Popular gardening advice touts the benefits of coffee grounds for acid loving plants, as a slug repellant and soil amendment. Little research based information is available to back up many of these claims. From November 2008 to September 2009 OSU Extension Service Master Gardener Compost Specialists in Lane County conducted an observational trial to see what the effect coffee grounds had on soil pH and nitrogen content when incorporated into soil.
Coffee grounds are a great addition to the garden and compost pile. Help to recycle this great organic resource and reduce the amount of organics going to the landfill!
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.
