Abstract:: An estuary, unlike the open ocean, is a dynamic system that is continuously undergoing changes in its physical and chemical properties. Marked fluctuations in the levels and kinds of nutrients, temperature, and salinity are normally found in estuarine environments. These changes occur principally as a result of freshwater intrusions, tidal...

Abstract:: Long-term experiments were started at Pendleton and Moro, Oregon in the 1930's to evaluate the effects of tillage, fertilizer, and residue management on crop productivity in non-irrigated semi-arid regions. Coupled with multi-year varietal improvement, rotation, and green manure studies, they define those practices which sustain soil productivity and improve crop...

Abstract:: In a series of 30 winter wheat fertilizer experiments conducted in the Willamette Valley between 1963 and 1969, optimum rates of nitrogen fertilization varied from 75 to 150 pounds per acre. Fertilization with N, particularly at the-higher rates, increased the protein content of the grain. Spring-applied N gave greater yield...
