This document announces a three-part webcast series from November 2013 to January 2014 on capturing valuable nutrients from manure. It discusses the top five reasons to capture nutrients from manure, including that less than half of consumed nutrients are captured in final products, commercial fertilizers have become expensive, and there is evidence of nutrient-impaired water. It also addresses balancing nutrient inputs and outputs on farms to prevent excess nutrients from leaving farms and entering water sources. The series will feature presentations on phosphorus capture technologies and balancing nutrients on dairy and swine operations.
