Alpha diversity indices (Sobs, Ace, Shannon, and Simpson) for the soil microbial community following exposure to sulfur for 7, 14, 30, and 60 days. The letters “P” and “E” denote the prokaryotic and eukaryotic microbial communities, respectively. The letter “S” represents the application of sulfur spray. No statistical significance was found for discrepancies between the sulfur treatment and CK using Welch’s t-test (P < 0.05)
