Olive production potential in Oregon was researched in a multi-disciplinary approach, including a grower survey, a propagation greenhouse study, and a field study, from 2018 through 2020. The Oregon Olive Grower Survey was designed to collect information relating to orchard establishment and management practices, knowledge and understanding of these practices,...
Specialty organic fertilizers used in organic vegetable production are expensive. So, from environmental and economic perspectives, growers want to maximize nitrogen (N) fertilizer use efficiency by the crop. This research was conducted to (1) determine sufficient N fertilizer rates for organic broccoli, (2) evaluate the efficacy of a specialty organic...

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...
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).
Rangelands are significant providers of ecosystem services in agroecosystems world‐wide. Yet few studies have investigated how different intensities of livestock grazing impact one important provider of these ecosystem services—native bees. We conducted the first large‐scale manipulative study on the effect of a gradient of livestock grazing intensities on native bees...

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...
