Monitoring soil nutrients in dryland systems using management units

Creator:: Oregon State University. Extension Service, Corp, Mary K., Horneck, D.A., Wysocki, D., and Lutcher, L.
Abstract:: The use of management units for soil testing and nutrient application is an effective strategy to increase accuracy in monitoring and managing nitrogen (N), phosphorus (P), and other nutrients. A management unit can be a group of fields, a single field, or an area within a field. To measure changes...

Needle Sampling Dates for Nutrient Evaluation in Christmas Tree Production

Creator:: Hart, J. M., Landgren, C. G., Moody, J. T., Fletcher, R. A., and Horneck, D. A.
Abstract:: Christmas tree needle sampling to evaluate nutrient need is an established practice. Data to support the recommended fall sampling time in Oregon and Washington was not found. In addition, the recommendation for needle sampling of Fraser fir in North Carolina was made without data from winter months. The goal for...

Perennial ryegrass grown for seed (western Oregon) [2005]

Creator:: Hart, John M. (John Mervyn), 1947-, Mellbye, Mark Edward, Horneck, Donald Arthur, Gingrich, Gale Allen, Young, W. C., and Silberstein, T. B.
Abstract:: Perennial ryegrass is grown for turf or forage seed on a broad range of soils in western Oregon. All perennial ryegrass varieties are similar in their nutrient requirements. Typical seed yield is between 1,400 and 1,800 lb/acre. Higher seed yields (up to 2,500 lb/acre) may be produced on better soils,...

Using the nitrogen mineralization soil test to predict spring fertilizer N rate : soft white winter wheat grown in western Oregon

Creator:: Oregon State University. Extension Service, Hart, John M. (John Mervyn), 1947-, Christensen, Neil Walter, 1944-, Mellbye, Mark Edward, and Flowers, Michael Darrell, 1971-
Abstract:: Soft white winter wheat grown in western Oregon requires a spring application of nitrogen (N) fertilizer for optimum production. Determining the amount of N to apply has been a challenge for growers because wheat is produced in numerous rotations that provide varying amounts of N to the wheat crop. Inadequate...

Camelina: Seed Yield Response to Applied Nitrogen and Sulfur

Creator:: Wysocki, Donald J., Chastain, Thomas G., Schillinger, William F., Guy, Stephen O., and Karow, Russell S.
Abstract:: Camelina (Camelina sativa L. Crantz) has received worldwide attention in recent years as a biofuel crop and as a broadleaf option in cereal-based cropping systems. The objective of our 3-year study was to determine camelina seed yield and nitrogen use efficiency (NUE) as affected by six applied nitrogen (N) rates...

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...

Initial response of a mixed-conifer understory plant community to burning and thinning restoration treatments

Creator:: Wayman, Rebecca Bewley and North, Malcolm
Abstract:: Mechanical thinning and prescribed ﬁre are widely used to restore western forests after a century of ﬁre suppression, yet we know little about how these treatments affect understory communities where plant diversity is highest. We followed understory plants and environmental factors in old-growth, Sierran mixed conifer for two pre-treatment and...

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...
