Abstract
The increasing cost of commercial fertilizers and the avail
ability of animal waste
that has high nutrient content have led to producers utilizing animal waste such as poultry
litter in their fertility programs. This increased use has raised concerns as to what are the
optimum rates to apply to meet crop needs and
how will long term use at high rates of
litter effect soil test levels of nutrients such as phosphorus and potassium. The objective
of this study was to address these concerns. This study has been ongoing since 1998 with
treatments of zero to seven tons …

The production of perennial cellulosic feedstocks for bioenergy presents the potential to diversify regional economies and the national energy supply, while also serving as climate ‘regulators’ due to a number of biogeochemical and biogeophysical differences relative to row crops. Numerous observational and model-based approaches have investigated biogeochemical trade-offs, such as increased carbon sequestration and increased water use, associated with growing cellulosic feedstocks. A less understood aspect is the biogeophysical changes associated with the difference in albedo (a), which could alter the local energy balance and cause local to regional cooling several times larger than that associated with offsetting carbon. Here, …
