As ornamental container nurseries face diminishing water allocations, many are looking to automated irrigation solutions to increase their water application efficiency. This thesis presents the findings of a study conducted at a commercial container nursery to determine 1) whether a capacitance or load cell sensor was better suited for monitoring...
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...
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.
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...
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...
Several investigators have recently called attention to the
fact that the flux equation for water movement in unsaturated soils
may not be an appropriate mathematical model for the development
of the theory of unsaturated flow phenomena.
An analytical theory is developed for the purpose of testing
the validity of the...
In previous research, bromacil gave good performance when
it was applied in early fall with fairly dry soil conditions and before
the fall germinating weeds had started growth. On the other hand,
if bromacil was applied in late November, December, or January
on nearly saturated soil with weeds that had...
