Download or read book Optimizing The Soil Physical Environment Toward Greater Crop Yields written by Daniel Hillel and published by Elsevier. This book was released on 2012-12-02 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimizing the Soil Physical Environment Toward Greater Crop Yields contains the proceedings of an invitational panel convened during the International Symposium on Soil-Water Physics and Technology held at The Hebrew University Faculty of Agriculture in Rehovot, Israel, August 29 to September 5, 1971. Organized into 13 chapters, this book begins with a discussion on the criteria for determining the aims and direction of research in soil physics and technology. Some chapters deal with the transformation and fluxes of energy and matter in the field, particularly water, soil temperature, soil structure, soil salinity, radiation climate, and nutrient supply and uptake. The book also explores the methods of measuring, managing, and modifying the crop production system to greater agricultural advantage. This book will reflect not only what is known, but also what is missing in the incomplete conception of this environment.

Download or read book Fundamentals of Soil Science written by H. D. Foth and published by John Wiley & Sons. This book was released on 1978 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: This major revision of a bestselling text shows that soil is three-dimensional and dynamic. This concept is developed in the first two chapters and is built on throughout the book. Chapters 3 through 7 explore soil physical properties and water, with expanded coverage of tillage and traffic and an increased emphasis on water and wind erosion processes. Chapters 8 through 11 discuss the biological aspects of soils as well as their mineralogical and chemical properties. In Chapters 12 through 15, the general area of soil fertility and fertilizer use is covered. Other chapters examine soil genesis, taxonomy, geography, land use and soil survey, and land use interpretations. Finally in chapter 20, the importance of nonagronomic factors in the food population problem are discussed. Both English and metric units are used for crop yields, new figures and tables are included, summary statements are given at the end of the more difficult sections and at the end of each chapter, and non-agricultural examples and several computer applications are provided for reference.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Productive Soils: The Fundamentals of Successful Soil Management and Profitable Crop Production; 235 Illustrations in the Text This course of study in the complete edition is designed to give it wide adaptation, to wit: (a) It may serve as a farmers' ready reference, or as a practical guide in successful soil management. (b) In college short courses, and normals, the whole course as it is planned may be given. The object of each student should be to master the fundamentals. (c) In college long courses, this text in the hand of the first- or second-year student may supply him with the fundamentals, leaving the lecture hour free to the instructor for elaboration, for application of facts and principles to local conditions, and for the presentation and discussion of experimental and research data. The subject of Soil Management and Crop Production is truly large enough and of sufficient importance to be given a place in every agricultural curriculum. This subject should precede or may be given at the same time as the allied subject, Farm Crops. The latter subject could then be made a study, not so much of soils in relation to growing the crops, but rather of crop characteristics, crop importance, types, varieties, judging of grains, seed production, special cultural methods, harvesting, and care of crops and grains. At the close of each chapter suggestions are offered for demonstrations, laboratory exercises, and for home experiments and projects. Many questions and practical problems are also given. The author wishes to express his appreciation to Prof. E. Truog of the Department of Soils, and to Prof. J. A. James of the Department of Agricultural Education, University of Wisconsin, for careful reading and approval of the manuscript; to Prof. E. R. Jones, University of Wisconsin, for verifying the chapters on water relations and drainage; to Prof. C. F. Marbut, in charge of soil survey, Bureau of Soils, United States Department of Agriculture, for valuable suggestions concerning soil types and for approval of that part of Chapter II relating to that subject.

Download or read book Soil Physical Environment and Plant Growth written by Pradeep K Sharma and published by Springer Nature. This book was released on 2023-08-28 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook on the applied aspects of soil physics covers introduction to soil physical properties and processes, and their evaluation and management in relation to plant growth. It distinguishes physical properties that directly influence plant growth from those that indirectly affect agricultural productivity. Chapters are also devoted to the concept of soil health and the role of soil physics on preservation of soil health and environmental quality. As such, this book fills a unique knowledge gap for agriculture and agronomy students, course directors as well as field professionals.
Download or read book Soils Land and Life written by S. W. Buol and published by Prentice Hall. This book was released on 2008 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unbiased in approach, this book discusses the physical and chemical land and soil requirements needed to produce food and how economic, social, and political environments influence agricultural productivity. Presenting an array of soil and land properties and farming methods-ranging from slash and burn to highly technical practices-the author draws on his 40 years of worldwide experience to give readers a glimpse at the historical developments, natural resource concerns, and farming practices impacting human food production today.Presents the basics of how soils and land function and examines the impact of water, temperature and chemical elements on food production using minimal scientific terminology. Moves beyond explaining the physical and chemical requirements of human food production to encompass the economic, social and political factors that impact farming practices and overall productivity. Covers current farming methods being used in other countries, from the recent advances in farming on the poorest soils to the slash and burn farming in tropical jungles. Presents historical data to show how modern practices have reduced the cost of food and the amount of land needed to feed a growing population. Provides a strong foundation and makes later chapters on leaching, ground water contamination, floods and erosion easier to understand. Emphasizes the delicate balance of essential elements from the air and in the soil and presents the basic physical and chemical dynamics of the human food chain.Those looking for an easy to understand introduction to how and why various types of soil and land are used for human food production.

Book excerpt: Excerpt from Productive Soils: The Fundamentals of Successful Soil Management and Profitable Crop Production; 235 Illustrations in the d104 The chief concern of the human race is its physical needs. Its greatest needs - food and clothing, depend entirely upon the soil which is intimately associated with life. Myriads Of plants and animals have lived upon the earth for ages and ages because soil exists. Every nation is deeply interested in the soil and its crops. Shall we grow more wheat to meet the demands Of our increasing population, or shall we import it? Shall we meet the demand for more cotton, or shall it be grown elsewhere? Are our working people to have meat on their tables in the years to come, or will the price of meat be. Beyond their means? These questions can be answered only by the soil.
