    Does it work to plant green into cover crops for corn? Five unique Ontario fields in 2023.

    Planting corn directly into a living cover crop before it is killed by herbicide or tillage is not something that would have been considered 30 years ago. However, with advances in planter technology, herbicide options, and a greater awareness of cover crop benefits to soil health, more growers are doing it. According to the 2022-2023…

    How to Make Annual Ryegrass Easier to Kill

    Co-authored by Mike Cowbrough, OMAFRA Weed Management Specialist – Field Crops An annual ryegrass cover crop is excellent at scavenging nitrogen, improving soil structure, and preventing erosion. It tolerates low light levels well enough to be inter-seeded into an established corn crop and grows quickly enough with adequate moisture to help suppress weeds. For ruminant…

  • When do cover crops, with and without manure applied, release nitrogen that can be used for my corn crop?

    When do cover crops, with and without manure applied, release nitrogen that can be used for my corn crop?

    Cover crops can produce nitrogen. We looked at when different species release nitrogen and the impact that adding manure has on the timing and release of nitrogen. The simple answer Predicting nitrogen (N) availability from cover crops is complicated. Cold and wet conditions in the spring negativelyimpact soil microbial activity and can result in significant…

  • When should I spray my cereal rye cover crop before soybeans?

    When should I spray my cereal rye cover crop before soybeans?

    Cereal rye is a versatile cover crop that can be seeded late into the fall in Ontario. Not to be confused with annual ryegrass – a grass that can be challenging to control – it is a winter cereal that overwinters reliably and grows rapidly in the spring. Delayed termination of rye by herbicide prior…

  • Is the yield potential of alfalfa increasing?

    Is the yield potential of alfalfa increasing?

    The relationship between alfalfa breeding efforts and yield potential is complicated. While most literature on annual grain crops shows yield improvements with the release of new varieties over time, a literature search on alfalfa yield will show improvement, stagnation, and declines, depending on the paper. One of the latest attempts to discern what is really…
