Producers have questioned the conventional advice to apply lime to change the pH of coastal soils. We look at one set of data on ryegrass pastures that shows the return on investment may indeed be modest.
Q: I have heard about applying lime to my lawn and garden to improve my soil. Can I use the pictured product, and how would I apply it? There are no application directions.

While relatively healthy, forests in western Oregon face threats from climate stress, insects and disease. Here's a look at forest management strategies to cope with those threats and keep the state's forests healthy.

Pasture-based pork production offers opportunities for niche meat producers to meet the desires of consumers concerned about the treatment of animals they eat. But it's not as simple as just turning pigs out to 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.
