforms and software supporting the implementation of precision agriculture;
  • Geospatial and temporal analysis applied to productivity and sustainability;
  • Artificial intelligence, big data, and machine learning techniques applied to agricultural optimization.

This Special Issue will promote the exchange of knowledge among researchers and professionals focused on advancing sustainable farming through emerging agricultural technologies and precision agriculture. By emphasizing innovations that integrate environmental responsibility, technological development, and geospatial intelligence, the journal reinforces its mission to disseminate scientific contributions that support more efficient, resilient, and sustainable agricultural systems.

Maize cultivation in tropical Oxisols during the second growing season faces significant climatic risks, where spatial heterogeneity in soil water retention often dictates economic viability. This study integrated a trimodal sensing approach, combining multispectral, thermal, and LiDAR data, with proximal physiological measurements to map isohydric responses and yield variability. Conducted in the Brazilian Cerrado, the research monitored a one-hectare maize field using UAV-based sensors alongside ground truth evaluations of gas exchange, leaf water potential, and soil moisture. Results revealed high yield variability (6.6 to 13.4 Mg ha−1) primarily governed by clay content-mediated water availability. Maize exhibited strict isohydric behavior, maintaining homeostatic leaf water potential through preventive stomatal closure, which limited CO2 assimilation in zones with lower water retention. A significant statistical decoupling was observed between plant height and final grain yield, as water stress impacted reproductive stages more severely than vegetative growth. Furthermore, the Temperature Vegetation Dryness Index (TVDI) served as a robust proxy for biomass vigor rather than mere water deficit. These results confirm that yield variability in tropical Oxisols was not a product of hydraulic failure, but rather a consequence of carbon limitation necessitated by the crop’s conservative hydraulic management to maintain leaf water potential within safe thresholds.
