Jason Cavadini is an agronomist and the assistant superintendent of the University of Wisconsin Marshfield Agricultural Research Station.

He obtained a Bachelor’s Degree in Soil Science from UW-River Falls, and a Master’s in Agronomy from Purdue University where he focused on the use of cover crops as a soil conservation practice. At the Marshfield Agricultural Research Station, Jason has been dedicated to integrating the practices of no-till and cover crops into Central Wisconsin.

On a farm where biodiversity, environmental concerns and sustainability are of equal importance, a herd of 58 New Zealand Friesian milking cows graze contentedly among green blades of orchard grass and white blossoms of clover. Cows, along with unconfined laying hens and a few pastured pigs, have grazed for more than 20 years on Heidel Dairy, a 294-acre farm operated by David and Angelita Heidel and their daughter and son-in-law, Thelma and Ricky. With a M.S. degree in chemical weed control from UW-Madison, grazier David especially enjoys being an owner member of Organic Valley.

Andy farms in Green Bay, WI on 216 acres that he rents from his parents. He began to handle management and operations of his parents’ organic beef and crop farm in 2008. With an interest in Dairy, he began working as a relief milker at Full Circle Farm in Seymour, WI. In 2011, Andy entered into a share milking arrangement with Full Circle Farm where he furthered his knowledge and understanding of how to manage and operate a rotational grazed-organic dairy. In March of 2014 he moved his herd of 65 milk cows to his parent’s farm where he has set up a one-unity robotic milking facility to see if high tech milking technology has a place in the world of grazing. He continues to manage the herd organically with rotational grazing as a key element to his business model.
