Book excerpt: Excerpt from The Principles of Soil Fertility Applied to the Worn-Out Dyked Lands To produce a large amount of available plant food a great many agencies must be brought into play. We can supply them directly in barnyard manure or in chemical fertilizers, whose chief value is bringing powerfully into play other agencies, and thus increase many fold a farmer's mastery of his conditions. By their wise use he can supplement nature's work and make them set free other chemicals for the use of his crops.

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?

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Principles of Soil Management In 1895 the preface was written for the Rural Science Series. It set forth the purpose of the Series to be the desire to place in readable form the best results of scientific thought and discovery relating to agriculture and country life, in order that the general public might be made aware of the progress, and that farmers might be led more effectively to apply the information in their daily work. It was the hope that the Series, under the present writer's direction or another's, might gradually extend itself to the whole range of agricultural scientific literature. The books now included in The Rural Science Series are about two dozen, making nearly two volumes, on the average, for each year. The number of writers on agricultural topics is increasing, the knowledge on all subjects is rapidly accumulating, and the reading-public is gradually enlarging; there is every reason to expect, therefore, that the Series will extend itself still more rapidly in the years to come. It was considered to be an auspicious circumstance that the Rural Science Series began with a book on the soil, for this grounded the enterprise.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Marion County Soils It is a matter of common observation that soils vary tremendously in their productive power, depending upon their physical condition, their chemical com position, and their biological activities. For any comprehensive plan of soil improvement looking toward the permanent maintenance of our agricultural lands, a definite knowledge of the various existing kinds or types of soil is a first essential. It is the purpose of a soil survey to classify the various kinds of soil of a given area in such a manner as to permit definite characterization for description and for mapping. With the information that such a survey affords, every farmer or landowner of the surveyed area has at hand the basis for a rational system of improvement of his land. At the same time the Experiment Station is furnished an inventory of the soils of the state, upon which intelli gently to base plans for those fundamental investigations so necessary for solving the problems of practical soil improvement. This county soil report is one of a series reporting the results of the soil sur vey which, when completed, will cover the state of Illinois. Each county report is intended to be as nearly complete in itself as it is practicable to make it, even at the expense of some repetition. There is presented in the form on an Appendix a general discussion of the important principles of soil fertility, in order to help the farmer and landowner to understand the significance of the data furnished by the soil survey and to make intelligent application of the same in the mainte nance and improvement of the land. In many cases it will be of advantage to study the Appendix in advance of the soil report proper. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Soil Fertility Classic Reprint written by W. C. Welborn and published by Forgotten Books. This book was released on 2017-10-29 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soil Fertility All plants are made up of substances taken from the earth and the air. The roots of plants absorb water from the moist soil, and with it some of the solid parts of the earth dissolved in the water. When a plant is burned, the ash remaining is composed mainly of what came from the earth during the growth of the plant. Plants, after becoming dry, have generally from 1 to 10 per cent of ash. The other 90. To 99 parts were derived from the air. Practically half the weight of dry plants is derived directly from the air through the medium of the leaves. All plant leaves absorb carbonic-acid gas - the gas that is used to charge mineral waters. This gas is easily produced by pouring strong acid on limestone. It is produced in nature on a vast scale by the burning and rotting of wood and other vegetable substances. It is also given off from the lungs of animals. When the leaves of plants absorb carbonic-acid gas from the air, the plants use the carbon (convert ing it into solid tissue), and give off oxygen gas, pure as originally. Oxygen for breathing is necessary to the life of man and animals. It is thus seen that animals and plants are dependent upon each other for the breath of life. This mutual dependence does not stop here. Animals must have certain salts which help to make up the solid parts of the earth, in order to live and grow. But man and animals can not digest stone or earth. These earthy salts must be taken into plants and be combined there into substances digestible and nourishing to animals. Then, the manure of animals is a good food for plants. When animals die their bodies also add fertility to the earth. That a farmer can not enrich the air with plant food so as to benefit his cr0ps is readily seen. This has been done successfully only in green houses, where the air can be controlled. All efforts in this direction must be mainly confined to adding plant food to the soil, or to improv ing the condition of the soil so that its own large stores of plant food may be more easily taken up by plants.

Download or read book Soil Fertility Second Edition written by Boyd Ellis and published by CRC Press. This book was released on 1996-12-10 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are one of the world's most important resources, and their protection, maintenance, and improvement is critical to the continuance of life on earth. Soil Fertility, Second Edition, offers thorough coverage of the fertility, composition, properties, and management of soils. This book carries on the tradition of excellence established by authors Henry Foth and Boyd Ellis, leading soil scientists whose previous books in this field have become multi-edition classics. The Second Edition of Soil Fertility has been significantly expanded to include more information on mineralogy, while keeping the thorough coverage of essential topics. The book presents soils as dynamic, constantly changing bodies, and relates soil fertility and management to the mineralogy of their origin. Four new chapters offer updated information on soil charge properties, ion adsorption, exchange and fixation, and soil reaction. There is also a far greater emphasis on environmental issues, reflecting the increasing importance of environmental concerns to agronomists and soil scientists today.
