Application Date

Date you want to apply: You must do this evaluation no more than 24 hours prior to application.

Field Name or Unit

Do a separate evaluation for each field or management unit. A "management unit" is a group of fields with similar soil, crop type, and management conditions.

24 hour Precipitation ( inches )

Risk Rating: N/A

72 hour Precipitation ( inches )

Risk Rating: N/A

Soil Type

Enter the general soil type you want to apply to. If you dont know your soil type, make your selection under "Don't know". Soil type can be found on your farm plan map.

Sandy/Gravelly (Course Textured Soil - A)

Silt (Medium Textured Soil - B)

Clay (Fine Textured Soil – C/D)

Peat/Muck (Organic Soil)

Don't know

Soil Moisture

Enter moisture value in %. Click on the link for guidance on how to determine soil moisture here

90-100% (If your boots squish in the field, you are at saturation)

80-90% (In this range you would not comforatably drive a tractor into the field and are worried about potential soil compaction due to field wetness)

60-80% (In this range you could comfortably drive a tractor out into the field without worrying about ruts or field compaction)

< 60% (In this range your soil is firm and starting to dry out)

Risk Rating: N/A

Water Table Depth ( inches )

Water table can be determined by nearby ditches, or by digging a hole in your field. For more on how to determine water table depth, click HERE.

Risk Rating: N/A

Forage Density ( % )

Click link for guidance on how to determine forage density here

90-100%

70-90%

50-70%

< 50%

Other: Annual/Fallow/Row Crop Field (eg, new seeding, corn, berry, bare soil, etc.)

Risk Rating: N/A

Forage Height ( inches )

Forage/cover height is the average height of forage or cover in your field. If you are not evalauting a forage field, select "Not forage crop".

Risk Rating: N/A

Field Surface Condition

Check all that apply to your current field conditions

Ponding

Flooding current or potential in 15 days

Frozen ( more than 1 inch ) or snow covered

Tiles present in field

None of the above

Risk Rating: N/A

Manure Application Equipment

Check equipment/method of application

Below surface applicator (eg, injector, incorportaion within 24 hours)

Surface application (eg, splash plate, tank, aerator)

Irrigation sprinkler (eg, Big Gun)

Grazing

Solid Manure Application

Risk Rating: N/A

Waterbody or Critical Area

Do you have a waterbody (i.e., ditch, stream, river, etc.) or identified critcal area (i.e., swale, wetland, etc) adjacent to your field?

Yes (answer next two questions)

No (click submit)

Manure Setback Distance

Manure setbacks must be a minimum of 10 feet from May 1 to August 31 (40 for Big Gun use). 40 feet from September 1 to May. and 80 feet from October 1 to February 28. For more information on seasonal manure application setback distance, click here

Buffer

Do you have a dedicated vegitative buffer next to the water body? [If you are applying to a grass field, your grass acts as a “vegetative buffer” as long as it is dense and greater than three inches in height.]

Yes, it is less than 35 feet

Yes, it is greater than 35 feet
