Book Description
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.

Book Description
This book presents recently-developed crop, soil, and management practices that can be used to improve phosphorous use efficiency in agriculture. Food security highly depends on the availability of plant nutrients such as phosphorus, yet rock phosphate reserves are expected to be exhausted in the next 50–100 years. Moreover, about 80% of the phosphorous fertilizers applied to soils become unavailable to plants due to phosphorous fixation in iron and aluminum oxides in acidic soils and with carbonates in alkaline soils. As a consequence, only 10-15% of applied phosphorous is up taken by crops. Therefore, there is a need for advanced practices for improving phosphorus use efficiency.

Book Description
Extensive research on the agronomic potential and actual effectiveness of phosphate rocks (PRs) as sources of phosphorus has been carried out in Africa, Asia, Latin America and elsewhere. This publication brings together a wide range of available information on key issues regarding the use of PRs in agriculture, including world deposits; characteristics of sources; evaluation methodologies for direct application of PR (DAPR); analysis of biophysical and farming factors; development and use of decision-support systems for DAPR; soil P testing for PR application; available technologies for enhancing the agronomic effectiveness of indigenous PR sources; environmental issues; legislation guidelines; and future research priorities.

Book Description
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.
