SOIL SPATIAL HETEROGENEITY IN VINEYARDS FOR FINE WINE PRODUCTION: PEDOLOGICAL SUPPORT FOR PRECISION VITICULTURE [PDF]
Engenharia AgrícolaSoil spatial variability in vineyards is often underestimated in management planning. This study assessed pedological heterogeneity in a high-altitude vineyard (0.4 ha) by sampling soils adjacent to 68 vines at two depths (0–20 and 20–40 cm) for texture,

Assessing Within-Field Variation in Alfalfa Leaf Area Index Using UAV Visible Vegetation Indices
Agronomy, 2023 This study examines the use of leaf area index (LAI) to inform variable-rate irrigation (VRI) for irrigated alfalfa (Medicago sativa). LAI is useful for predicting zone-specific evapotranspiration (ETc).
