The first soil survey in the Philippines was done by Mr. Clarence Dorsey, an American soil scientist in the province of Batangas in 1903. The Soils of the Philippines, however, is the first comprehensive summary of more than a century of soil-survey work in this country. It integrates the soil concepts of the reconnaissance soil-survey results, which commenced as early as 1934 and continued until the mid 1960s, with the semi-detailed soil surveys that continue to this day. The result is the first-ever genetic key for classifying Philippine soils at soil series level; thus, making it possible for any newcomers to the soil survey field to confidently produce their own soil map, at a more detailed map scale, to suit the project requirements. This book brings together discussions on soils and soil mapping units and up-to-date international techniques and technologies. It makes soils relevant to current political realities and national issues. As soil survey moves from a reductionist agricultural-development planning tool to a more holistic and integrated approach, to enable us to understand our dynamic and complex environment, The Soils of the Philippines will be the only source of authoritative and updated data on soil resources for macro-level resource management planning for decades to come. With a vanishing breed of experienced soil surveyors, not only in the Philippines but also worldwide, it may remain the only book on Philippine soils for the next hundred years or more. Since soils follow a geological and not a human time frame, the contents of this volume will stay relevant for soil surveyors even in a fast changing world. As the country leaps from an agricultural economy towards modernization and a more diversified economic base, some of the soil series in the Philippines, for example the Guadalupe series underlying the skyscrapers of Makati City, are becoming extinct as a result of urban development. Therefore, this book serves as the repository for the soils that we possess, the soils that have been lost through decades of urbanization while, at the same time, it creates a soil classification system for the soils we are yet to discover.

After green revolution was launched in India, substantial increase in the production of food-grains was achieved through the use of improved crop varieties and higher levels of inputs like fertilizers water and plant protection chemicals. This made the revolution possible but it has limitations of higher costs and of causing damage to the environment specially when inputs are not used efficiently and judiciously. A decline of yields are being reported from the green revolution belts of India, in spite of liberal application of fertilizers and other inputs. The environmental problems are now becoming real problems of the developing countries as well as developing world. This disturbing trend is attributed to soil degradation, multi nutrient deficiencies and pest and diseases build up. The use of chemical inputs increases yields for a limited period, but without good management there is rapid deterioration of land and water resources. Inefficient use of fertilizers results in polluting the environment, in addition to wastage of scarce resource. It is therefore, imperative to conserve and utilize optimally the available production resources like land, water and genetic diversity and to efficiently manage the agricultural inputs for sustaining high crop productivity on a long term basis, with minimum damage to ecological and socio-economic environment. In this context, publication of a reference book is timely and appropriate. As the scientists, students, planners, administrators and extensionists recognize the importance of environmental problems related to agriculture, but they need ready reference to learn more about the problems, plan research agenda and develop strategies to tackle the problems. Hence, an attempt has been made to compile the information and presents in a readable form in this book. The book not only covers the effect of excessive use of chemical inputs on environment but also the effect of other human activities on agricultural production. It is sure that the book will be of immense use of post-graduate students and research workers in agricultural and environmental sciences, extension workers, progressive farmers, officials of the department of agriculture, environment and pollution control board administrators, planners and policy makers and the technical staff working in the agricultural input industry.

Rice in Deep Water gives a detailed description of the complex agroecosystem and the growth and development of deepwater rice, a fascinating crop grown by subsistence farmers in the deltas and floodplains of Asia and West Africa flooding to depths of 2-3 metres. An account of the various cultural methods and socioeconomic conditions of the farmers is given, current research efforts to increase productivity discussed and research priorities suggested. The book is designed and profusely illustrated so as to emphasize the complexity and dynamic nature of plant and environment, an aspect so often poorly appreciated and misunderstood.

Soils comprise the largest pool of terrestrial carbon and therefore are an important component of carbon storage in the biosphere-atmosphere system. Structure and Organic Matter Storage in Agricultural Soils explores the mechanisms and processes involved in the storage and sequestration of carbon in soils. Focusing on agricultural soils - from tropical to semi-arid types - this new book provides an in-depth look at structure, aggregation, and organic matter retention in world soils. The first two sections of the book introduce readers to the basic issues and scientific concepts, including soil structure, underlying mechanisms and processes, and the importance of agroecosystems as carbon regulators. The third section provides detailed discussions of soil aggregation and organic matter storage under various climates, soil types, and soil management practices. The fourth section addresses current strategies for enhancing organic matter storage in soil, modelling techniques, and measurement methods. Throughout the book, the importance of the soil structure-organic matter storage relationship is emphasized. Anyone involved in soil science, agriculture, agronomy, plant science, or greenhouse gas and global change studies should understand this relationship. Structure and Organic Matter Storage in Agricultural Soils provides an ideal source of information not only on the soil structure-storage relationship itself, but also on key research efforts and direct applications related to the storage of organic matter in agricultural soils.
