Setback Checklist - Identify Prohibition Areas

Check List for Setback and Application Restrictions

Prohibition Areas

    ; Concentrated flow channels with established vegetative cover

; Vegetative buffer areas

; Non-farmed wetlands

; Land where established vegetation is not harvested

; Area within 50 ft of a well

; Within 200’ upslope of direct conduits to groundwater, unless incorporated within

    3 days

     Wells

     Sinkholes

     Fractured bedrock at the surface

     Gravel/sand pits

FROZEN SOILS, DO NOT apply nutrients:

    ; Within the surface water quality management (SWQMA) areas - 1000’ of lakes,

    300’ of perennial streams (refer to map on next page)

; On slopes >9% (can apply manure on slopes up to12% where cropland is contoured

    or contour strip cropped)

; apply manure P2O5 so as not to exceed current year’s crop removal and limit liquid

    manure applications to 7,000 gallons/acre

Limit available N applications on:

    ; high permeability soils

    ; soils with less than 20 inches to bedrock

    ; soils with less than 12 inches to apparent groundwater:

50ºF or less in the Fall:

     Limit available manure N to 120 lbs/A

     Greater than 50ºF in the Fall (pick one):

     Limit available manure N to 120 lbs./A + nitrification inhibitor

     Limit manure applications to crop N need or 120 lbs. ac + on perennial or fall

    seeded crops

     Limit available manure N to 90 lbs. / ac + apply after Sept. 15th

Check List for Setback and Application Restrictions

Non-frozen soils within a SWQMA:

    ; No liquid manure (<12% solids) applications on saturated soils!

Use one or more of the following practices:

    1. Establish & maintain permanent vegetative buffers

    2. Maintain 30% crop cover on soil surface after application

    3. Incorporate nutrients within 72 hours

    4. Cover crop established promptly following application

    Maximum Rates of Unincorporated Liquid Manure Applied on Non-frozen soils within a SWQMA:

     Manure Application

    Surface Rate, gallons/acre Allowable Soil Moisture Description for

    Texture Class Applications

    <30%* > 30%*

    Fine 3,000 5,000 Easily ribbons out between fingers, has a

    slick feel

    Medium 5,000 7,500 Forms a ball, is very pliable, slicks readily

    with clay

    Coarse 7,000 10,000 Forms a weak ball, breaks easily
