Agriculture is the main occupation in India and about 75% of its population depends directly or indirectly on agriculture for their livelihood. It is the dominant sector that contributes 18% of the gross domestic product. Thus, agriculture is the foundation of the Indian economy. The maximum share of Indian exports is also from the agriculture sector. As the population of the country is increasing trem- dously, approximately at the rate of 19 million every year over the existing popu- tion of more than 1 billion (approximately 1. 18 billion), the food grain production must necessarily be increased. This can be done by increasing crop production to match the population growth rate of 2. 2% per annum, which is expected to stabilize at 1. 53 billion around 2050. There is no doubt that the Green Revolution in India during the late 1960s brought self-sufficiency in food grain production, mainly through the increase in rice and wheat crop yields – the two main crops of the country which play an important role from food security point of view. However, the excessive use of fertilizers and pesticides, and the neglect of organic manures for these crops, has resulted in the deterioration of physical, chemical and biological health of the ri- and wheat-growing soils. Owing to the deterioration of the health of these soils, the productivity of the rice–wheat cropping system has now either got reduced or in some places has become constant for the last decade.

Sustainable agriculture productivity depends on successful maintenance of soil fertility. Among the 16 essential elements required by the plants carbon, hydrogen and oxygen are taken from air and water which account for about 96 per cent of the plant composition while the rest account for about 4 per cent called mineral nutrients. These are absorbed by the plants from soil. They play structural and functional role in the plants, besides there are some elements which play beneficial role in the plants. The mineral elements interact with soil organic matter, clay minerals, soil microorganisms and other associated mineral elements. These interactions determine their availability and dynamics in the soil. Understanding of the dynamics of plant nutrients in the soil will provide scientific basis for efficient nutrient management. Soil organic matter not only provides the nutrients required by the crop but also improve the biological and physical properties of the soil. Attempt has also made to provide information on production and management of organic manures, biofertilizers, integrated nutrient management in cropping systems and nutrient management in problematic soils.

This book conceptualizes a revolutionary idea based on a mechanistic-mathematical model in which the “Buffer Power” of the principal and problematic nutrients like phosphorus, potassium and zinc is quantified. This is achieved by using either a very sophisticated technique, electro-ultra-filtration, or a simple adsorption-desorption equilibrium technique, and by integrating the “Buffer Power” of the nutrient in question into the computations, accurate fertilizer recommendations are made. This technique was field tested across Europe, (Germany and Belgium), Africa (The Republic of Cameroon), and Asia (both Central Asia- Turkey and South Asia-India), during a period of three decades in test crops, such as, summer rye (Secale cereale), maize (Zea mays), wheat (Triticum aestivum), white clover (Trifolium repens), a highly nutritious and palatable fodder crop for Africa, black pepper (Piper nigrum) and cardamom (Elettaria cardamomum). Remarkable precision in predictability of plant uptake of phosphorus, potassium and zinc was obtained employing the technique. “The Nutrient Buffer Power Concept” project was shortlisted for the very prestigious U.S. $1 Million Rolex Awards For Enterprise of The Rolex Foundation, Geneva, Switzerland, for its outstanding originality and quality from more than 3500 nominations worldwide and is the only project chosen for this very coveted distinction from the Asian continent.

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.

The cropping system is one of the important components of sustainable agriculture, since it provides more efficient nutrient cycling. As such, balanced fertilization must be based on the concept of sustainable crop production. Feeding the rapidly growing world population using environmentally sustainable production systems is a major challenge, especially in developing countries. A number of studies have highlighted the fact that degradation of the world's cultivated soils is largely responsible for low and plateauing yields. Soil is lost rapidly but only formed over millennia, and this represents the greatest global threat to nutrient dynamics in agriculture. This means that nutrient management is essential to provide food and nutritional security for current and future generations. Nutrient dynamics and soil sustainability imply the maintenance of the desired ecological balance, the enhancement and preservation of soil functions, and the protection of biodiversity above and below ground. Understanding the role of nutrient management as a tool for soil sustainability and nutritional security requires a holistic approach to a wide range of soil parameters (biological, physical, and chemical) to assess the soil functions and nutrient dynamics of a crop management system within the desired timescale. Further, best nutrient management approaches are important to advance soil sustainability and food and nutritional security without compromising the soil quality and productive potential. Sustainable management practices must allow environmentally and economically sustainable yields and restore soil health and sustainability. This book presents soil management approaches that can provide a wide range of benefits, including improved fertility, with a focus on the importance of nutrient dynamics. Discussing the broad impacts of nutrients cycling on the sustainability of soil and the cropping systems that it supports, it also addresses nutrient application to allow environmentally and economically sustainable agroecosystems that restore soil health. Arguing that balanced fertilization must be based on the concept of INM for a cropping system rather than a crop, it provides a roadmap to nutrient management for sustainability. This richly illustrated book features tables, figures and photographs and includes extensive up-to-date references, making it a valuable resource for policymakers and researchers, as well as undergraduate and graduate students of Soil Science, Agronomy, Ecology and Environmental Sciences.

With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.
