Download or read book Guidelines for Soil Description written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2006 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.

Download or read book Soils Plant Growth and Crop Production Volume III written by Willy H. Verheye and published by EOLSS Publications. This book was released on 2010-11-30 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils, Plant Growth and Crop Production is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. Plants, and crops in particular, grow and develop through the uptake of water and nutrients by the root system in soils and their transformation into biomass through processes governed by photosynthesis. The quality and amount of products harvested from this biomass depend largely on the intrinsic properties of the soil, i.e. the moisture and nutrients made available for uptake by the roots. These volumes describe in a synthetic form the impact of the most important soil properties on general agronomy, crop production, cultivation methods, and yields, including the specific management aspects which take away some production constraints. Changes in general agronomy as a result of plant breeding, climatic change and competition between newly introduced crops are discussed. The three volumes with contributions from distinguished experts in the field discusses about soils, plant growth and crop production in several related topics. These volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Download or read book Developments in Soil Classification Land Use Planning and Policy Implications written by Shabbir A. Shahid and published by Springer Science & Business Media. This book was released on 2013-02-15 with total page 875 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world’s population continues to expand, maintaining and indeed increasing agricultural productivity is more important than ever, though it is also more difficult than ever in the face of changing weather patterns that in some cases are leading to aridity and desertification. The absence of scientific soil inventories, especially in arid areas, leads to mistaken decisions about soil use that, in the end, reduce a region’s capacity to feed its population, or to guarantee a clean water supply. Greater efficiency in soil use is possible when these resources are properly classified using international standards. Focusing on arid regions, this volume details soil classification from many countries. It is only once this information is properly assimilated by policymakers it becomes a foundation for informed decisions in land use planning for rational and sustainable uses.

Download or read book The Soils of Bulgaria written by Toma Shishkov and published by Springer. This book was released on 2014-07-08 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Soils of Bulgaria offers a comprehensive analysis of the characteristics of soils and concepts on their magnitude. The purpose of the book is to introduce readers to the soil problematic and ecology in Bulgaria. The volume is divided into 3 parts. The first includes historical facts on soil research in Bulgaria, as well as general conditions and factors of soil formation, while the second applies an original pedological approach. The book’s third part focuses on essential information concerning land use/cover in Bulgaria. Each of the 13 chapters deals more specifically with fundamental chemical and physical soil properties, concepts of soil evolution, old and modern processes, geographic distribution, climatic conditions, topography, parent materials, plant associations, morphology and the relationship with different classification systems. The interactions between soil status and management are also highlighted. The use of the latest, statistically significant data ensures precise conclusions. The book also includes a large number of charts and new illustrations. The Soils of Bulgaria is crucial reading material for anyone interested in soil management and agriculture in Easter Europe, from students to policy makers and is also of particular interest for researchers in the field.

Download or read book Irrigated Soils written by David Wynne Thorne and published by Daya Books. This book was released on 2004-09 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most Of The Arable Soils Of Humid Temperate Areas Are Now Employed For Crop Production. With An Ever-Increasing Population, The World Is Again Rapidly Turning To The Further Development Of Irrigation In The Semi-Arid And Arid Lands Which Comprise Over Half Of The Earth S Land Surface. Today More Than Half Of The World S Population Is Dependent On Food Produced Under Irrigation. Authors Have Kept Constantly In Mind The Idea Of Integrated Plants Which Will Give Maximum Production On Irrigated Farms. In This Approach, Discussion Of Such Topics As Soil Water Relations, Salt, Alkali, Soil Physical Properties, Organic Matter, Crop Rotations, Fertilizers, And Irrigation Practice Have Been Directed Toward Recognizing The Solving Practical Farm Problems. The Emphasis On Farm Planning Throughout The Book Has Been Brought To A Final Conclusion With A New Chapter On Planning The Irrigated Farm. The Recent Rapid Expansion Of Irrigation In Humid Regions At First Thought Seems To Justify Special Treatment. But Further Consideration Indicates That The Same Fundamental Principles Are Involved Wherever Irrigation Is Practiced, Whether In Arid Or Humid Areas. The Salt Problem Seldom Occurs In Humid Regions And Liming Must Be Practiced, But Still The Underlying Principles Of Irrigation Agriculture Are The Same. In Preparing The Manuscript The Authors Have Sought To Emphasize Fundamental Principles That Underlie Soil Management Practices. Emphasis Is On Basic Principles Rather Than On Field Practices. The General Approach Is To Present First The Fundamental Principles And Second The Applications Of The Principles In Solving Individual Problems. The Authors Sought To Bring Together Viewpoints From Different Fields Of Investigation And To Harmonize Them Into An Integrated Presentation. For Example, In Soil Moisture Studies, Soil Scientists Have Customarily Dealt In Terms Of Physical Stresses Exerted On Moisture By Capillary Pull And Adsorption By Soil Particles; Plant Physiologists Have Been Concerned With Osmotic Stress Value Resulting From Salts Dissolved In Soil Or Culture Solutions. In Irrigation Agriculture, Both Concepts Are Vitally Important And Are Presented As A Unified Principle That Must Be Evaluated In Estimating The Water Relations Of Plants In Irrigated Soils. This Book Will Be Useful In College Dealing With Irrigation And The Management Of Irrigated Soils, But Also As A Reference Guide To Those Giving Technical Advice To Farmers On The Management Of Irrigated Soils.
