One of the most important tools we have been using at the Malheur Agricultural Experiment Station over the past two decades is the granular matrix sensor (GMS, Watermark Soil Moisture Sensor, Irrometer Co., Riverside, CA), which measures soil moisture. It is only about 3 inches long and normally is buried...

Una de las herramientas más eficaces utilizadas por el Malheur Experiment Station durante las últimas dos décadas es el sensor matricial granular (o GMS por sus siglas en inglés), el cual mide la humedad del suelo. El sensor tiene sólo 7,5 cm de largo, y normalmente se entierra verticalmente en...
In the late 1980s, the U.S. Pacific Northwest potato industry faced a crisis. Potato tuber quality was inadequate to meet the needs of potato processing companies due to a condition called “sugar ends” or “dark ends” in fried tuber
slices. This defect was common in tubers grown on stressed Russet...
Cada año, grandes cantidades de suelo superficial son arrastradas por las aguas de riego. A través de los años, esta erosión puede resultar en una pérdida significativa de suelo en los campos agrícolas. Las investigaciones llevadas a cabo por Oregon State University Malheur Experiment Station y otros han demostrado que...
Irrigation scheduling is directly related to profitable onion production and sustainable agricultural practices. Research at the Oregon State University Malheur Experiment Station has demonstrated that onion yield and grade are very closely related to irrigation practices, especially the criterion used to schedule irrigations. Careful attention to irrigation scheduling can help...
This publication provides a framework, general recommendations, and rationales to aid potato growers interested in maximizing their land use and crop yield through drip irrigation. Discusses bed conformation, pumps and filters, system maintenance, microirrigation criteria, and chemigation.
