Dairy producers have many duties to carry out in their dairy operations, one of which is storing, handling and applying manure. Manure handling can be a significant cost on most dairies even when considering the value of the nutrients in the manure. Seldom do producers consider their costs of handling and applying manure on a per hundredweight (cwt) of milk sold basis like they do with many of their other costs.
In Iowa, the annual grain production requires replenishment of the fertility of the soil. Deep soils and high yields are a perfect solution for recovering value from manure. Technologies for better application and more efﬁcient handling are applied throughout Iowa. Dairy manure values, according to Iowa State University specialists, are such that a corn producer can easily have more than enough fertility brought onto his farm to fully fertilize the following year’s crop and more.

The Iowa State University Extension and Outreach Dairy Team will host its annual Dairy Discussions Seminar on Tuesday, December 1, from 10 a.m. to noon. The program is sponsored this year by EcoEngineers, a renewable energy consulting and auditing firm headquartered in Des Moines, Iowa, and the Iowa Economic Development Authority (IEDA). The program will be virtual due to health concerns with the COVID-19 pandemic.
This year’s focus is on manure management systems, opportunities in renewable natural gas (RNG) to maximize profitability in the dairy industry, and the benefits of co-locating a dairy near a biofuel facility in the Midwest. The presentations will include a case study for an Iowa dairy and the minimum project size to make RNG project economics work.
