Soil water content and water potential are two important parameters in
determining the status of water in the soil. Improvement in the ability to measure these
parameters by way of increased speed, accuracy, resolution, imaging volume, ease of
automation, as well as reduced calibration requirements and reduced soil disturbance
would...
Prevention of groundwater contamination by agricultural
chemicals requires an understanding of the complex
processes that control pesticide movement below the soil
surface. Through this understanding it is possible to try
to predict which areas may be most vulnerable to

A lack of reliable criteria for designing tile drainage systems
in the Willamette Valley has lead to tile drainage installations in a
given soil series being based on general observations of previous
drain performance in the series. Relatively few quantitative measurements,
which would aid in designing economical installations,
have been...
