ABSTRACT The efficacy of limestone sand and pelletized lime for remediation of soil acidity was compared in order to determine if limestone sand was a more cost-effective alternative to pelletized lime. Between fall of 2002 and spring 2003, two forested sites in Pennsylvania were clear cut and fenced. Pelletized lime and limestone sand were applied to separate 400-m 2 plots within the sites at rates of 2170 kg·ha -1 and 4335 kg·ha -1 , respectively. Two additional 400-m 2 plots were used as controls. A paired before-after control-impact study design was used...
