Between October 2016 and October 2017, four regional meetings were held around the United States between small and very small meat processors, high-ranking USDA Food Safety Inspection Service (FSIS) officials, and other local meat sector stakeholders and support organizations. The purpose of the meetings was for FSIS officials to tour...

The market for organic vegetables is increasing. As conventional farmers transition fields to organics to meet this demand, there is a need for better organic nutrient management guidance, especially for nitrogen (N). Organic N management is more challenging than conventional N management due to a higher level of uncertainty surrounding...

Urea is a common nitrogen fertilizer for sweet corn production. This two year project evaluated commercially available urea additives for their potential to provide crop production and environmental benefits. Specifically, experiments were designed to evaluate the efficacy of urea fertilizer products containing a urease inhibitor (Agrotain Ultra), or nitrification inhibitors,...
This publication covers how pasture grows, understanding grazing systems, and forage quality. It also covers advanced tools for managing high-intensity grazing systems, such as the feed wedge (also called pasture wedge or grazing wedge).

Enhanced efficiency fertilizer (EEF) technologies have the potential to improve the crop N use efficiency (NUE) as well as minimize negative environmental losses compared to conventional fertilizers. The EEF fertilizer products consist of urea plus additives (to inhibit N loss). The major pathways for N loss in our sweet corn...
The overall objective of this multi-year project is to maximize nutrient use efficiency without compromising bean yield and quality. This year’s project objectives were to: 1) evaluate crop response to P fertilizer at current soil P test levels in grower fields; 2) generate phosphorus (P) potassium (K), and nitrogen (N)...

Although Oregon is the #2 snap bean producer in the US, yield of snap beans per acre is greater in Oregon than any other state (USDA NASS 2012). Despite the scale and importance of snap bean production in Oregon, almost no research has been done on phosphorus (P) utilization over...
The enhanced efficiency (EEF) products we tested in our study hold the potential to increase the nitrogen utilization efficiency of sweet corn as well as reduce nitrate leaching when all N fertilizer is applied before planting. However, this potential is limited by weather (i.e. large early season rainfall events), irrigation...

Peppermint residue consists of the cooked leaves and stems of the peppermint plant after high-temperature distillation to extract oil. This residue has value as a soil amendment. It is often applied to fallow fields in the fall or sold as a soil amendment to gardeners. Research was conducted to determine...

The purpose of this report is to document changes
resulting from long-term application of biosolids to
grazed dryland pasture. The report contains two chapters:
• Chapter 1: Biosolids Increase Grass Yield and Quality
in Dryland Pasture
• Chapter 2: Biosolids Increase Soil Fertility in Dryland
Pasture
Data summarized here was...
As a crop species, lupin was important to many ancient civilizations and has been cultivated, mostly as a green manure, for at least 3,000 years. Its native range extends through the western parts of North and South America as well as around the Mediterranean, extending into eastern Africa. Of the...

Extensive information on rootstock resistance to lime is available since it has been one of the major selection criteria in Europe an rootstock breeding programs. Information regarding the performance of rootstocks in acidic soils however, is not so prevalent. Differences in genotype tolerance to high acidity maybe related to different...
There is growing concern among producers regarding the sustainability of current dryland winter wheat cropping practices. This study looks at the economic viability of three wheat rotations currently being studied at the Columbia Basin Research Center in Pendleton, Oregon, including W IF and two alternative rotations, W/B/F and C/W/F. The...
This manual is designed to serve as a resource for those who organize and conduct training programs in biosolids management. It describes the process of organizing and conducting effective training sessions as well as the technical topics that should be covered.
Soil and vineyard vegetation management are tools that may be used to create stable growing conditions for the grapevine roots and to preserve soil fertility for high grape quality in future years. The use of cover crops is commonly practiced in viticultural areas where precipitation exceeds 600-700 min (24-28 in)...

During the 1994 growing season, 1,998 dormant wine and table grape cuttings and 2,552 mist propagated plants were distributed to 33 growers from the OSU Mother Block. Sixteen new clones were added to the Mother Block in early spring. This included rootstock, wine and table grape cultivars. The trellising system...
Forty perennial and 12 annual grass varieties were evaluated for seed production potential at Corvallis, Oregon. Perennial ryegrass, orchardgrass, Kentucky bluegrass, red fescue, Chewings fescue, tall fescue, and annual ryegrass were included in the study. Results of 1986 and 1987 harvest years are reported.
Research reported here was done by or in collaboration with the people listed on each report. In most cases, a landowner cooperated as well. Each study was conducted over a 2-year period because first-year control of perennial weeds is not necessarily indicative of long term control.
Oregon State University researchers are expanding their study of mineral nutrition in winegrapes as part of a project sponsored by the Wine Advisory Board. Further research is justified because of increasing grower interest in nutritional factors that affect production and quality. Winegrape growers utilize Oregon State University's Plant Analysis Laboratory...
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...
