Grassland Revegetation for Mine Reclamation in Southeast Arizona

Summary: 

Mine land reclamation techniques were tested in arid Southeast Arizona for their potential to enhance reclamation success on two sites at different elevations (1400-­ and 1650-­meters above sea level) on two sandy loam soils (Arkose and Gila Conglomerate). Seedbed preparation (smooth or rough surface) and straw mulch treatments (surface mulch, mulch incorporated into the soil, or no mulch) were tested for their potential to establish vegetation and prevent erosion. Gila soil retained 12.9% more soil moisture than the Arkose soil and was preferred by the seed mix (Gila: 64.4 plants m‐2; Arkose: 23.2 plants m‐2). A rough surface with surface mulch was recommended. Gila soil was more susceptible to erosion likely because it contained smaller soil particles. Rock cover was associated with significantly (P=0.0138) reduced rate of soil movement (0.1588 cm soil loss or accumulation per 1 percent rock cover). Proper soil management can be critical for reclamation success.
