Introduction • Poultry manure provides nutrients for crops and

feedstock for generating renewable energy.

• Poultry manure storage and application should be carefully managed to control water and air pollution.

• Understanding the availability, transportation, and application of poultry manure can benefit Indiana agriculture.

• However, there is a lack of data and reliable methods to estimate poultry manure production.

Objectives • Develop new poultry manure calculation method.

–Collect Indiana poultry inventory data

–Select reliable poultry manure production rates

• Calculate poultry manure production, assess availability, and

determine geographical distribution.

Preliminary Results

Conclusions • Combining different sources of data can help

improve manure production calculation.

• New information and methods are needed to

calculate manure production from non-CFO/CAFO

farms.

NEXT STEPS:

• Survey poultry manure haulers and crop producers.

• Examine crop producers’ interests and willingness

to pay for litter.
