Excerpt from Effect of Crops and Fertilizer on Soil Nitrogen, Carbon, and Water Content, and on Succeeding Wheat Yields and Quality Evans, and Miles (4) studied the effect of 30 or more years of cropping on N and C content of soil at three locations in the Great Plains. Three years of alfalfa or grass in a 6-year rota tion reduced the loss of soil N and C compared to small grain cropping, but neither alfalfa nor grass maintained these elements at their orig inal level.

Nitrogen fertilizers are the inescapable necessity to enhance agricultural production and to sustain food security. However, their inefficient use accrues from inherent limitations of the crop plants as well as the manner in which N fertilizers are formulated, applied and managed. Excessive accumulation of N in the environment leads to soil acidification, pollution of groundwater and eutrophication of surface water, posing a public health problem as well as ecosystem imbalance. Moreover, the ozone layer depletion and greenhouse effects of NOx gases have global implications. Agricultural Nitrogen Use: Environmental Implications provides a comprehensive, interdisciplinary description of problems related to the efficient use of nitrogen in agriculture, in the overall context of the nitrogen cycle, its environmental and human health implications, as well as various approaches to improve N use efficiency. The book is presented in six sections: N Use, Flows and Cycling in Agricultural Systems; N Use Efficiency in Crop Ecosystems; Management Options and Strategies for Enhancing N Use Efficiency; Plant Physiological and Molecular Aspects of Enhancing N Use Efficiency; Role of Legumes and Biofertilizers in Agricultural N Economy; and Environmental and Human Health Implications.

A number of countries in Europe and North America have been using fertilizers heavily for a number of years and particulary since 1945. This high level of fertilizer applications is essential to supply the necessary food for increasing populations and to meet higher demands for animal and plant products. Effects of fertilizer use on the environment should show first in countries where fertilizers have been used intensively for some time and where consumption is steadily rising. It is the experience gained in such countries which is being discussed below with a view to assessing the impact of fertilizers on the human environment, including the development of methods for recognizing and minimizing any undersirable consequences which may be produced. It should be realized that high densities of human population combined with intensive crop and livestock production have led to the production of organic wastes at a rate too high for natural processes to convert it in ecologically safe compounds. Therefore both direct and indirect effects of intensive fertilizer use have been reviewed.

Nitrogen fertilizers are necessary to enhance agricultural production and to sustain food security. However, their inefficient use accrues from inherent limitations of the crop plants as well as the manner in which N fertilizers are formulated, applied and managed. The main aim of the book is to assess the various aspects of the fate of fertilizer N in context of the overall N inputs to agricultural systems, with a view to enhance the efficiency of nitrogen use and reduce the negative impacts on environment. The cross cutting issues relate to improvement in nitrogen use by emerging technologies (genetic enhancement, QTL mapping), meeting N needs by understanding its interactions with other nutrients, and mitigation of nitrogen losses caused by environmental factors and management practices. Nitrogen Use Efficiency in Plants develops links between basic and applied research and practical crop production by addressing a wide range of topics relating to nitrogen use efficiency, and to plant and crop responses to applications of nitrogen via fertilizers, including nitrogen acquisition and reduction, molecular approaches, nitrate induction and signaling; and nitrogen use under abiotic stresses. Nitrogen Use Efficiency in Plants is an invaluable classroom aid for academics working in plant physiology, biochemistry, biotechnology, molecular breeding and agronomy, and an essential professional resource for researchers working in plant and crop systems as it provides a comprehensive, interdisciplinary description of problems related to the efficient use of nitrogen in agriculture.

Emphasis in agricultural production has shifted from mere quantity to quality products. Practical experience and scientific investigations have shown that, of the various culture measures, balanced fertilization above all exerts a considerable influence on the quality of agricultural products. Simply adding more of what the crop has already absorbed to capacity is unproductive, expensive, wasteful and damaging to the environment. Therefore, balanced crop nutrition increases crop quality, safeguards natural resources and brings benefit to the farmer. Otherwise rapid population growth and severe urbanization will exhaust our natural resources.

Nitrogen fertilizer broadcast in November or December on widely different soils at seven locations in Alabama, Georgia, and Mississippi during 1955-59 was only 49 percent as effective as nitrogen fertilizer applied the following spring when measured by corn yields. In terms of nitrogen recovered, the relative effectiveness was 62 percent. There were no consistent differences among the five nitrogen sources applied in the fall as measured by corn yields, but nitrogen recovery tended to be lower from urea than from the other sources. Considerable residual effects of spring-applied nitrogen were found over a period of 16 months based on both yield and nitrogen uptake by the crops. Average uptakes of 25 and 34 pounds per acre of additional nitrogen were made by the second and third crops, respectively, from the 200-pound original application. This residual nitrogen produced average yield increases of 1,600 pounds of dry forage and 19 bushels of corn per acre. These results emphasize the economic importance of residual nitrogen and the need for soil test procedures for its estimation.

Nitrogen (N) is potentially one of the most complex elements on the Earth. It is necessary for all biological activity, but creates negative impacts on water and air quality. There is a balancing act between deficiency and surplus and the forms of N available further complicate our understanding of the dynamics. Biological fixation provides some plants with N supply while others are totally dependent upon N being available in the soil profile for the roots to extract. Nevertheless, the demand for N will increase because the human population with its increasing growth requires more protein and thus more N. Understanding the global N cycle is imperative to meeting current and future nitrogen demands while decreasing environmental impacts. This book discusses availability, production, and recycling of N in air, water, plants, and soils. It features information on N impacts to soil and water quality, management of N in agroecosystems, and techniques to maximize the use efficiency while minimizing the risks of leakage of reactive N into the environment. This volume in the Advances in Soil Science series is specifically devoted to availability, production, and recycling of N with impact on climate change and water quality, and management of N in agroecosystems in the context of maximizing the use efficiency and minimizing the risks of leakage of reactive N (NO-3, N¬2O) into the environment.

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.
