In this episode, Dan Andersen looks beyond N and P and focuses on how soil properties and equipment choices impact the volume of manure that can be applied.
Liquid Slurry Manure Movement in Soil
Anaerobic Digester Performance
Dan Andersen begins the episode with manure gases and road safety reminders for fall manure application. Later in the episode, Luke Soko, a graduate student at Iowa State University, joins Dan to discuss his research, which focuses on anaerobic digester performance between covered lagoons and heated digesters.

Manure Systems and Carbon Footprints
Dan Andersen delves into carbon neutrality in livestock production, and the impact manure emissions have on a carbon-neutral system. He also looks at current practices, like anaerobic digestion, that are already being used to reduce methane emissions, as well as practices being considered for the future.

Manure and Spill Response in Iowa
In this episode, Dan Andersen discusses manure spills, including common causes of spills, how spills are contained, and use of technology to help prevent equipment failure. Dan also looks at the causes and timing of fish kills in Iowa, as well as the downward trend of livestock and manure-related fish kills. Find show materials here.
Circularity and Systems Thinking in Manure Management
Our first podcast examines the science, technology, and best management practices surrounding manure management. Dan Andersen, Rachel Kennedy, and Melissa McEnany discuss circularity and systems thinking in livestock and manure management. Find show materials here.
