1.1 Microbes in the soil could be beneficial to plants and one way to evaluate this is by determining the R/S ratio. Define the R/S ratio. 1.2Both rhizospheric and root-free soils were collected from five (5) plants before (BT) and after (AT) treatment. Using the microbial biomass that appear in Table 1, the R/S ratios before (BT) and after (AT) can be determined. Use these values to determine the respective R/S ratios. Kindly show all workings.
