Book excerpt: Excerpt from Simple Exercises Illustrating Some, Applications of Chemistry to Agriculture As has already been stated, there are three sources of plant food the soil, the air, and the water. From the air the plant takes m oxygen and carbonic-acid. Gas through the breathing pores of the leaves. The leaves do not use the nitrogen of the. Air. This essen tial and most expensive of plant foods is taken in by the roots of plants. Small quantities of nitrogen exist in soils in a form known as nitrates, which dissolve readily in water and enter the plant through its roots7 in company with the other plant foods. The roots of leguminous plants such as clovers, alfalfa, peas, and beans, are able also, with the aid of minute organisms known as bacteria, to use the uncombined nitrogen in the soil air.

Download or read book A Course of Practical Chemistry for Agricultural Students Vol 1 Classic Reprint written by L. F. Newman and published by Forgotten Books. This book was released on 2016-11-19 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Course of Practical Chemistry for Agricultural Students, Vol. 1 The following exercises in Practical Agricultural Chemistry are designed primarily for the use of students taking the course for the Degree in Agricultural Science at Cambridge University. Volume I is intended to cover the first year's course on the Chemistry and Physics of the Soil, while Volume II covers the second year's course on the Chemistry of Foods. The latter volume is divided into two parts: Part I dealing with such exercises in Pure Organic Chemistry as are essential for agricultural students, and is entirely qualitative, while Part II deals with quantitative estimations and technical analyses of food stuffs. This division has been considered desirable, as students who have already taken a course in Organic Chemistry will find it unnecessary to work through Part I of Volume II. Volume III deals with the special advanced Chemistry of Insecticides and Fungicides, Food preservatives, etc. It is hoped that this division into convenient booklets will make them useful to teachers. The exercises are designed to illustrate most of the essential points in Agricultural Chemistry and to require the minimum of apparatus. A Course of Practical Work was compiled by Professor T. B. Wood some years ago for the use of his classes, and this forms the foundation of a portion of the present exercises. The Sincere thanks of the authors are due to Professor Wood and the Syndics of the University Press for their permission to utilise that material.

Book excerpt: Excerpt from Chemistry in Its Application to Agriculture and Physiology Tuz former edition of this work was prepared in the form of a report on the present state of Organic Chemistry. The state of a science such as this could not be exhibited by a systematic treatise on organic compounds, but by showing that the science was so far advanced as to be useful in its practical applications.

Download or read book The Chemistry of Agriculture written by Charles W. Stoddart and published by Forgotten Books. This book was released on 2018-01-14 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Chemistry of Agriculture: For Students and Farmers There is at present need for a text on general agricultural chemistry which will cover the field briefly in a logical manner, giving only the facts, and not consisting of a dis connected series of quotations and tables from the very extended literature of the subject. The need for such a text has been particularly marked in teaching large classes of students at The Pennsylvania State College. As a con sequence the present book has been written. While it is intended primarily for students who have had previous training in Botany, Chemistry, Geology and Physics, it is sufficiently elementary to make it of value to any intelligent person. Concerning some of the statements made in the text it is well known that a difference of opinion exists among authorities, but it is deemed better to present them as facts rather than to give the various arguments or to omit them altogether.

Download or read book The Chemistry of Farm Practice Classic Reprint written by Thomas Ellison Keitt and published by Forgotten Books. This book was released on 2018-02-04 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Chemistry of Farm Practice Life, food, and raiment are directly or indirectly de pendent upon agricultural products. In the settlement of our country, land was abundant and people were few, con sequently little thought was given to the needs of the increasing numbers of succeeding generations. As the land first cultivated lost its fertility, the tide of population turned westward where unlimited areas of virgin soil awaited the herds and plowshares of the settlers. But this fresh area has been occupied, and to maintain the fertility of; those fields that are still productive and to restore those that have become exhausted is the problem now facing agriculture. The maintenance of the fertility of a productive soil demands the intelligent application of the principles of agricultural chemistry. The restoration of wornout fields is a difficult and costly undertaking. The successful farmer must reinforce his art by the application of the fundamental information derived from the study of chemistry, geology, botany, bacteriology, and entomology. Chemistry aids agriculture in many ways. By means of it, exact data are collected and the fundamental reasons for practical results are explained. Then, too, chemistry invents new or improves old methods of fertilization. The chemist analyzes soils, manures and vegetable products. The value of soil analysis to the practical farmer, perhaps formerly overrated, in more recent years has been under rated. From a soil analysis the farmer can at least learn if his soil is unusually deficient in any important element. Chemistry also protects the agriculturist from the impositions of the unscrupulous fertilizer manufacturer.

Download or read book The Future Role of Pesticides in US Agriculture written by National Research Council and published by National Academies Press. This book was released on 2000-11-02 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.
