Available in PDF, EPUB and Kindle. Book excerpt: Trends in Airborne Equipment for Agriculture and Other Areas is a collection of papers presented at a Seminar on Techno-economic Trends in Airborne Equipment for Agriculture and other Selected Areas of the National Economy (Aero-agro '78), organized by the United Nations Economic Commission for Europe and held in Warsaw, Poland, on September 18-22, 1978. Contributors examine the role of airborne equipment in agriculture and other areas from the perspectives of economic, technical and environmental concerns. Attention is paid to the value of soil surveys and land evaluation maps and of biogeographical analyses of pest outbreaks in planning aerial application operations. This book is comprised of 45 chapters and begins with a discussion on the economic aspects of airborne equipment, with emphasis on the value of bio-aeronautics in crop production and protection and of aircraft in the management of biological resources. Among the many techniques to improve economic efficiency, speed and timing are highlighted. The technical design and operation of equipment for aircraft are also considered, along with the use of helicopters as airborne cranes for a wide range of applications such as building construction and geological surveys. The results of experiments on the corrosive effects of pesticides, both in water and oil suspensions, are presented. A non-polluting insecticide particularly suited for ultra-low volume operations is also described, together with the use of light aircraft for fighting forest fires. This monograph will be a valuable resource for economists and agriculturists as well as policymakers in both areas.

Book Synopsis Evaluating the Effectiveness of Postfire Rehabilitation Treatments by : Peter R. Robichaud

Available in PDF, EPUB and Kindle. Book excerpt: Spending on postfire emergency watershed rehabilitation has increased during the past decade. A west-wide evaluation of USDA Forest Service burned area emergency rehabilitation (BAER) treatment effectiveness was undertaken as a joint project by USDA Forest Service Research and National Forest System staffs. This evaluation covers 470 fires and 321 BAER projects, from 1973 through 1998 in USDA Forest Service Regions 1 through 6. A literature review, interviews with key Regional and Forest BAER specialists, analysis of burned area reports, and review of Forest and District monitoring reports were used in the evaluation. The study found that spending on rehabilitation has increased to over $48 million during the past decade because the perceived threat of debris flows and floods has increased where fires are closer to the wildland-urban interface. Existing literature on treatment effectiveness is limited, thus making treatment comparisons difficult. The amount of protection provided by any treatment is small. Of the available treatments, contour-felled logs show promise as an effective hillslope treatment because they provide some immediate watershed protection, especially during the first postfire year. Seeding has a low probability of reducing the first season erosion because most of the benefits of the seeded grass occurs after the initial damaging runoff events. To reduce road failures, treatments such as properly spaced rolling dips, water bars, and culvert reliefs can move water past the road prism. Channel treatments such as straw bale check dams should be used sparingly because onsite erosion control is more effective than offsite sediment storage in channels in reducing sedimentation from burned watersheds. From this review, we recommend increased treatment effectiveness monitoring at the hillslope and sub-catchment scale, streamlined postfire data collection needs, increased training on evaluation postfire watershed conditions, and development of an easily accessible knowledge base of BAER techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.
