Book excerpt: Conservation tillage systems and rotations with corn (Zea mays (L.) increases surface residue and make popular choices for erosion control in soybean (Glycine max (L.) production. Tillage and system (rotation) affect levels of residue input which in turn affect the response of the soil and plants. Few studies have looked at the long term (23 years) effects of management practices on soil and soybean physiology. The objectives of this study were to (i) determine the effects of surface residue on soil temperature throughout the growing season, (ii) determine the effect of amount of residue on SOC, and (iii) determine the physiological response of soybean to residue, system and tillage treatments. Rotation and NT increased surface residue and soil organic carbon (SOC) for the top 0-5 cm of soil in both years of data collection. Continuous soybean and tillage increased maximum soil temperatures but did not affect minimum temperatures over the course of the study. The differences in plant height and canopy coverage were limited and not directly related to changes in soil temperatures. Long term decisions in tillage and system have a direct effect on soil response but the physiological response of soybean isn’t fully understood.
