Book Description
Plant production in hydroponics and soilless culture is rapidly expanding throughout the world, raising a great interest in the scientific community. For the first time in an authoritative reference book, authors cover both theoretical and practical aspects of hydroponics (growing plants without the use of soil). This reference book covers the state-of-the-art in this area, while offering a clear view of supplying plants with nutrients other than soil. Soilless Culture provides the reader with an understanding of the properties of the various soiless media and how these properties affect plant performance in relation to basic horticultural operations, such as irrigation and fertilization. This book is ideal for agronomists, horticulturalists, greenhouse and nursery managers, extension specialists, and people involved with the production of plants. * Comprehensive discussion of hydroponic systems, irrigation, and control measures allows readers to achieve optimal performance* State-of-the-art book on all theoretical aspects of hydroponics and soilless culture including a thorough description of the root system, its functions and limitation posed by restricted root volume* Critical and updated reviews of current analytical methods and how to translate their results to irrigation and fertilization practices * Definitive chapters on recycled, no-discharge systems including salinity and nutrition management and pathogen eradication * Up-to-date description of all important types of growing media

Book Description
“A Way to Garden prods us toward that ineffable place where we feel we belong; it’s a guide to living both in and out of the garden.” —The New York Times Book Review For Margaret Roach, gardening is more than a hobby, it’s a calling. Her unique approach, which she calls “horticultural how-to and woo-woo,” is a blend of vital information you need to memorize and intuitive steps you must simply feel and surrender to. In A Way to Garden, Roach imparts decades of garden wisdom on seasonal gardening, ornamental plants, vegetable gardening, design, gardening for wildlife, organic practices, and much more. She also challenges gardeners to think beyond their garden borders and to consider the ways gardening can enrich the world. Brimming with beautiful photographs of Roach’s own garden, A Way to Garden is practical, inspiring, and a must-have for every passionate gardener.

Book Description
Excerpt from The Uses of Peat: For Fuel and Other Purposes The Bureau of Mines is making a comprehensive investigation of the composition, heat value, and utility of the mineral fuels in the United States. In the course of its research the bureau is giving particular attention to methods of mining and utilizing fuels to the end that waste may be avoided and deposits of low-grade fuels now lying unmined may be made important assets of the Nation's mineral wealth. The investigation as a whole is a continuation of the testing and analyzing of fuels, as carried on by the United States Geological Survey, from the inception of the work in 1904 to the transfer thereof to the Bureau of Mines on July 1, 1910. In consequence of the transfer of authority this bulletin is published by the Bureau of Mines, though it was prepared under the direction of the Geological Survey. The bulletin sets forth the results of an investigation that was undertaken to determine whether peat, a fuel widely used in some countries, could be made serviceable in the United States, where, though labor and economic conditions differ from those in the peat-using countries, there are opportunities for the introduction of a fuel selling at prices that should make the mining and shipment of peat to near-by markets profitable. In connection with the investigation of the possibilities of utilizing peat as fuel, attention was incidentally given the possible development of other uses with the view of increasing the value of a material that hitherto has not been generally considered an important natural resource of the United States.
