Figure 5. Effect of application of biochar and PGPR on soil pH, EC, MBC, and K+/Na+ ratio in soil.
Effect of biochar and three PGPRs on (A) soil pH, (B) EC, (C) soil microbial biomass carbon, and (D) K+/Na+ ratio in soil in optimum and limited moisture conditions. Error bars represent standard errors of means (n =3). Letters on top of bars represent significant difference, at 95% confidence interval, among means based on a three-way analysis of variance.
