An Alabama minesoil classification system was developed based on soil texture, soil color value and soil pH. Only five different soil classes were found in this study. However, the classification scheme allows for the inclusion of any minesoil that occurs on the basis of its texture, color value and pH. Limestone and fertilizer recommendations are given for soils of the five minesoil classes. Research evidence showed that the limestone recommendations will maintain a pH favorable to plant growth and surface soil water quality for a period of at least one year. The scope of this project did not allow determination of water quality where the water had leached downward through the minesoil. The recommended fertilizer rates should supersede those of a soil testing laboratory if the laboratory recommends lesser amounts of fertilizer. Also, the recommended rates can be used if soil test recommendations are unavailable.
