  • Preventing and Extinguishing Hay Fires

    Preventing and Extinguishing Hay Fires

    Key Points: What Causes Fires? The process of forage heating up and then burning is typically called spontaneous combustion. Spontaneous combustion for hay usually occurs within the first two months of storage. Unusual growing conditions, such as an early harvest window or immature crop, can complicate the drying process and increase the risk of fire.…

  • 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…
