Section 327IAC6.1-2-8. "Cation exchange capacity" defined

   "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*.

  *The summation method for distinctly acid soils and the sodium acetate method for neutral, calcareous, or saline soils can be found in "Methods of Soil Analysis, Agronomy Monograph No. 9.", C.A. Black, ed., pp. 149-157, 1982, available from American Society of Agronomy, Soil Science of America, Inc., 677 South Segoe Road, Madison, Wisconsin 53711.
