Goal: This Verification of Depth to Bedrock (formerly known as Verification of Land Features) Standard Team will create a new technical standard for use in verifying and documenting land features when a landowner wishes to contest the current depth to bedrock categorization of cropland specifically for the purposes of applying manure as a crop nutrient. Currently available depth to bedrock information varies by county and consists of a combination of information from multiple sources. The standard will establish valid methods and technologies for taking measurements, the appropriate scale for identifying features, and the qualifications of persons who may perform verification. The standard will support implementation of s. NR 151.075 in designated areas where the bedrock consists of Silurian dolomite with a depth to bedrock of 20 feet or less.  It may also be appropriate for use in other areas of the state where depth to bedrock is a resource concern.

To clarify the scope and limits of this new standard, this document outlines which categories and topics are addressed under Technical Standard 01 Verification of Depth to Bedrock versus program implementation decisions to be determined by DATCP or DNR through rulemaking.

This team will examine existing research, consider new technologies, propose criteria, and consider input from expert and public review.
