Poultry Litter nutrient source

The poultry industry in the US produces:

• 580,000 Mg of Nitrogen (480,000 Mg in excess) and,

• 280,000 Mg of Phosphorus (250,000 Mg in excess)(Gollehon et al., 2001, Agriculture Information Bulletin)

Poultry litter stabilization, pathogen and odor reduction

Ash (complete combustion)

• high concentration of minerals (P, K, Ca, Mg,.• Loss of nitrogen (N)

Biochar (pyrolysis, carbonization)

• concentration of minerals (P, K, Ca, Mg,.• 70% of N lost (400 °C depending on temp.)

Compost (composting)

• Concentration of minerals (P, K, Ca, Mg,.• Loss of nitrogen (NH3 volatilization, 70 –88%, Ogunwande et al., 2008)

Carbonized Poultry litter consequences for N availability?

Knicker and Skjemstad (2000) “Alterations in chemical structure have long-term consequences for N availability” “Black nitrogen” Knicker (2007)

Chan et al. 2008 “The yield increases were largely due to the ability of poultry litter char to provide N”

Tagoe et al. 2008 “Less N derived from poultry manure if carbonized (C = 12%) but more total uptake”
