Technical Abstract: This college-level textbook is designed to help students and researchers understand the complexity of how to manage soil organic matter in a diversity of agroecosystems. This chapter describes the current state of knowledge on how tillage and residue management affect soil organic matter. Types of tillage and residue management are reviewed. Available literature is summarized with regards to the effects of tillage on (1) depth and aggregate-size distribution of soil organic matter, (2) total organic carbon and nitrogen, (3) the various fractions of organic matter, including particulate, density, and biologically active, and (4) the interactions with cropping intensity, soil texture, and climatic region. Major emphasis of the chapter is on the comparison of conservation tillage with more conventional inversion tillage systems.
