主 题：Atmosphere Greenhouse gases Conservation tillage Sustainable crop yield
摘 要：There is an urgent need to match food production with increasing world population through identification of sustainable land management ***,the struggle to achieve food security should be carried out keeping in mind the soil where the crops are grown and the environment in which the living things *** agriculture(CA),practising agriculture in such a way so as to cause minimum damage to the environment,is being advocated at a large scale *** tillage,the most important aspect of CA,is thought to take care of the soil health,plant growth and the *** paper aims to review the work done on conservation tillage in different agro-ecological regions so as to understand its impact from the perspectives of the soil,the crop and the *** reports have identified several benefits of conservation tillage over conventional tillage(CT)with respect to soil physical,chemical and biological properties as well as crop *** less than 25%of the greenhouse gas effluxes to the atmosphere are attributed to *** of climate change mitigation and adaptation found zero tillage(ZT)to be the most environmental friendly among different tillage ***,conservation tillage involving ZT and minimum tillage which has potential to break the surface compact zone in soil with reduced soil disturbance offers to lead to a better soil environment and crop yield with minimal impact on the environment.&2015 International Research and Training Center on Erosion and Sedimentation and China Water and Power *** and Hosting by Elsevier *** is an open access article under the CC BY-NC-ND license(http://***/licenses/by-nc-nd/4.0/).
