SWAT 020: Population Trials with Paul Sullivan of P.T. Sullivan Agro

SWAT Agronomy

Paul Sullivan (Twitter/X) joins the show to talk about the challenges he and his farmers are dealing with in his area of Eastern Ontario. We discuss some really interesting population trials that he’s doing, fertility issues coming off years of high fertilizer prices, and what difference SWAT MAPS has made for him and his farmer customers.

“When we look at yield, yield is a component of kernel number times kernel weight, and that gives us basically yield per acre. So with the definition of the SWAT MAPS we feel those yield components, we can kind of connect the genetics with the water supplying capacity in addition to the management of the farm.” - Paul Sullivan

Paul is a certified crop consultant and agronomist in Eastern Ontario. He has operated his agronomy services firm, PT Sullivan Agro, since 1997, and started using SWAT MAPS in recent years. His area of the province, which is just outside of Ottawa, is mostly corn, soybeans and wheat. Paul’s work focuses on developing crop plans around nutrient management, pH, pesticides, and some genetic recommendations as well.

Before starting the business, Paul spent eight years as a soil and crop advisor with the ministry of agriculture and food covering three counties with the provincial extension group there. So he has a long history of working directly with farmers to solve agronomic problems.
