Whether a business owner, manager, or investor, you're undoubtedly concerned with achieving maximum profit and maintaining effective management. One way to measure these two standards is by using return on investment (ROI), the most commonly used indicator of company profit and management performance. Knowing the ins and outs of ROI is essential, and while it's easy to understand the importance of this concept, it's not always easy to understand ROI itself. Understanding Return on Investment clarifies and explains all the fundamental elements of this important financial tool, making it one you can use comfortably and successfully. Written by two authorities on the subject, this comprehensive guide explains in detail all major aspects of figuring and analyzing costs versus returns of projects and acquisitions. With charts, graphs, and examples drawn from actual companies, Understanding Return on Investment shows you what the two major components of ROI are, where they originate, and how they should be controlled in your business. It highlights the various forms of ROI, including GMROI (gross margin return on investment) and CMROI (contribution margin return on investment), and how they provide different measures for evaluating investment activities. It covers the DuPont system of financial control, ROI's relationship to return on equity (ROE), solvency ratios, and decentralized management.

High yields and environmental control in crop farming call for precise adaptations to local growing conditions. Treating large fields in a uniform way by high capacity machinery cannot be regarded as a sustainable method for many situations. Because differences existing within single fields must be considered. The transition from former field work carried out manually or by small implements to present day high capacity machinery caused that the farmers lost the immediate and close contact with soils and crops. However, modern sensing and controlling technology can make up for this deficit. High tech methods that include proximal sensing and signals from satellites can provide for controls that allow adjusting farming operations to small fractions of one ha and sometimes even down to some m2, hence in a site-specific mode. This applies to operations for soil cultivation, sowing, fertilizing and plant protection. This book deals with concepts, applications and results, and has an interdisciplinary approach that pervades all chapters.

"From the East Coast to the Mississippi River, from southern Canada to northern Florida, the eastern deciduous forest of North Americas is home to a wonderfully diverse range of wildlife and ecosystems. Richard H. Yahner integrates basic biological principles into an account of the ecological consequences of society's actions. As Yahner traces the history of conservation of the forest, he discusses relevant issues such as the loss of biodiversity, acid deposition, ozone depletion, and global climatic change. This new edition includes the most up-to-date information on the forest and its wildlife, with special attention given to contemporary conservation issues."--BOOK JACKET.
