Soil, water and topography maps — more commonly know as SWAT Maps — are becoming a familiar management tool for corn producers.
These high-resolution soil foundation maps are used to execute variable rate fertilizer, seed, soil amendment and pesticide applications. On this episode of the RealAgriculture Corn School, host Bernard Tobin catches up with Sullivan Agro’s Paul Sullivan as he is putting SWAT Maps to work in one of his clients’ fields.
Sullivan Agro began mapping client farms in 2021 and are now managing fields based on insights gleaned from the maps.
In the video, Sullivan describes how he used SWAT Maps to identify 10 unique production zones within the Arnprior, Ont., field and how variable rate planting and nitrogen scripts have been developed and applied to optimize production in each zone.
Sullivan heads into the field to evaluate how corn is progressing throughout the different zones and shares why he feels more agronomists and farmers will look to SWAT Maps to help develop agronomic plans to manage crop production.
“This is an agronomist tool to apply fundamental agronomy to the variation and production potential that’s across every farm,” says Sullivan. It’s a concept that farmers are very comfortable with and a great way to manage inputs based on the field and the growing season, he adds.
