Estimating soil moisture by feel and appearance
This publication provides direction on estimating soil moisture by the "feel and appearance" method; taking a some soil and rolling it up in a ball then squeezing it between your thumb and forefinger to form a ribbon and noting how it appears and feels. Compare what you see with photographs and/or charts to estimate percent water available and the inches depleted below field capacity.
Low energy precision application (LEPA) and low elevation spray application (LESA) trials in the Pacific Northwest
LEPA and LESA are alterations on a center pivot where the sprinklers are moved much closer to the ground, the spacing between sprinklers is reduced (more sprinklers), and water is emitted at very low pressures. It saves water (18%), it saves energy (less water pumped and pumped at a lower pressure), and it helps growers get better yields especially in areas where water ...
New analysis reveals challenges for drought management in Oregon’s Willamette River Basin
In Oregon’s Willamette River Basin, managing water scarcity would be more effective if conservation measures were introduced in advance and upstream from the locations where droughts are likely to cause shortages, according to a new study.
