Measurement and interpretation of physical properties of soils

Creator:: Nagpal, Narender Kumar, 1942-
Abstract:: One of many important physical properties that must be known to understand transport phenomena in soils is pore size distribution. Presently the pore size distributions of soils are most commonly obtained from soil water characteristic curves. The soil water characteristic curves are usually obtained by the pressure plate technique. It...

Penman-Monteith surface resistance for hybrid poplar trees

Creator:: Butler, Dana Anthony
Abstract:: The application of the widely used Penrnan-Monteith evapotranspiration equation to hybrid poplar trees is impossible without a valid surface resistance. The increase in applications of drip-irrigated hybrid poplar trees for wood chip stock and veneer production, as well as bioremediation, constitutes a need for estimating the evapotranspiration of these trees....

Irrigation monitoring using soil water tension

Creator:: Flock, Rebecca, Flock, Rebecca, Feibert, Erik, Shock, Cedric A., Pereira, Andre, Jensen, Lynn, and Oregon State University. Extension Service
Abstract:: 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...

El control del riego mediante la tensión matricial del suelo

Creator:: Shock, Clinton C., Flock, Rebecca, Feibert, Erik, Shock, Cedric A., Pereira, Andre, Jensen, Lynn, and Oregon State University. Extension Service
Abstract:: 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...

Using seed moisture as a harvest management tool

Creator:: Silberstein, Thomas B., Mellbye, Mark Edward, Chastain, Thomas G., Young, William C. (William Clyde), and Oregon State University. Extension Service
Abstract:: Seed moisture content is the most reliable indicator of seed maturity and harvest timing in grass seed crops. There are two significant times during harvest that knowledge of seed moisture is critical: at swathing and at combining. Swathing within the correct range of seed moisture content will maximize seed yield...

Towards autonomous irrigation : comparison of two moisture sensing technologies, irrigation distribution analysis, and wireless network performance at an ornamental container nursery

Creator:: Bailey, Daniel R.
Abstract:: 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...

Improving soil water determination in spatially variable field using fiber optic technology and Bayesian decision theory

Creator:: Sayde, Chadi
Abstract:: Achieving and maintaining sustainability in irrigated agriculture production in the era of rapidly increasing stress on our natural resources require, among other essential actions, optimum control and management of the applied water. Thus, a significant upgrade of the currently available soil water monitoring technologies is needed. The primary goal of...
Resource Type:: Dissertation
Full Text:: moisture measurements are quite uncertain. Some degree of uncertainty is intrinsic to the measurement

Evaluation of six tools for estimating woody biomass moisture content

Creator:: Becerra Ochoa, Fernando Amador
Abstract:: Woody biomass transportation costs and market values/costs are strongly correlated with the woody biomass moisture content. Properly managing moisture content can potentially lead to economic and environmental advantages in biomass energy markets. Good management requires accurate moisture content measurements. Therefore, availability of accurate, precise, reliable, and efficient tools to assess...
