Book Description
Many agricultural fields are burned in the Willamette Valley of Oregon during the summer for economic reasons. A major air pollution problem results from these burnings. The purpose of this study was to develop relations between the maximum plume height and some of the independent variables affecting this plume height, such as, burn rate, wind velocity and atmospheric stability. By applying the proper relations found in this study, one could predict the maximum height a field burning plume would reach. The higher the plume rise, the lower the concentration of the plume effluents at ground level. If a relationship between the maximum plume height and the ground level concentration is known, for an accepted limit of ground concentration, the issuance of permission for the burning of a certain field could be given knowing the environmental variables. Three equations for different environmental conditions were developed through dimensional analysis. Their constants of proportionalities were obtained experimentally.

Grass Seed Acreage Response to Policies Concerning Field Burning

Category : Burning of land

Pages : 152

Book Description
This research analyzed the relationships of agricultural field burning policies, and other economic factors, with the quantity of land devoted to grass seed production in counties of the Willamette Valley, Oregon. The thesis describes the background of the grass seed industry, field burning and government policies concerning field burning in the Willamette Valley. Econometric models of acreage response to grass seed prices, prices of production alternatives, field burning limitations, and burning fees were developed for eight grass seed crops. A technique of pooling time-series and cross-sectional data was used to estimate the parameters of the models. Expost predictions of acreages were made for the purposes of model verification. The estimated parameters are discussed and some explanations are offered for the relationships.
