Abstract
As environmental regulations
continue to tighten and shift from
nitrogen to phosphorus-based
application standards for manure,
phosphorus removal will become
increasingly important for any state
considering a livestock growth
initiative. A framework was
developed that can determine a
state’s phosphorus removal capacity
based upon production of livestock
and crops and varying phosphorus
removal standards. The state level
results indicate that Indiana, along
with Arizona, Illinois, Iowa, Kansas,
and Texas, are well positioned to
undertake a livestock growth
initiative given that each state has
excess phosphorous removal
capacity.
