Short-Term Effects of Crude Botanical Extracts and Rhizosphere Soils on Soil Respiration and β-Glucosidase Activity
Plant-derived compounds may modify microbial carbon turnover, but their effects on soil respiration and enzyme activity are poorly documented. This laboratory study compared crude ethanolic extracts and rhizosphere soils of garlic, ginger, turmeric, moringa and aloe vera with untreated soil during a 5-week incubation (n = 3). Extracts reduced basal respiration and cumulative CO2-C relative to the…
