Objective

• Prepare maps needed for CNMP
• Location map (optional)
• Soils map (optional)
• Farm map (required)

3
Location Map

• Computer road maps
• Photocopy road map
• Add arrow and dot to mark farm location
• Add North arrow
• Add title - Location Map at bottom
• Scale

5
Farm Map

• Information required
• Farm property lines
• Land use - cropland, pasture, etc
• Field boundaries
• Unique field identifiers
• Surface water features
• Arrows showing water flow direction
• Buffers or setbacks

6
Farm Map

• Information required (cont.)
• Well locations
• Residences or public gathering places
• Road names
• North arrow
• Date prepared
• Legend
• Bar scale
• Probably off of farm property

7
Information Sources

• FSA maps
• Aerial photos
• Internet -
• http//terraserver.microsoft.com - free
• http//www.gis.state.ga.us - fee based
• NRCS Toolkit

Creating a Base Map

• Obtain FSA map
• Put a 1-inch
  bar scale on map
  before photocopy

Creating a Base Map
11
Calculating Spreadable Acreage

• Mark buffers on map
• Use dot grid, planimeter, etc to measure
• Subtract from total acres in field
• NRCS Toolkit

12
Spreadable Acres

• Surface flow directions
• Concentrated flow areas
• Filter strips
• Frequently flooded soils
• Riparian forested buffers

• Setbacks
• Property line
• Houses or public areas
• Well
• Road
• Phosphorus Index
• Irrigation patterns

Summary

• Farm map is required
• Has to be scaled to calculate spreadable acres
• NRCS Toolkit provide maps
• Base map from FSA or internet
• preparer adds required information

23
Buffer Review Manure App.

• Required (GA) - New large operations only (new
  regs may extend coverage of 35/100 ft rule to
  additional operations, 2003)
• 35 ft vegetated or 100 ft from surface water,
  wet areas and ditches
• 100 ft from wells
• Recommended
• 35 ft from ponds, sinkholes and wetlands
• 25 ft from property lines
• 50 ft from public road (situational)
• See FarmASyst 1152-3 Improving Drinking Water
  for the Rural Resident for additional well
  setback recommendations.
