Animal production in the USA is valued at more
than $100 billion and has consolidated significantly
during the last 20 years, with a larger
number of animals being produced on an
increasingly smaller land base (Kellogg et al.,
2000). Manure generated from animal production
is currently estimated to exceed 335 million t
of dry matter per year in the USA, while global
manure production is estimated at —13 billion t
of dry matter per year (Mullins et al., 2005).
Manures contain significant amounts of phosphorus,
with values between 6.7 and 29.1 g P/kg on
a dry weight basis reported for several species
of animals (Barnett, 1994). This phosphorus
includes inorganic and organic forms, with the
latter constituting between 10°/a and 80% of the
total (Peperzak et al., 1959; Gerritse and Zugec,
1977). Inositol phosphates are one of the primary
organic phosphorus species found in manures,
with myo-Inositol hexakisphosphate typically
being the most abundant (Peperzak el al., 1959;
Barnett, 1994; Turner and Leytem, 2004).
