Abstract

Several large poultry confinement sites have been established in north central Iowa during the past ten years. Many farmers are applying the chicken manure during the fall and winter months as a fertilizer source. Although not desirable, applications have been made to frozen soils and snow covered fields. In 2000 an experiment was started to evaluate yield response to chicken litter applied to snow-covered fields. The objective of the experiment was to document yield responses to applications made during the winter and spring at two different rates. The focus was on response to nitrogen from manure rather than phosphorus or potassium.
