Effects of vermicompost on soil microbiological properties in lettuce rhizosphere: An environmentally friendly approach for sustainable green future
Environ Res. 2023 Nov 28:117737. doi: 10.1016/j.envres.2023.117737. Online ahead of print.ABSTRACTThe aim of this study is to investigate the effects of vermicompost on the biological and microbial properties of lettuce rhizosphere in an agricultural field in Samsun, Turkey. The experiment was conducted in a completely randomised design (CRD) and included four vermicompost dosages (0%, 1%, 2%, and 4%) and two application methods (with and without plants). Batavia lettuce was selected as the test plant due to its sensitivity to environmental conditions and nutrient deficiencies. The study evaluated the changes in organic matter (OM), pH, electrical conductivity (EC), carbon dioxide (CO2), dehydrogenase activity (DHA), microbial biomass carbon (MBC), and catalase activity (CA) in the rhizosphere of lettuce plants treated with different vermicompost levels (0%, 1%, 2%, and 4%). The findings showed that vermicompost application significantly increased chlorophyll content in lettuce plants, with the highest content observed in plants treated with V1 compared to the control. Different vermicompost concentrations also influenced chlorophyll b and total chlorophyll levels, with positive effects observed at lower concentrations than the control. Plant height and fresh weight were highest in plants treated with V2, indicating the positive impact of vermicompost on plant growth. Additionally, vermicompost application increased plant dry weight and improved soil properties such as pH, or...
