This article examines the impact of no till systems in a 12 year trial in the central highlands of Mexico, specifically focusing on effects on microbial biomass and catabolic diversity in rainfed smallholder agricultural systems. A significant finding of the study is that zero till without residue retention is an unsustainable production practice.
