摘要

Meta-analysis-based publications have gained considerable importance in the recent decade. Similar studies of techniques and management practices convey the findings more emphatically. However, limited meta-analysis studies have been published to date on the impacts of conservation agriculture (CA) on soil biological parameters in the Indian subcontinent. To address this gap, we collected data from 35 publications and 412 paired observations on CA vs. conventional tillage (CT) during the period from 2000 to 2020, based on soil biological parameters. We analyzed the data using the software Meta-Win 2.1 at p < 0.05 significance level. The result showed higher microbial biomass (MB) and enzyme activities under CA over CT practice. The MB carbon (MBC), MB nitrogen (MBN), dehydrogenase, fluorescein diacetate hydrolysis, β-Glucosidase activity, and Urease increased by 14, 19, 25, 18, 26, and 19%, respectively, under CA than CT. Following CA, MB was higher in all geographical regions and soil textural groups of India than CT practices. The highest MBC and MBN levels in CA were found in the northeast and northwest regions, compared to the western and southern parts of India. Other factors, such as rainfall, soil depth and total nitrogen, also significantly influenced MB and soil organic carbon concentration in the soil. The findings of this study illustrate that CA promotes higher MB and enzymatic activities than CT in the Indian subcontinent soils.
