1. Mobile Robotic Soil Moisture Sensing and Mapping for Precision Agriculture in Small-Scale Farming

The 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
