Soybean School: The Costs of Continuous Soybeans

Tough conditions last fall resulted in fewer acres of wheat being planted than planned in Ontario. Some of those fields could end up defaulting back to soybeans for 2015.

In this Soybean School episode, Dave Hooker, field crop agronomist and assistant professor at the University of Guelph-Ridgetown, and Bernard Tobin discuss the implications of back-to-back soybean crops, and how the effects differ in no-till versus conventional tillage systems.

“As the frequency of soybeans increases in a rotation, it cuts back on our soybean yield. That holds true for both no-till and conventional systems, but it seems to be more dramatic in a conventional till system, and that’s because of the impact tillage has on soil quality,” says Hooker, citing research from Ridgetown and the University of Wisconsin.

Soybean acres exceeded the 3 million mark in Ontario for the first time last year. A similar number of acres are expected in 2015.
