The study of ecologically-based weed management approaches including cultural, mechanical, biological, and chemical control practices. The course addresses a major land resource issue in Montana and throughout the western U.S. Focus is on synthesizing science-based information into rangeland weed management plans. Microorganisms in soil environments, biochemical processes important in natural and disturbed ecosystems, nutrient cycling, transformation of inorganic and organic contaminants, and plant-microbe interactions. Soil physical properties and processes governing distribution and transport of water, heat, and soluble chemicals. Topics include water content and potential, infiltration, evaporation, temperature and heat flow, saturated and unsaturated water and chemical flow.
Laboratory stresses measurements and analyses.
Course will provide a brief review of fundamental biological, physical and chemical processes that control chemical fate in soil and water systems, followed by applications important for specific point and nonpoint source pollutants. Examples include soil acidification, bioremediation or organic contaminants, land application of animal and sewage wastes, and trace element problems in agricultural and mining systems. Course format will include lectures in addition to individual and team problem solving. LRES 452, LRES 453 or equivalent. Study and application of teaching philosophies and methods based on current literature or through individual presentations and discussion groups.
