Soil physicochemical properties evaluation under long-term HDPE mulch application in a Vaccinium virgatum plantation

Quantification of soil physicochemical properties in a long-term field experiment assessing the effects of HDPE mulch application in a Vaccinium virgatum (‘Centra Blue’) plantation in southern Portugal. Soil samples were collected at 0-20 cm depth and analyzed for texture, pH, electrical conductivity, organic matter, organic carbon, macronutrients (P₂O₅, K₂O, Mg), exchangeable cations (Ca²⁺, Mg²⁺, K⁺, Na⁺), and micronutrients (Fe, Mn, Zn, Cu, B)
