Relative Neutralizing Value (Rnv)

The neutralizing potential of all agricultural liming materials shall be indicated by the Relative Neutralizing Value (RNV). The RNV shall be determined by multiplying the percent of lime particles in each size range (specified by U.S. Standard Sieve Sizes) by the respective Efficiency Factor yielding the particle size efficiency factor. The summation of the particle size efficiency factors is then multiplied by the Calcium Carbonate Equivalent (CCE) to result in the Relative Neutralizing Value. The minimum RNV of liming material allowed to be sold, offered for sale or distributed shall be the value of sixty-five (65).
