Consider a soil with bulk density of 1.34 g/cm3 soil. Sampling the top 7 inches of this soil and measuring the cation exchange capacity (using the ammonium acetate method) results in the following cations exchanged by NH4: 8.9 cmol Ca2*/kg soil, 3.7 cmol Mg2+/kg soil, 3.8 cmol K*/kg soil, and 3.8 cmol Al3+/kg soil. How much Ca2+ is present on the CEC in the top 7 inches of each acre of this soil (in pounds Ca/AFS)? Your Answer: Answer units
