10. A soil analysis was performed to determine the cation exchange capacity based on exchangeable Na, K, Al, and Mg, and the results were:
4 cmol Na/kg 4 cmol K/kg 3 cmol Al/kg 2cmol Mg/kg
Calculate the Cation Exchange Capacity.
11. A similar analysis was performed for the following cations. However, this time the results were reported as mg of the cation per kg of soil as follows:
Na = 500 mg/kg K = 2000 mg/kg Ca = 1000 mg/kg Mg = 1500 mg/kg
Calculate the CEC

A soil analysis was done for the exchangeable cations in the soil and the results were as follows: Ca = 7 cmol/kg Mg = 4 cmol/kg K = 585 mg/kg (atomic wt. Potassium is 39 g/mol) Na = 1 cmol/kg Al= 135 mg/kg (atomic wt. Aluminum is 27 g/mol) H= 3 cmol/kg Calculate the CEC of this soil –do not forget the units and please show example calculations

Please Answer: CALCULATION QUESTION 1 (A) Calculate the number of cmol of Al3+ cations needed to replace 10 cmolc of Ca2+ by cation exchange in a soil. (B) How many grams of Al3+ does this correspond to? (you’ll need the atomic weight of Al, which is 27 g/mol, to calculate this) CALCULATION QUESTION 2 A soil sample (500 g) contains the following amounts of exchangeable cations: Ca2+= 9 cmolc , Mg2+= 3 cmolc , K+= 1 cmolc , Al3+= 3...

Soil testing laboratories usually estimate cation-exchange capacity (CEC) as the sum of Ca2", Mg, and K displaced during extractions with neutral, 1 N ammonium acetate (NH 0Ac), which are performed primarily to test for available K. The following data were thereby obtained for three contrasting soils, but have been reported as pounds per acre for each of the three elements, assuming the conventional weight of 2 million pounds for an acre of soil 6 inches deep. Soil A 4004 381...
