Book excerpt: Excerpt from Contributions to Our Knowledge of the Aeration of Soils The Object of this paper is to add to our information regarding the aeration of soils, primarily the escape of carbonic acid gas from its seat of formation in the soil, and the entrance of oxygen to take its place. The specific points treated are; (1) The relative importance of diffusion and of changes in barometric pressure; (2) the influence of texture, structure, and compactness; (3) the actual amounts of carbonic acid leaving and of oxygen entering the soil under definite conditions of temperature, porosity, and composition of the soil atmosphere.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Aeration and Air-Content: The Role of Oxygen in Root Activity In spite of the enormous amount of work done upon the respira tion of roots and the significance of soil-air, physiologists and eco logists generally have ignored this subject or have given it little consideration. A cursory survey of a score of text-books shows that the air-content of the soil is not even mentioned by the majority, while it is given slight attention by a few, and accorded recognition as a factor of primary importance by three or four only. This was probably a natural outcome of the laboratory development of physi ology. At least, it appears certain that the basic importance of the air-content of the soil could not be appreciated fully until ecology had begun the instrumental measurement of the habitat. Even the latter has found it difficult to distinguish between sequelae and causes in this field (plant Succession, p. And general recognition of air-content as a primary factor in many habitats, and a controlling one in wet soils and water, is yet to come. In the following treatise, the development of our knowledge of the respiration of roots and other underground parts is first taken up in historical sequence, together with an account of studies deal ing with the nature and composition of soil-air. This is succeeded by a digest of results in the field of anaerobic respiration, with especial reference to its relation to germination, growth, and move ment. A section is devoted to bog xerophytes and swamp plants, with which are considered bog toxins and acid soils, while soil toxins and toxic exudates are discussed in a final section.

Download or read book Bioavailability of Contaminants in Soils and Sediments written by National Research Council and published by National Academies Press. This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

Download or read book An Agricultural Testament written by Albert Howard and published by Distant Mirror. This book was released on 2021-04 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why is there a cow on the front cover of this book? This is a book about agriculture, and farm animals have become unfashionable in some quarters. Cows, it turns out, are responsible for global warming, climate change, and so, no doubt, rising sea levels and chemtrails. But any real farmer, from any time in history, knows that this is not true. Animals have been around forever. Animals are a vital part of an insanely complex living system. Anyone who knows the basics of regenerative agriculture understands this. Albert Howard spent years studying and using the methods of traditional Asian agriculture, and shows in this book that the fertility and health of the soil depend on humus, in the production of which animal materials play an vital role. A healthy soil needs animal inputs. Animals in agriculture are central; they're right in there with fungi. This message is not welcomed by those who would feed the modern world a diet of plant-based, lab-grown food substitutes that have lists of ingredients as long as your arm, and are going to save the planet using gene-spliced soybeans and 3D printed pizzas. So, the cow and her calf are on the cover to redress the balance, and also to feature as one of the stars of this book (along with sugar cane, waste pits, and public servants). She was the photogenic one. Albert Howard's text has been thoroughly re-edited in this new version of his book. The habit, common at the time, of using long paragraphs is not preferred by modern readers, so the text has been extensively 'reparagraphed'. Grammar has been tweaked, and styles have been adopted. Headings have been added, infinitives unsplit. The changes made have been to make things more comfortable for modern eyes and tastes. The sense and intention of the author has not been altered at all, of course. We hope that Albert Howard would approve of this reworking of his book. His ideas are more important than ever. Wendell Berry wrote in The Last Whole Earth Catalog "Howard's discoveries and methods, and their implications, are given in detail in An Agricultural Testament. They are of enormous usefulness to gardeners and farmers, and to anyone who may be interested in the history and the problems of land use. But aside from its practical worth, Howard's book is valuable for his ability to place his facts and insights within the perspective of history. This book is a critique of civilisations, judging them not by their artefacts and victories, but by their response to the sacred duty of handing over to the next generation, unimpaired, the heritage of a fertile soil."
