Greenhouses
A greenhouse provides an essential means of livelihood to its owner and must be economically practical for the particular climate in which it stands. Greenhouses: Advanced Technology for Protected Horticulture addresses the major environmental factors of light, temperature, water, nutrition, and carbon dioxide, and features extensive discussions of greenhouse types, construction, and climate control. The book highlights technology such as hydroponics, computer control of environments, and advanced mathematical procedures for environmental optimization. Greenhouses: Advanced Technology for Protected Horticulture is the definitive text/reference for the science of greenhouse engineering and ma...
The Garden Lover's Guide to the West
Our Garden Lover's Guide series has been hailed by Garden Design as "eminently practical" and by Home as "authoritative" and "indispensible." These three new volumes complete our survey of American gardens; together, the four books feature over 500 public gardens across the country.Each book is designed for readers to use as they travel through a state or region. Similar to our highly successful European garden guides, the U. S. guides are illustrated in full color with numerous photographic images and watercolor drawings of the most significant gardens, all specially commissioned for these books. In addition to insightful texts, contact data, opening hours, admission fees, and directions are provided. The perfect companion for any garden enthusiast, whether tourist or armchair traveler.

Electron Paramagnetic Resonance
This book offers a pragmatic guide to navigating through the complex maze of EPR/ESR spectroscopy fundamentals, techniques, and applications. Written for the scientist who is new to EPR spectroscopy, the editors have prepared a volume that de-mystifies the basic fundamentals without weighting readers down with detailed physics and mathematics, and then presents clear approaches in specific application areas. The first part presents basic fundamentals and advantages of electron paramagnetic resonance spectrscopy. The second part explores severalapplication areas including chemistry, biology, medicine, materials and geology. A frequently-asked-questions sections focuses on practicalquestions, such as the size of sample, etc. It's an ideal, hands-on reference for chemists and researchers in the pharmaceutical and materials (semiconductor) industries who are looking for a basic introduction to EPR spectroscopy.
High on a Windy Hill
This long out-of-print genealogical reference has become much sought after by residents of Washington County, Virginia, and the numerous scattered descendants of that county's forefathers. The work identifies 333 Washington County cemeteries and cites the inscriptions of each tombstone. Seven detailed maps aid in locating the burial sites. This edition also includes a newly compiled comprehensive index of more than 2,400 surnames, many of which include multiple entries.

Fertilization of Dryland and Irrigated Soils
Much has been learned about the proper and judicious use of fertilizers. Fertilizer application by farmers has grown from an art to a science. As food producers have strived to increase crop yields by overcoming nutrient deficiencies the use of fertil izers has increased dramatically. This has created a large chemical industry capable of supplying the needed plant food elements. A more complete understanding of soil chemistry and plant nutrition has led to greater fertilizer use with improved fertilization methods and crop cultural practices. Improved fertilizer technology has led to the production of more efficient forms of fertilizer. The modem fertilizer industry and with it fertilization practices began in the humid countries of the world. The use of fertilizers in arid and semiarid regions was later in development, although agriculture had its beginning in semiarid and arid regions. The development offertilizer use is parallel to industrial development in various areas of the world.
Insect Pest Management
Insect pest control continues to be a challenge for agricultural producers and researchers. Insect resistance to commonly used pesticides and the removal of toxic pesticides from the market have taken their toll on the ability of agricultural producers to produce high quality, pest-free crops within economical means. In addition to this, they must not endanger their workers or the environment. We depend on agriculture for food, feed, and fiber, making it an essential part of our economy. Many people take agriculture for granted while voicing concern over adverse effects of agricultural production practices on the environment. Insect Pest Management presents a balanced overview of environment...
Forest Nursery Manual: Production of Bareroot Seedlings
ing damage ranged from odor. to general visual appearance. Attributes of seedling quality are categorized as either to cutting buds. to scraping bark to detect dead cambium. performance attributes (RGP. frost hardiness. stress resistance) One nursery reported using frost hardiness as an indicator of or material attributes (bud dormancy. water relations. nutrition. when to begin fall lifting. but none reported using it as an morphology). Performance attributes are assessed by placing indicator of seedling quality before shipping stock to customers. samples of seedlings into specified controlled environments and evaluating their responses. Although some effective short 23.4.3 Stress resistance...
