Download or read book Soils and Their Properties (Classic Reprint) written by William Fream and published by Forgotten Books. This book was released on 2017-12-26 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soils and Their Properties The recognition of the work done by micro-organisms marks a most important advance in our knowledge of the phenomena involved in the metabolism (gr. Metabole, change) of the' soil. Hitherto, investigation has been directed rather to the determination of the immediate effects of soil metabolism in promoting the nutrition of plants. But it is at least possible that the biological fac tors in metabolic activity may eventually be proved to be not less potent than the physical and chemical agents in effecting the disintegration of rocks, and thus in restoring to the soil those mineral ingredients which are undergoing incessant loss. Our knowledge of the biology of the soil is hardly yet in a sufficiently settled condition to be made the subject of an elementary manual. All that is attempted, there fore, In 'the following pages is to trace soils back to their parent rocks, to indicate some of their more important physical and chemical properties, and to give a brief account of the distribution of soils within the British Isles. It is proposed to follow this Volume with another, in the same series, upon the practical management of the soil.

Book Synopsis Effect of Soil Types Upon Growth and Variation in Oats (Classic Reprint) by : Earl Jerome Grimes

This book was released on 2018-04-29 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Effect of Soil Types Upon Growth and Variation in Oats It has long been contended by various investigators that soils and climate are the main causes of environmental variations among plants. But it is not yet definitely known whether differences in amount of plant food or other soil conditions produce important permanent changes in habit; that is, mutations. Of the two factors, climate seems to be the more effective in producing variations in physical structure as well as chemical composition of the plant. This matter has received considerable attention by investigators especially in connection with the protein content in wheat. The study of the effect of environment upon the morphology and anatomy of plants has received relatively little attention. It perhaps more properly belongs to the realm of the ecologist but the problem is so closely related to plant breeding as to be practically inseparable.

Book Synopsis Composition of Hawaiian Soil Particles (Classic Reprint) by : Wm T. McGeorge

This book was released on 2018-03-26 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Composition of Hawaiian Soil Particles One of the primary characteristics of Hawaiian soils is the wide diversity of types which makes difficult their classification according to the usual methods employed in soil surveys. A wide variation in chemical composition, as well as in physical properties, is found within very Short distances. During a recent investigation in this laboratory upon the determination of humus, the character of the clay in Hawaiian soils, as regards certain of its properties, was found to be radically different from that in mainland soils. Chief among these abnormal properties is the incomplete coagulation when coag ulants are added. This is especially true in case of addition of ammonium carbonate, which has been successfully used on mainland soils for the coagulation of clay in humus extracts. This peculiarity of the clay has led to a study of the composition of the coagulable and noncoagulable grains and a further investiga tion upon the composition of the clay, fine silt, silt, fine sand, and coarse sand separates in the important Hawaiian types of soil differ ing in color, chemical composition, and physical properties.

Book Synopsis The Color of Soils (Classic Reprint) by : William Orrin Robinson
Download or read book The Color of Soils (Classic Reprint) written by William Orrin Robinson and published by Forgotten Books. This book was released on 2018-03-18 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Color of Soils The color of soils has long occupied the attention of both geologists and agriculturists and has considerable importance theoretically and practically. Theoretically the color is of importance as a guide to the origin and processes involved in the formation of the soil and as an indication of the relative age of any particular soil. It is of practical importance because it determines to a greater or less extent the absorption of the sun's energy, and is often a guide to the drainage conditions, to the crop adaptations, and to the cultural methods best suited to the soil. It is the object of this bulletin to publish the results of an investiga tion-into the causes of certain colors in soils, and particularly the causes of differences in color between the popularly named red and' yellow soils in connection with the agricultural significance of Such differences. In, addition to this, certain of the chemical and physical properties of iron compounds and their solutions will be considered It must be recognized that soil colors are not pure colors, but at best are Shades and tints. Thus the material by which soils ordinarily considered red are colored is ferric ox1de, which itself is never a pure red, for it varies from dark brown to yellowish, and when in the soil it is further tinted and Shaded by other materials. When applied to soils the color descriptions used in this bulletin mean the tints and shades which for the sake of Simplicity are termed red, yellow, brown black, or Simple combinations of these.

Download or read book Chemical Nature of Soil Organic Matter (Classic Reprint) written by Oswald Schreiner and published by Forgotten Books. This book was released on 2017-11-19 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Chemical Nature of Soil Organic Matter Every soil investigator, whether it be the chemist, bacteriologist, or physicist studying some special problem, or the agronomist dealing with the general relation of soils to crops, sooner or later encounters difficulties that have their origin in the lack of knowledge of the chemical composition of the organic matter of the soil. Some organic matter is essential to make a soil of what would otherwise be pulverized and more or less hydrolyzed rock, and while there are some soils capable of growing crops that contain very small quantities of organic matter, on the whole the quantity of this material in average soils is considerable. Analyses have shown that the average organic content of the soils of the United States is per Cent and of subsoils per cent. This means 28 tons Of organic matter per acre in the first 8 inches of soil and 50 tons in the soil and subsoil together to the depth of 2 feet.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Organic Constituents of Soils The soil is not simple, but complex. The soil properties and functions are likewise complex, not simple. All of the investigators preceding me in this symposium have emphasized to you by their papers how complex the subject is and how much remains to be done before a clear insight is Obtained, but they have also shown to you clearly that a well-trained army of scientists is at work on the prob lems connected with soil fertility, applying. Thereto all the principles of modern science. The Old view was simplicity itself; the soil was a mere trough in which the plant found its nourishment. But I can do no better than to let Liebig speak for himself. I quote from Letter XII of his Familiar Letters on Chemistry A field in which we cultivate the same plant for several successive years becomes barren for that plant in a period varying with the nature of the soil; in one field it will be three, in another seven, in a third twenty, in a fourth a hundred years. One field bears wheat and no peas; another beans and turnips but no tobacco; a third gives a plentiful crop of turnips but will not bear clover. What is the reason that a field loses its fertility for one plant, the same which at first flourished there? What is the reason one kind of plant succeeds in a field where another fails?
