Designing Test Plots

On-farm test plots can provide valuable information about the performance of a product or practice. When designing a trial, it’s important to have a goal in mind, avoid confounding factors, test in fields that reflect local conditions and minimize variability between the factors tested…Read more

Three Factors That Limit Continuous Corn Yields

Obtaining maximum yields can be difficult in continuous corn production. Numerous studies have documented yield reductions when corn follows corn rather than soybeans. An Illinois study revealed three factors that explain 99% of the difference between continuous corn and corn-soybean results: soil nitrogen supply, continuous corn history and weather conditions…Read more

Weed Management in the Era of Glyphosate Resistance

The development of glyphosate-resistant crops is one of the most important weed management innovations in recent memory. Ease of use coupled with the broad-spectrum efficacy made it a popular choice among farmers. However, all herbicides are susceptible to resistant weed development given time and repetition. Overreliance of any weed management tool eventually leads to failure. Adopting best management practices helps prolong the useful life of current herbicides…Read more
