Poison oak plants contain a chemical that causes a severe rash. Learn how to spot a plant, safely remove, and clean your clothes, gear and skin afterward to prevent a rash.
Silage-making has been used to reduce the concentrations of toxins in a variety of crops. But in the case of poison hemlock, the opposite is true — making silage out of it actually increases one of its toxic alkaloids.

Inadequate water intake by beef cattle can limit growth and production, which can translate to narrower profit margins for producers. That's why it's important to understand water nutrition and quality for beef cattle.

It’s important to keep food safety in mind when storing herbs or vegetables such as garlic, mushrooms and chili peppers in oil. The combination of these low-acid foods and oil create an environment for deadly bacteria.
This collection of links and publications are compiled information about managing nutrient levels in your pasture. This includes soil testing and assessment, application of fertilizers and minerals, and nutrient cycling in a forage pasture.
The Oregon State University Soil Fertility Program has completed a formal evaluation of the Sikora buffer to replace the SMP buffer for estimating lime requirement in Oregon. Twenty-four acidic soils from Oregon were tested for actual lime requirement using a lab incubation of lime and soils. The actual amount of lime needed to reach pH targets of 5.6, 6.0, and 6.4 was highly correlated to the SMP buffer (r2 = 0.91-0.93) and the Sikora buffer pH (r2 = 0.91-0.93). These correlations are the basis for new updated lime recommendations for both Sikora and SMP buffer pH methods (Table 1) and will be used to update OSU extension guides containing lime recommendations. The new SMP recommendations are included for the time being for the remaining labs still using the SMP method, but may be phased out over time as more labs switch to Sikora. We thank the Oregon Tall Fescue Commission for providing the necessary support to complete this project.
Q: The straw mulch I used at the end of summer to suppress the weeds doesn't seem to be working. Should I till it and cover with plastic? black or clear? Is there something better. Or should I add more straw. I could probably bring some cardboard home from work. Is this a healthy option?
Q: Several brown, dead rings have formed in my lawn this summer. They seem to coincide with a type of mushroom. Are the mushrooms causing this? Is there any treatment short of applying a fungicide that is effective? Will the lawn recover on its own?
