This publication describes—by climatic zone—perennial pasture plant growth and how management actions can affect growth, both positively and negatively. Optimal management of forages by season is the basis for the Pasture Calendar.
Assists livestock producers in using forage analysis as a management tool to improve livestock nutrition. Explains the information commonly found in most laboratory forage reports: feed, protein, carbohydrates, fat, energy, ash, minerals, pH, nitrates, RFV, and RFQ.
Pastures often contain weeds that are potentially dangerous to livestock. The toxic compounds in plants are usually a defense mechanism against predation and have a distinct, unpleasant odor or a bitter taste and are not ...

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. This study was conducted to provide a non-hazardous lime requirement testing alternative to the hazardous waste producing SMP method. 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.
With moderate to extreme drought coupled with forage yield significantly lower than normal, the availability of pasture and hay for sale is substantially less. Making plans to purchase feed may also lead to looking for alternative feeds or try these five other options.
