Treatments applied to biosolarized soils: bare control with no amendment and no LEM inoculant (B), bare with LEM inoculant (LB), compost at 50 kg·N·ha⁻¹ and at 135 N·ha⁻¹ with and without LEM (C50, C135, LC50, and LC135), respectively, and mineral fertilizer at 50 kg·N·ha⁻¹ and at 135 N·ha⁻¹ with and without LEM (M50, M135, LM50, and LM135). Different letters indicate significant differences within columns (α = 0.1).
