Good management practices are essential if optimum fertilizer responses are to be realized. The practices include use of recommended onion varieties, selection of adapted soils, weed control, disease and insect control, good seedbed preparation, proper seeding methods, and timely harvest. Because of the influence of soil type, climatic conditions, and...
We monitored the distribution, abundance and productivity of the federally threatened Western Snowy Plover (Charadrius nivosus nivosus) along the Oregon coast from 1 April – 15 September 2014. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North and South...
Laboratory incubation studies and field studies with sweet corn
and onions were undertaken to evaluate interactions of lime,
phosphorus (P), and copper (Cu). Eight soils were incubated at a
constant temperature of 21 °C with combinations of band placed
monocalcium phosphate (MCP), ammonium sulfate (AmS), and copper
sulfate pentahydrate (CSPH)...
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...
