This fact sheet is designed to help guide commercial hop growers in selecting cover crops. The guide discusses benefits and considerations or cons for four different cover crop strategies: annual fall planted, annual spring planted, annual re-seeding and perennial sod. Cover crop suggestions are tailored to western Oregon climate and regional cropping practices.
Poisonous plants are a major cause of economic loss to the livestock industry. Two poisonous plants common to Oregon are poison hemlock and Western water hemlock. Ingestion of either by humans or livestock typically results in death.
Poison hemlock is one of the most poisonous of plants. Silage making has been used to reduce the concentrations of toxins in a variety of crops. Poison hemlock alkaloids are found in different concentrations depending on several factors that make it virtually impossible to predict how dangerous the plant is at any given time.
