A complicated topic is made easier with this title introducing roots and explaining their anatomy and how they help plants and soil. Labeled diagrams and photographs and a glossary will make learning about roots even simpler!

The term freezing to death is applied to a very specific set of phenomena in plants. With all plant tissues, when a certain temperature is reached very shortly after thawing, it will be found that the tissue has taken on a brown, water-soaked appearance, and evaporation from that tissue is much more rapid than from living tissue. In the experiments described in this paper, the killing temperature of plant tissue that kills at relatively high temperature has been reduced whenever the sap density of the tissue has been increased. Results of many investigations have shown that during freezing (which may or may not result in freezing to death), ice forms in the tissue, generally not in the cells but in the intercellular spaces, the water moving out of the cells to form crystals in these spaces. The most commonly accepted theory is that killing from cold results from the withdrawal of water from the protoplasm. The amount of water loss necessary to result in death varies with the different plants and different tissues. This paper studies the effects of cold weather on plant tissue, specifically concerning tissue death and the preventative measures that have been taken in the past and could be taken in the future. It is focused on Missouri apples, peaches, plums, and cherries.
Understanding Roots uncovers one of the greatest mysteries underground—the secret lives and magical workings of the roots that move and grow invisibly beneath our feet. Roots, it seems, do more than just keep a plant from falling over: they gather water and nutrients, exude wondrous elixirs to create good soil, make friends with microbes and fungi, communicate with other roots, and adapt themselves to all manner of soils, winds, and climates, nourishing and sustaining our gardens, lawns, and woodlands. Understanding Roots contains over 115 enchanting and revealing root drawings that most people have never seen, from prairies, grasslands, and deserts, as well as drawings based on excavations of vegetable, fruit, nut, and ornamental tree roots. Every root system presented in this book was drawn by people literally working in the trenches, sketching the roots where they grew. The text provides a verydetailed review of all aspects of transplanting; describes how roots work their magic to improve soil nutrients; investigates the hidden life of soil microbes and their mysterious relationship to roots; explores the question of whether deep roots really gather more unique nutrients than shallow roots; shares the latest research about the mysteries of mycorrhizal (good fungal) association; shows you exactly where to put your fertilizer, compost, water, and mulch to help plants flourish; tells you why gray water increases crop yields more than fresh water; and, most importantly, reveals the science behind all the above (with citations for each scientific paper). This book contains at least eighty percent more new information, more results of the latest in-depth and up-to-date explorations, and even more helpful guidelines on roots than the author’s previous book (Roots Demystified: Change Your Garden Habits to Help Roots Thrive). This is not a revised edition—it’s a whole new stand-alone book.
For decades fruit growers have sprayed their trees with toxic chemicals in an attempt to control a range of insect and fungal pests. Yet it is possible to grow apples responsibly, by applying the intuitive knowledge of our great-grandparents with the fruits of modern scientific research and innovation. Since The Apple Grower first appeared in 1998, orchardist Michael Phillips has continued his research with apples, which have been called "organic's final frontier." In this new edition of his widely acclaimed work, Phillips delves even deeper into the mysteries of growing good fruit with minimal inputs. Some of the cutting-edge topics he explores include: The use of kaolin clay as an effective strategy against curculio and borers, as well as its limitations Creating a diverse, healthy orchard ecosystem through understory management of plants, nutrients, and beneficial microorganisms How to make a small apple business viable by focusing on heritage and regional varieties, value-added products, and the "community orchard" model The author's personal voice and clear-eyed advice have already made The Apple Grower a classic among small-scale growers and home orchardists. In fact, anyone serious about succeeding with apples needs to have this updated edition on their bookshelf.
