Every farm that generates or utilizes manure needs a plan. Who needs what plan?

• CAFO – Act 38 plan• CAO – Act 38 plan• Importer from CAFO or CAO – Act 38 Nutrient

Balance Sheet

• AO and their importers – – DEP Manure Mgmt Plan or– DEP Manure Mgmt Plan Nutrient Balance Sheet or– Act 38 Plan or– Other plan approved by DEP

Winter Application Worksheet (p.5)

Winter ManureApplication= High Risk


Winter Application Worksheet



Winter Application• High & Dry• Ground cover• Prioritize application to locations that will

minimize risk• Low app rates over more acres• Skip strips when applying on snow to provide a

alternating breaks between manured and non-manured areas

• Skip and give wide breaks in subtle low areas and preferential water flow paths

Diminishing Returns – applying over more acres limits risk and makes economic sense

• General Characteristics of Response Curves• Diminishing Returns Curve – not linear!

Using the MMM Manure Application Rate Tables

Step 1: Find the table in the back of the MMM (Appendix 1) for:

1. Rate basis N or P-N only if soil test

>200ppm

2. Type of manure

Step 2: Find the crop in the table

Example Table (p.7)

• No more than 9000 gal/A of liquid manure can be applied in a single application.

• Spilt higher rates into multiple applications.

1. Find the yield at the top2. Find the application method in the left column3. Read the rate from the table

Farmer’s normal rate = 9000 gal/A.

This is less than the table rate of 16,000 gal/A.

Therefore the normal rate is OK.

Solid Manure StoragesSolid

Manure Storages

No specific monthly documentation is required for solid manure storage facilities


Manure Stockingpiling and Stacking Areas

• Requirements for manure stacking at the farmstead– Manure stacking in the farmstead must use an improved stacking pad or covered area

– NRCS or conservation district specialists can provide assistance


Manure Stockpiling and Stacking Areas

Unimproved & Unacceptable

Farmstead Manure Stacking


Manure Stockingpiling and Field Stacking Areas• Requirements for temporary stacking in non-farmstead areas

such as crop fields: – Keep at least 100 feet from sensitive areas

• Streams, lakes, ponds, open sinkholes, drinking water wells– Cannot be placed within an area of concentrated water flow

• Swale, ditch or waterway– Use properly constructed improved stacking pads whenever possible– In-field stacking areas should not be in the same location each year– High & Dry - Place at the top of a hill, where possible

• Divert upslope water away from stacking areas– Place on areas with less than 8% slope.– Manure must be dry enough to allow for stacking at least 4 feet in

height– Limit volume to amount that can be spread on fields nearby to the

stack– Stack must be covered if it will be in place longer than 120 days
