Book excerpt: Excerpt from The Use of Aromatic Solvents for Control of Submersed Aquatic Weeds in Irrigation Channels Thorough dispersion of the chemicals in the water before coming into contact with weed growth was of utmost importance. Aromatic solvents are lighter than water. Unless completely dispersed, the emulsions did not extend to the bottom of the channel but tended to break up more rapidly, allowing the solvent to rise to the surface and evaporate. With conventional spray units, the introduction of chemicals im mediately above a weir or other structure, with a considerable drop and turbulent pool, usually promoted adequate dispersion (fig. In the absence of such structures, compressed - air booms, attached to large compressor units. And placed in the water immediately below the spray boom, provided agitation and chemical dispersion. The advantage of mixing the aromatic solvents with water prior to intro duction under high pressure has already been discussed in the section titled Equipment for Application.

Available in PDF, EPUB and Kindle. Book excerpt: Irrigation came to the arid West in a wave of optimism about the power of water to make the desert bloom. Mark Fiege’s fascinating and innovative study of irrigation in southern Idaho’s Snake River valley describes a complex interplay of human and natural systems. Using vast quantities of labor, irrigators built dams, excavated canals, laid out farms, and brought millions of acres into cultivation. But at each step, nature rebounded and compromised the intended agricultural order. The result was a new and richly textured landscape made of layer upon layer of technology and intractable natural forces—one that engineers and farmers did not control with the precision they had anticipated. Irrigated Eden vividly portrays how human actions inadvertently helped to create a strange and sometimes baffling ecology.

Book excerpt: The widespread use of chemicals to control pests has resulted in adverse effects for both wildlife and humans. Originally published in 1967, this title seeks to clearly explain the key issues for understanding public policy in the pesticide problem. Authors Headley and Lewis provide simple clarification of the economic issues involved in creating public policy for pest control and present how policy formation for pesticides will be improved by further economic analysis. This title is a valuable and relevant resource for students interested in environmental studies, especially the impact of public policy making on the environment.
