Laboratory soil tests help you develop and maintain more productive soil and increase crop production by providing information on the available nutrient content of your soil. Soil testing helps you select the correct kind and amount of fertilizer and liming material. Recommendations are based on the results of fertilizer experiments,...
Periods of precipitation with certain combinations of characteristics

The occurrence of frozen soil has a major effect on runoff and soil loss
in the Pacific Northwest. Hence, information regarding the probabilities of
occurrence of periods during which the soil may be frozen is necessary in order
to adequately forecast long-term erosion rates for this region. In order to...

Alfalfa is an extremely important crop in the agricultural economy of Central Oregon. Some of the alfalfa is fed in livestock operations on the farms where it is produced, but most of it is sold as baled hay for use in other parts of the state and region.
Annual yields...
Alfalfa hay yields in Central Oregon are only about one-half of their potential level. Annual yields of 4 to 5 tons per acre have been considered to be very good, but if the best known establishment and management practices are conscientiously applied, much higher yields are possible. Studies done at...
