What impact do higher-yielding corn crops have on no-till soybeans?
That's a question many growers are asking as they prepare to plant no-till soybeans into high levels of corn residue that can keep soil cooler in spring, impact emergence and reduce stands. Growers also have to contend with soil compaction caused by difficult harvest conditions that can hinder soybean growth.
On this episode of the RealAgriculture Soybean School, Ontario Ministry of Agriculture, Food and Rural Affairs soil management specialist Jake Munroe joins host Bernard Tobin to share his take on how big corn crops affect no-till soybeans.
In 2022, Munroe followed a series of no-till soybean fields to determine how a record 2021 Ontario corn yield, and a wet, difficult harvest season that produced significant soil compaction, impacted the following soybean crop.
In the video, Munroe shares how he monitored five fields in southwestern Ontario, spanning three counties - Huron, Wellington and Brant. Each field had been under a reduced tillage system across the full rotation for seven years or more.
