Iowa crop and livestock farmers, as top producers of corn, soybeans, pork, eggs, and other agricultural products – are in an advantageous position economically and environmentally. Not only do livestock producers enjoy the benefits of locally grown crops for the feed that they need, but crop producers also enjoy the benefits of using manure as a nutrient source. To help producers make the most of Iowa’s available manure nutrient resources, Iowa State University Extension recently developed an updated publication, Using Manure Nutrients for Crop Production - PMR 1003.
