The US Army, Army Reserve, and Army National Guard Engineer units are involved in a joint US/Honduran venture to develop the infrastructure of Honduras. As part of the venture, several roads and airfields are being constructed. This construction has led to improved commerce in several areas of the country, but has also produced dust and erosion problems. Dust on road ways impairs driver visibility and can create serious safety hazards. Erosion of banks and slopes by runoff water has led to roadway failures. Exposed soils on or adjacent to runways are susceptible to erosion from wind and rotor- or propwash, creating hazardous conditions for aviators and increasing aircraft maintenance cost. The problem is to control dust and to reduce or eliminate the erosive effects of runoff economically while using assets available in-country. Keywords: Erosion control; Circuit engineering.

Common Grasses, Legumes and Forbs of the Eastern United States: Identification and Adaptation presents photographic identification of the most important grassland, turf, and noncrop plants, and their seeds to facilitate quick identification in the field. Unlike many publications that focus solely on floral identification, this book emphasizes vegetative identification as well to allow for accurate plant identification year-round. The book includes 23 forage legumes, 61 grasses, and more than 100 nonleguminous forbs found in pastures and grasslands of Eastern United States. In addition to identification of important species, the book describes other key characteristics such as adaptation, favorable and unfavorable soil types, seasonal growth patterns, and toxicity. For plants harvested for hay or silage or by grazing, the book also discusses cutting and grazing management, quality factors, and potential yields. Through its practical approach and comprehensive structure, Common Grasses, Legumes and Forbs of the Eastern United States is a valuable reference for farm advisors, teachers and students of agronomy, and for anyone interested in the dynamic relationship between plants and agriculture. Features full-color illustrations of both seed and plant, allowing for rapid identification at multiple stages of development Presents various identification methods and use cases for over 180 plants Details seasonal growth patterns and toxicity, as well as favorable and unfavorable soil types Discusses cutting and grazing management
