Dan Andersen discusses whether irrigation has a role in the future of Iowa agriculture and what it would look like. 

Dan Andersen discusses managing nitrogen and manure application in response to potential weather impacts caused by an El Ninõ event. 

In this episode, Dan explores the yield goal method, MRTN, and N-FACT, and how recommendations influence manure application across Iowa. He also looks at recent spatial mapping and its impact on manure management practices.

In this episode, Dan Andersen discusses the science and management of manure crusts. He explores the benefits and challenges of crusts, which can reduce odor, ammonia emissions, and methane production, but can also cause pumping difficulties and attract flies and rodents. 

In this episode, Dan Andersen and Laura Pepple, director of supply chain and logistics at Puck Enterprises Inc., explore how modern dragline manure systems efficiently transport manure. They discuss key design factors like application rate, equipment, and field distance, while emphasizing proper planning. 

In this episode, Dan Andersen is joined by Mitch Baum to discuss the late-spring nitrate test and its role in nitrogen management.

Dan Andersen discusses the management of biogas, particularly methane from manure, and its impacts on greenhouse gas emissions. 

Dan Andersen is joined by Cain Bynum to discuss the spatial analysis of manure management in Iowa using GIS to align manure nutrients with crop demand.

This month on Talkin' Crap, Dan Andersen sits down with Christina Murphy, General Manager of West Des Moines Water Works, to discuss how urban drinking water is treated, monitored, and delivered safely to the public.

They also explore the shared challenges faced by both agriculture and water utilities, from nutrient management to water quality pressures, and discuss collaborative steps to improve water quality. 

In this episode, Dan Andersen discusses the challenges and uncertainties in manure management related to the variability in manure nitrogen content.
