METHODS FOR AMELIORATING/NEUTRALIZING ACIDITY IN SOILS

摘要

There are provided methods for the rapid amelioration/neutralization of acidity in acidic or sodic soil or in acid mine drainage areas, by the application of a volume of a calcium bicarbonate [Ca(HCO)3)2] solution to the surface of subsurface of the soil or to the acid mine drainage areas, optionally followed by the application of a leaching volume of water, the calcium bicarbonate solution penetrating the soil or subsoil or the acid mine drainage areas to a depth of at least about 2cm below the surface of said soil or acid mine drainage areas.
