Download or read book Changes in Paddy Soil Fertility in Tropical Asia under Green Revolution written by Junta Yanai and published by Springer Nature. This book was released on 2022-06-20 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the effect of the Green Revolution (GR) on long-term changes in the fertility status of paddy soils in tropical Asia. While information on long-term changes in soil fertility status are rather limited due to difficulties in obtaining past data or samples for comparison, this investigation on temporal changes in soil fertility is possible by comparing fertility status in the 2010s, which the authors examined recently, with those from the 1960s, when GR was initiated, which was reported by Kawaguchi & Kyuma (1977). More than 220 paddy soils collected from Thailand, the Philippines, Malaysia, Bangladesh, and Indonesia were analyzed for their physicochemical properties as well as total and available fractions of plant macro- and micro- essential elements, and their temporal changes were examined in addition to their spatial variation in each country. The most significant change was a drastic increase of available phosphorus in soils, possibly due to fertilization after the GR. Changes in organic matter, pH, and other nutrients were relatively small. A considerable decrease in the content of some micronutrients was also observed. Long-term studies on soil fertility status in the past and present will be useful to establish soil/fertilizer management for sustainable rice production in the future. This book is an essential reading for soil scientists, agricultural scientists, environmental scientists, as well as policymakers and nongovernmental officers such as FAO.

This book was released on 2012-12-06 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: China contributes a large part to rice production, one of the most important crops in the world. It is estimated that in China rice constitutes about half of the total food production, covering an area of about 30 % of \08 hectares of cultivated land of the whole country. Owing to the peculiar water regime, paddy soils possess quite different properties physically, chemically and biologically as compared with those of upland soils. Such properties have a conspicuous effect on fertility and management practice of paddy field. For the purpose of summing up the past work and opening up new prospects, a "Symposium on Paddy Soils" was organized under the auspices of Academia Sinica, held on October 19-24, 1980 in Nanjing, which was followed by a seven-day paddy soil excursion in the lower Changjiang Delta. In addition to 120 Chinese soil scientists, 56 guests coming from America, Asia, Europe and Oceania attended the symposium on invitation. A total of 110 papers were presented either orally or by poster. All these are collected and published in the present proceedings which we hope may be helpful to the scientific exchanges between soil scientists of China and other countries.

Available in PDF, EPUB and Kindle. Book excerpt: Soil Genesis That Studies The Evolution Of Soils And The Changes Taking Place In Soil Bodies Has Received Increasing Interest And Attention In The Twentieth Century, And This Yet Continues. Despite The Fact That The Indian Soil Scientists Have Made Much Investigation Into The Subject Of Soil Genesis, Classification, Survey And Evaluation, There Are Very Few Books That Provide Ample Instructional Material Relevant To Situation In India. The Present Book Is Primarily Focused On The Study Of Geological Conditions Of India. Briefly Outlining The Fundamental Concepts Of Soil Genesis And Acquainting The Readers With Rich Minerals Present Under The Soil, The Book Provides A Detailed Study Of The Factors And Processes Of Soil Formation, Including Description And Interpretation Of The Soil Profile And Patterns Of Soils Occurring On The Surface Of The Earth. Furthermore, It Lays Down The Purpose And The Historical As Well As Modern Basis Of Classification Of Soils In Different Countries Across The World. It Particularly Provides An In-Depth Study Of Soils Prevalent In The Varied States Of India In Addition To The Assessment Of Productivity Of Bench Mark Soils Of The Country. The Book Also Covers Significant Areas Like Remote Sensing, Soil Survey, Land Use, Land Capability Classification, Land Irrigability Classification, Land Evaluation, Land Use Planning And Cartography. Considerable Authentic Information Has Been Drawn From The Works Of Indian Soil Scientists In These Disciplines Which Has Necessarily Added To The Value Of The Book.Designed As A Textbook, Its Approach To The Subject Is Reader-Friendly. Its Simple Language And Lucid Style Make It Accessible Even To Average Students. It Is Hoped That The Book Will Prove Immensely Useful And Informative To Students And Teachers Of Geology As Well As Soil Surveyors.

This book was released on 2018-05-17 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume introduces dynamic approaches to the study of Southeast Asia’s environmental diversity from different disciplinary perspectives at the interface between the natural and social sciences. It brings together research on the region’s environmental resource use and shared ecological challenges in the context of present day globalization to offer insights for possible future directions. The book introduces unique approaches to the study of Southeast Asia’s environmental changes and resource management under the influence of intensifying economic change in the region. It also examines the slow erosion of Southeast Asia’s rich environment and addresses serious issues such as the decrease in biodiversity and tropical forests, and the degradation of peat lands. At the same time, it discusses the social issues that are tied to energy-dependent growth and have intensified over the last two decades. It also analyzes the new roadmaps being created to protect, conserve, and manage the environment. By investigating the many ecological issues surrounding us, the volume brings to light the constant struggles we face while trying to develop a more inclusive and equitable approach to natural resources governance. This volume is relevant for students, academics and researchers who have an interest in the Southeast Asian environment and the way in which we use and interact with it.
