The western states include a complex combination of geological, topographical, climatic, and vegetative features. The region extends through 1900 km of latitude and contains three major north-south, storm-directing mountain systems. Most of the region is arid (annual precipitation < 50 em); however, sizeable agriculturally important areas west of the Cascade...
Acidity distribution within any given soil profile is dependent on
mineralogical make-up of the parent material as well as environmental conditions prevalent during the weathering history of the soil.
An experiment was designed to study the distribution pattern of exchange acidity, exchangeable aluminum, exchangeable manganese and
pH of six acid...
The objectives of this investigation were to determine the effect
of pulverization on the strength, durability and swell characteristics
of a lime stabilized clay soil. Samples were prepared with three different
gradations which represented the pulverization of the soil.
Maximum clay lump sizes of 3/4", 1/2" and passing #4 sieve...
The application of lime to an acid Nekia soil significantly
increased the yield of winter wheat and alfalfa in a field experiment.
Crop yields maximized when the lime was partially mixed into the surface
four inches of the soil. Thorough mixing of the lime into the
surface six inches of...
Experiments at the North Willamette Experiment Station have evaluated response of vegetables to lime and other fertilizers since 1970. The soils are moderately acid (pH 5.4 to 5.6), high in P, and better drained than most soils used for vegetable crop production in western Oregon. Typical soil acidity problems such...
