Nutrient Management for Sustainable Crop Production in Asia by A. E. Johnston,John Keith Syers Pdf
During the past 30 years, crop yields, particularly of rice, have been greatly increased in many Asian countries by advances in plant breeding and by the application of nitrogenous and phosphatic fertilizers. This has become known as the "Green Revolution", which has been a major factor underpinning the rapid growth of Asian economies, providing a cheap, indigenous food supply. However, while human populations continue to increase, in many cases yields are no longer being sustained, due to a reduction in soil quality. Thus, food security in Asia has again become a source of concern. This book is the result of an international conference held in Bali in December 1996, initiated by The World Phosphate Institute (IMPHOS) to discuss the action which must be taken to reverse soil degradation and improve nutrient levels. It includes papers and working group reports on nutrient management and balance, the potential of different phosphate sources, rock phosphate efficiency in acid upland soils, current usage and future requirements for fertilizers, sustainability and the environment, and policy and pricing. Finally, there is a summary and conference resolution. Contributors to the book come from Europe, USA, Australia and many Asian countries. It is essential reading for soil scientists and agronomists concerned with agriculture in Asia and will also be of interest to environmentalists, ecologists and economists concerned with sustainable natural resource management.
Sustainable Agriculture Reviews 32 by Eric Lichtfouse Pdf
This book summarise advanced knowledge and methods to recycle waste and fertilise soils in agriculture. In the near future, waste recycling will no longer be an option because natural resources become rare and costly, urbanisation is blooming and population is growing. In theory, most waste could be recycled. In practice, most waste is wasted. Remarkable aspects include the concepts of waste hierarchy eco-houses in smart cities, microbes and fungi for plant nutrition, and benefits of legume cultivation, biochar application and agropastoralism.
Biological Nitrogen Fixation for Sustainable Agriculture by J.K. Ladha,T. George,C. Bohlool Pdf
Chemical fertilizers have had a significant impact on food production in the recent past, and are today an indispensable part of modern agriculture. On the other hand, the oil crisis of the 1970s and the current Middle East problems are constant reminders of the vulnerability of our fossil fuel dependent agriculture. There are vast areas of the developing world where N fertilizers are neither available nor affordable and, in most of these countries, balance of payment problems have resulted in the removal of N fertilizer subsidies. The external costs of environmental degradation and human health far exceed economic concerns. Input efficiency of N fertilizer is one of the lowest and, in turn, contributes substantially to environmental pollution. Nitrate in ground and surface waters and the threat to the stability of the ozone layer from gaseous oxides of nitrogen are major health and environmental concerns. The removal of large quantities of crop produce from the land also depletes soil of its native N reserves. Another concern is the decline in crop yields under continuous use of N fertilizers. These economic, environmental and production considerations dictate that biological alternatives which can augment, and in some cases replace, N fertilizers must be exploited. Long-term sustainability of agricultural systems must rely on the use and effective management of internal resources. The process of biological nitrogen fixation offers and economically attractive and ecologically sound means of reducing external nitrogen input and improving the quality and quantity of internal resources. In this book, we outline sustainability issues that dictate an increased use of biological nitrogen fixation and the constraints on its optimal use in agriculture.
The book deals with agroecological aspects of nutrients essential to crop production. A new concept termed 'AGROSPHERE' has been introduced in the book. A brief description about agrosphere, its expanse, contrasting features and interactions with other ecospheres, global nutrient dynamics and food production trends within various agro ecosystems fo
Plant Nutrient Acquisition by N. Ae,J. Arihara,K. Okada,A. Srinivasan Pdf
New research reveals that plants actively acquire nutrients; the acquisition process is not a passive one in which plants simply wait for dissolved nutrients to come closer to their roots. In fact plants play a far more active role than once was understood to be possible in nutrient acquisition and in adaptation to problem soils. This book presents an excellent overview and summary of new concepts of plant nutrient acquisition mechanisms, and sets forth their practical implications in crop production. The scope is wide ranging, from biochemical, molecular, and genetic analysis of nutrient acquisition to global nutritional problems. Especially noteworthy are the sections on the cell apoplast, phosphorus-solubilizing organisms, and direct uptake of macro-organic molecules. With contributions by leading scientists worldwide, the book provides an invaluable resource for researchers in plant and environmental sciences and in agronomy and other branches of agriculture.
Phosphorus in Agriculture: 100 % Zero by Ewald Schnug,Luit J. De Kok Pdf
The title ‘Phosphorus in Agriculture: 100 % Zero’ is synonymous for make-or-break. And it stands up to the promise. This book sends an important message as it delivers background information, intrinsic hypotheses, validation approaches and legal frameworks, all for balanced phosphorus fertilization in agriculture. This implies firstly that the phosphorus requirement of crop is fully satisfied by applying exclusively fertilizers which contain the nutrient in completely available form. Secondly, environmental demands through eutrophication and hazardous contaminants must not be compromised. The book identifies equally knowledge gaps and deficits in the transformation and implementation of research into practice. Bottom line is that research delivers the tools for a sustainable phosphorus management while legal frameworks are insufficient.
The Rice-Wheat Cropping System of South Asia by Palit Kataki,Suresh Chandra Babu Pdf
The lives of more than a billion people depend on the answer! This valuable book surveys the problems of the rice-wheat cropping system practiced on the Indo-Gangetic Plain (IGP). Introduced at the time of the Green Revolution, it transformed agriculture and produced thirty years of bumper crops. The Rice-Wheat Cropping System of South Asia: Efficient Production Management offers scientific analysis of the aftereffects of this intense cropping. The Rice-Wheat Cropping System of South Asia: Efficient Production Management focuses on the questions of soil depletion, pest infestation, and soil alkalinity as elements of declining productivity. Along with clear charts, maps, and graphs, it provides practical suggestions for improving and maintaining the productivity of this irreplaceable farmland. The Rice-Wheat Cropping System of South Asia looks at the problems that have arisen for both the rice and wheat phases, including: depletion of micronutrients degradation of major nutrients from unbalanced fertilization practices infestations of nematodes increasing soil alkalinity as a result of irrigation It also suggests solutions for maintaining productivity, including: integrated pest management sustainable agriculture micronutrient fertilizers This informative book and its companion volume, The Rice-Wheat Cropping System of South Asia: Trends, Constraints, Productivity and Policy, are essential planning tools for agronomists, policymakers, and agroeconomists. It is also a useful reference for anyone interested in the problems of famine and intensive cropping not only in South Asia but in the world.
