327 IAC 6.1-6-3 Agricultural lime substitute application

Sec. 3. Agricultural lime substitute must be evenly applied at rates based on the adjusted lime rate as determined by Equation 4 as follows: Equation 4: Adjusted Lime Rate = RALR × FF × NF × DF Where: RALR = Recommended agricultural lime rate derived from the soil analysis report for the application site. FF = Fineness factor. NF = Neutralizing factor. DF = Depth factor.
