Abstract:
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 as Mn toxicity are probably
less severe than for many soils with comparable pH values. Therefore,
lime responses at this location might be less than would be expected for
many Willamette Valley soils.
