Association between soil properties and Grapevine Leaf Stripe Disease (Esca Complex) symptom expression. Part I: soil physical, hydrological and chemical characteristics

In a 1.75-hectare Vitis vinifera Cabernet Sauvignon vineyard in Tuscany, Italy, GLSD symptom recurrence is spatially linked to soil properties, including available manganese (4.5–4.8 vs 14.7–14.8 mg/kg).

• Why it matters: The work addresses a gap in how soil physical, hydrological, and chemical variation relates to foliar symptom expression in GLSD, a complex disease with heterogeneous field patterns.
• What they did: Using EMI proximal sensing and kriging-based five-year GLSD recurrence maps, the study compared high- and low-recurrence sectors, then excavated one soil profile per sector for pedological and physicochemical characterization.
• The result: Low-recurrence sectors showed clay loam to silty clay loam textures, higher AWC, alkaline pH, and lower available manganese (4.5–4.8 mg/kg), while high-recurrence sectors had sandy textures, subalkaline pH, deeper roots, higher nitrogen/organic matter, and higher manganese (14.7–14.8 mg/kg).
