Feeding the Soil: A Farmer’s Take on the Growers Program | Growers Mineral Podcast

In this episode, Jim Halbeisen sits down with central Iowa farmer David Armstrong, who’s been using the Growers Mineral program for over 30 years. David shares why he believes feeding the soil biology is the key to healthier crops, better cattle performance, and long-term sustainability.

Hear firsthand how he uses 2x2 and in-furrow application, why available calcium matters more than total calcium, and what happened when he applied 50 tons of gypsum per acre—just to prove a point. David’s approach challenges the conventional model and puts results first, from tissue quality to animal health to shelf life in produce.

If you’re looking for a program that’s built on observation, results, and true soil function—this is the conversation for you.
