Nutrient management and cycling in grass seed crops

Creator:: Horneck, Donald Arthur
Abstract:: Grass seed production in Oregon's Willamette Valley traditionally relied on open field burning for straw residue disposal and nutrient recycling. Changes in residue management from open field burning to methods that remove straw coincided with rapidly declining K soil test values. A survey of grass seed fields showed that many...

Field microplot estimates of soil N mineralization for manured and non-manured soils

Creator:: Sullivan, Dan M., Cogger, Craig G., Bary, Andrew I., and Myhre, Elizabeth
Abstract:: Credits for available N from past manure applications are often used in nutrient management planning. However, it is difficult to verify the accuracy of these credits. The major objective of this study was to estimate long-term effects of manure application on soil N mineralization. Specific objectives were to: 1) estimate...

Ionic balance and organic acids in western redcedar, western hemlock, and Douglas-fir seedlings grown in low- and high-N soils

Creator:: Graff, J. E., Hermann, Richard K., and Zaerr, J. B.
Abstract:: Seedlings of western redcedar (Thuja plicata Donn ex. D. Don), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were transplanted into soils with low and high levels of available NO3 – (and total N). Current-year foliage was sampled after 10 weeks to determine the effect of...

Nitrogen uptake and utilization by Pacific Northwest crops

Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, Sullivan, Dan M. (Dan Matthew), 1954-, Hart, John M. (John Mervyn), 1947-, Christensen, Neil Walter, 1944-, and Pacific Northwest Cooperative Extension
Abstract:: This publication provides information on the timing and pattern of biomass accumulation and nitrogen (N) uptake for a variety of Pacific Northwest crops. You can use this information to schedule N fertilizer applications for maximum efficiency. To achieve near-maximum crop yields, an adequate supply of available N must be present...

Effects of boron rates and differential irrigation on bush green beans and cauliflower

Creator:: Grealish, William J.
Abstract:: Five boron rates and seven water levels were applied to bush green beans (Phaseolus vulqaris cv Oregon 91G) and to cauliflower (Brassica olereacea var. botrytis, cultivar "Snowball Y") in 1989 and 1990 to evaluate their effects on total yield of both crops and on outer quality, head hollowness and internal...

Pears [1997]

Creator:: Hart, John M. (John Mervyn), 1947-, Righetti, Tim, Stevens, Bob, Stebbins, Bob, Lombard, Porter, Burkhart, David J., and Van Buskirk, Phil
Abstract:: Fruit tree fertilization is a standard grower practice intended to supplement soil-supplied nutrients. Both soil-applied fertilizers and nutrients stored within the tree are important. Tree reserves are the major source of nutrients for developing tissues before petal fall. Current-season growth and yield are influenced by nutritional status, which in turn...
