2. Calculate Effective Calcium Carbonate Equivalent (quality score) of the lime source with the properties listed below. a. 85% CaCO3 b. 57% of the lime passes through a 10-mesh sieve C. 45% of the lime passes through a 60-mesh sieve d. Fineness factors i. Lime >10-mesh size = 0% effective ii. Lime <10 mesh and <60 mesh mesh size = 40% effective iii. Lime <60 mesh mesh size = 100% effective 3. How much of the lime source in question #2 is needed to satisfy a lime recommendation of 50C lb/acre of lime having 100% ECCE (100% pure CaCO3 with all particles < 60-mesh diameter).
