This publication discusses the use of granular matrix sensors (GMS) for monitoring soil moisture content. It explains how to install GMS and use the recorded data for irrigation scheduling.
Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover
seed yields can be highly variable and low in western Oregon. The objectives of
this study were to: i) determine crop water requirements and supplemental
irrigation timing, and ii) quantify the effects of soil and water status on
inflorescence...
Explica el uso de los sensores matriciales granulares para la medición de la tensión de humedad del suelo. Explica cómo instalar estos sensores y cómo usar los datos registrados para la programación del riego. (Discusses the use of granular matrix sensors (GMS) for monitoring soil moisture content . Explains how...
Landscape heterogeneity is thought to differ among farm management types (i.e. organic and conventional), and this difference is hypothesized to result in variations in pest control by natural enemies. However, it is unclear if these variations in pest control are driven by landscape structure or by farm management practices themselves....
The study was conducted in an organic trailing blackberry (Rubus L. subgenus Rubus, Watson) planting established at the North Willamette Research and Extension Center in Aurora, OR on 26 May 2010. Three weed management systems were compared for 'Marion' and 'Black Diamond': 1) non-weeded; 2) hand-hoed two to three times...
Surface water in the Deschutes Basin of central Oregon has been largely over
allocated since the early 1900s. Therefore, rapid population growth and urban
demand for water in the upper Basin lead to an increased reliance on groundwater in
the last three decades. The Oregon Department of Water Resources (OWRD)...
Signs of climate change across the Pacific Northwest indicate changing patterns of timing and availability of stream flow. Declining summer low flows, decreasing snow pack, higher temperatures and an increasing fraction of mountain precipitation falling as rain, raise concerns about future reliability of stream flows. These changes will likely affect...
Some consideration has been given to the irrigation of winter
wheat in the Willamette Valley of Oregon. This important crop has
yielded quite well since the development and introduction of the
stiff-strawed, semi-dwarf wheats, but, because of the usually dry
early summers, it has been suggested that irrigation of winter...
The purpose of this study was to make a preliminary
investigation of the productivity of some of the soils
within the Willamette catena under different systems of
soil management. The study was carried out at four experimental
sites near Corvallis, Oregon, during the 1962 growing
season. The soil at each...
