Rebuilding Soil Ecosystems for Improved Productivity in Biosolarized Soils

Figure 3

Treatments: bare control with no amendment (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). B and LB treatments must be analyzed separately. While they have had day 0 nitrogen subtracted from their mineralized nitrogen values, because there was no N added to the pots, they have not been divided by any amount and are therefore on a much larger scale than the other treatments. Different lowercase letters indicate significant differences at day 7 of incubation. Different capital letters (A&B for amended treatments; Q&R for bare treatments) indicate significant differences at day 28 of incubation (α = 0.10).
