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.
There are lots of gardening tasks to complete in April, including fertilizing your lawn and preparing soil and raised garden beds. Learn more in this guide.

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.
