Calculate Liming Requirements. You have a soil sample with a CECof 10 meq / 100 g soil, a pH of 4.8 and a BS of 37%. You would liketo raise this soil to a pH of 6.5, so you need to raise the BS to65%. You also have a Mg deficiency. Assume 93% purity of yourliming agent. During screening of a 100g sample, you had 1.5 g onthe 8-mesh screen, and 13.4 g on the 60-mesh screen. Choose theappropriate liming agent and calculate CCE, ECCE, and the tons oflime you need to apply to your 100 acre field.
