Question

Calculate Liming Requirements. You have a soil sample with a CEC of 10 meq / 100 g soil, a pH of 4.8 and a BS of 37%. You would like to raise this soil to a pH of 6.5, so you need to raise the BS to 65%. You also have a Mg deficiency. Assume 93% purity of your liming agent. During screening of a 100g sample, you had 1.5 g on the 8-mesh screen, and 13.4 g on the 60-mesh screen. Choose the appropriate liming agent and calculate CCE, ECCE, and the tons of lime you need to apply to your 100 acre field.
