rooting zone and end up in the groundwater that
supplies your drinking water.
"This study examines the ways in which land-use regulations in general and Oregon's land-use planning system in particular may affect property values. The study is focused on Oregon, but it is framed within the broader context of research in economics. Our analysis of Oregon land value data finds no evidence...
This publication addresses factors that farmers must consider when planning an on-farm composting enterprise: the composting process and its impact on water quality, site selection, facility layout and design, composting methods, and managing water and leachate. The content pertains to small and medium-size on-farm composting enterprises that handle about 100...

Soil acidity, expressed by low soil pH, causes reduced crop growth and significant economic loss. It is the most commonly overlooked and poorly understood yield-limiting factor in western Oregon and a developing concern in eastern Oregon. This publication describes the concept of soil acidity and the limitations it causes for...
