MAPS for Nutrient Management Plans
  • By Julia W. Gaskin, UGA - Bio Ag Engineering
    Vernon Jones, NRCS (retired)

Presented by Thomas Bass, UGA - Bio and Ag
Engineering May 10, 2005 Macon, GA

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

Soils Map - Joe Blow Farm
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

9
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.
