"Cation exchange capacity" means the sum of exchangeable cations a soil can absorb expressed in milliequivalents per one hundred (100) grams of soil as determined by sampling the soil to the depth of cultivation, sludge waste product placement, or wastewater placement, whichever is greater, and analyzing by the summation method for distinctly acid soils* or the sodium acetate method for neutral, calcareous, or saline soils*.
