AREs only apply to the upper one foot of soil or soil/gravel mixture and are used as the SCO for the upper one foot of soil or soil/gravel mixture if the ARE is greater than the SCO value calculated using the Equation in Section 259.350(a) of this Part and less than the RSDL value. The application rate equivalents can be determined using the equation below: Where: ARE s = application rate equivalent (mg/kg) Application rate = current label application rate (lb/acre) for coarse-textured, low organic matter content soils
