You are a golf course superintendent that is seeding a renovated fairway. The soil of the fairway has a clay loam textured soil with a pH of 6.0. A soil test shows that the CEC + 40 meq/100 g soil and the % BS (Base Saturation) is 60 %. (a) Calculate the amount of CaCO₃ (in tons per acre furrow slice or 6depth) required to bring the pH to 6.8 and to obtain % BS of 90 %.

In addition to the availability of CaCO₃ (m.w. = 100) as a liming material, you also have access to an adequate supply of CaO (m.w. = 56) as a liming material. (b) Calculate the CCE of the CaO, and (c) how much CaO would you use instead of CaCO₃ to lime the soil?
