Abstract

Iowa is the number one egg producing state in the nation, with nearly 16 billion eggs produced in 2017 (USDA-NASS, 2018), and an estimated 2 million tons of fresh manure generated from these facilities annually. Although poultry manure can be a valuable resource for crop fertilization and soil amendment, these benefits need to be weighed against potential negative environmental impacts. Poultry manure applied to meet crop nitrogen requirements may result in other nutrients, such as phosphorus, applied at rates that do not match crop needs, as well as introducing potential pathogens that may be associated with manure application. The transport and movement of excess nutrients and other contaminants from fields may be exacerbated by tile drainage.
