Abstract

Biochar’s nutrient retention paired with rhizobacteria’s nitrogen-fixation may improve the quality of soils throughout the US. This study’s purpose was to test whether the combination of biochar and Rhizobium leguminosarum would lead to healthier soils and greater plant growth in poor soils. It was hypothesized that combined additions of biochar and Rhizobium leguminosarum in suboptimum soils would lead to greater soil nitrates and phosphorus and higher Eruca sativa growth rates than separate or no introductions. The experiment was first split into four groups, each with fifteen trials: Control, Biochar, Rhizobacteria, and Combined. Biochar or Rhizobium leguminosarum was added to each applicable trial, and Eruca sativa seeds were planted and stem lengths measured every other day over 16 days. Soil nitrates and phosphorus were tested before and after experimentation. The ANOVA[F(3, 305)=9.92, p<0.001
