The Soil Conditioning Index (SCI) is a tool for organic matter prediction used by the Natural Resour ces Conser vation Service (NRCS) that utilizes the effects of climate, tillage, and er osion on organic matter decomposition at various geographic locations. The three components of the SCI include (1) the amount of organic material returned to the soil, (2) the effects of tillage and field operations on soil organic matter decomposition, and (3) the effect of pr edicted erosion associated with the man agement system. The SCI gives an overall rating based on these components. The original intent of this pr edic tive tool assumed that a negative rating would indicate soil organic matter degradation, a zer o would mean status quo, and a positive number would mean an increase in soil organic matter . The objectives of this study were to generate SCI ratings for plots in long-term carbon studies in several r
