Book Synopsis Soil and Fertilizer：Concepts and Practices by : 楊秋忠
Download or read book Soil and Fertilizer：Concepts and Practices written by 楊秋忠 and published by Airiti Press. This book was released on 2015-01-14 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture builds upon the integration of crops and the environment, with which its yield depends strongly on a healthy soil foundation. With that in mind, the knowledge of the soil and fertilizer is crucial to maintaining an environment with optimal nutrients, water and oxygen for crop production. Soil is one of human's precious resources, the protection and nurturing of our soil is thus an integral part of sustainable development. Effective soil management is considered not only a technology, but also an art. In practice, to make use the full potential of the land, the management strategies need to take account of the differences and characteristics of the soil, plant and climate that are unique to each geographical location. Such an approach is increasingly more important nowadays because of the increasing loss of cultivable land and need of high quality agricultural products.
Book Synopsis Soil Fertility Management in Agroecosystems by : Amitava Chatterjee
Download or read book Soil Fertility Management in Agroecosystems written by Amitava Chatterjee and published by John Wiley & Sons. This book was released on 2020-05-19 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Soil Fertility Management in Agroecosystems, Editors Amitava Chatterjee and David Clay provide a thoughtful survey of important concepts in soil fertility management. For the requirements of our future workforce, it is imperative that we evolve our understanding of soil fertility. Agronomists and soil scientists are increasingly challenged by extreme climatic conditions. Farmers are experimenting with integrating cover crops into rotations and reducing the use of chemical fertilizers. In other words, there is no such a thing as a simple fertilizer recommendation in today's agriculture. Topics covered include crop-specific nutrient management, program assessment, crop models for decision making, optimization of fertilizer use, cover crops, reducing nitrous oxide emissions, natural abundance techniques, tile-drained conditions, and soil biological fertility.
Book Synopsis Enhancing Nutrient Use Efficiency by : Kulasekaran Ramesh
Download or read book Enhancing Nutrient Use Efficiency written by Kulasekaran Ramesh and published by Nipa. This book was released on 2023-06-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrient use efficiency is a measure of how efficiently plants use the available mineral nutrients to produce economic produce. Improving nutrient use efficiency is very much essential under current scenario besides an understanding of the nutrient dynamics in soil-plant system."Enhancing nutrient use efficiency: Concepts, methods, and management interventions" is a comprehensive book which has a compilation of topics related to enhancement of nutrient use efficiency of various crops and cropping systems. Although it depends on the ability to plants to take up the nutrients from the soil, management practices have a key role to intervene the use efficiency. This book has 27 chapters written by eminent researchers in the field and addresses multifaceted approaches to enhance the nutrient use efficiency. Improving nutrient use efficiency is a prerequisite to reducing production costs in the wake of escalating cost of agricultural inputs in farming besides minimizing environmental contamination. Soil physical management is the foremost strategy to enhance the nutrient use efficiency. Hand held devices are popular among the farmers for nitrogen management in rice in several parts of the country, besides slow release nitrogenous fertilizers. Experiences from Long term fertilizer experiments and soil test crop response correlation are of immense use to understand the nutrient dynamics in soil and in turn designing practices for higher use efficiency.
Book Synopsis The Living Soil by : Kodoth Prabhakaran Nair
Download or read book The Living Soil written by Kodoth Prabhakaran Nair and published by Springer. This book was released on 2023-06-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will address the importance of the soil management concept, vis-à-vis chemical fertilizer use on soil. Historically, soil testing has been used to quantify bio availability of plant nutrients to field grown crops. However, contemporary soil tests are based on philosophies and procedures developed several decades ago without significant changes in their general approach. For a soil test to be accurate, one needs to clearly understand the physico-chemico-physiologic processes at the soil-plant root interface, and, an understanding of soils and plant root systems as polycationic systems is essential. It is this knowledge that leads to sound prescriptive soil management practices inasmuch as nutrient bioavailability vis-à-vis chemical fertilizers application is concerned, because, of all the factors that govern sustainability of crop production, the nutrient factor is the most important, yet, it is also the least resilient to effective management. The author’s research spanning over three decades in Europe, Africa and Asia, establishes the fact that precise quantification of the nutrient’s “buffer power” holds the key to a clear understanding of the plant bioavailability of some of the most important plant nutrients in crop production, such as, phosphorus, potassium and zinc. “The Nutrient Buffer Power Concept” attempts to clearly explain the bio availability of the three plant nutrients named above on the basis of the diffusion model, as that is the process by which these three important principal plant nutrients are absorbed from the soil by the plant root. Possibly, other plant nutrients which are taken up by the plant roots by the same diffusive model, would also conform to the principles of the concept. A thorough knowledge of thermodynamic principles on the part of the researcher is an absolute pre requisite for this. The book chronicles more than three decades of the professional journey of the author in Europe, Africa and Asia, understanding soil for human sustenance, and developing the revolutionary soil management concept, now globally known as, "The Nutrient Buffer Power Concept" , which has brought the author a string of international recognitions, including the nomination for the "Alternative Nobel Prize" (The Right Livelihood Award),of Sweden, and succour to millions to poor and marginal farmers across Africa, Asia and Latin America.

Book Synopsis Irrigated Soils by : David Wynne Thorne
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.

Book Synopsis Trees, Crops, and Soil Fertility by : G. Schroth
Download or read book Trees, Crops, and Soil Fertility written by G. Schroth and published by CABI. This book was released on 2003-02-19 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation. Successful agroforestry requires an understanding of the complex relationship between trees, crops and soils. This book provides a review of both economic and biophysical aspects of soil use and research in agroforestry, with an emphasis on nutrient-poor forest and savanna soils. Key topics covered include the economics of soil fertility management, cycling of water, nutrients and organic matter, soil structure, and soil biological processes. The book combines synthetic overviews of research results and a review of methods used in research.From the foreword: 2The book is written within a particular context - soil fertility development under agroforestry. At first this may seem very specific and thus limited in appeal and application. But over the last decade or so agroforestry research has been one of the most influential in developing new insights into soil biology and fertility and thus provides a very suitable framework for review of progress. Furthermore the influence of trees on soil is profound and of significance beyond agroforestry systems, so the book is likely to be of interest in the wider spheres of agriculture, forestry and ecological sciences.3 Mike Swift, TSBF, Nairobi, Kenya.
