Book excerpt: The Indian Nitrogen Assessment: Sources of Reactive Nitrogen, Environmental and Climate Effects, and Management Options and Policies provides a reference for anyone interested in Reactive N, from researchers and students, to environmental managers. Although the main processes that affect the N cycle are well known, this book is focused on the causes and effects of disruption in the N cycle, specifically in India. The book helps readers gain a precise understanding of the scale of nitrogen use, misuse, and release through various agricultural, industrial, vehicular, and other activities, also including discussions on its contribution to the pollution of water and air. Drawing upon the collective work of the Indian Nitrogen Group, this reference book helps solve the challenges associated with providing reliable estimates of nitrogen transfers within different ecosystems, also presenting the next steps that should be taken in the development of balanced, cost-effective, and feasible strategies to reduce the amount of reactive nitrogen. Identifies all significant sources of reactive nitrogen flows and their contribution to the nitrogen-cycle on a national, regional, and global level Covers nitrogen management across sectors, including the environment, food security, energy, and health Provides a single reference on reactive nitrogen in India to help in a number of activities, including the evaluation, analysis, synthesis, documentation, and communications on reactive nitrogen
Download or read book Nutrient Use in Crop Production written by Zdenko Rengel and published by CRC Press. This book was released on 2017-12-14 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you?re an agronomist, horticulturalist, plant and soil scientist, breeder, or soil microbiologist, you?ll want to read Nutrient Use in Crop Production to find everything you need to know about judicious nutrient management and maximizing nutrient utilization in the agricultural landscape. In this book, you?ll discover ways to minimize undesirable nutrient losses and techniques for preserving the environment while meeting the challenges of providing the earth?s increasing population with sufficient food, feed, and fiber to sustain life. Your existing knowledge base concerning this vital area of science will expand and grow as you become more open to the new ideas and applications contained in Nutrient Use in Crop Production. Most importantly, you?ll avoid the narrow scope found in most crop nutrition books and take a broader, more globally minded view of how to maximize nutrient use and minimize nutrient losses in the soil of agricultural systems. Specifically, you?ll find these and other areas covered: population growth, food production, and nutrient requirements managing soil fertility decline the role of nitrogen fixation in crop production delivering fertilizers through seed coatings micronutrient fertilizers the role of nutrient-efficient crops in modern agriculture Feeding the world without depleting the world?s viable soil nutrients is a monumental task--but one that can be achieved, as evidenced in the pages of Nutrient Use in Crop Production. You and your circle of students, professionals, and administrators will benefit greatly from this in-depth view of nutrient use in both developed and non-industrialized counties to give you a better sense of how to allow both the world and the world?s crops to grow.
Download or read book Fertilizer Requirements in 2015 and 2030 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2000 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a joint study involving five organisations from both the public and private sectors. The objective is to explore the future need for fertilizer required to support the Food and Agriculture Organization's (FAO) projections of agricultural commodity production for 2015 and 2030. The paper begins by briefly reviewing attempts to identify and quantify the factors influencing the growth in demand and supply for agricultural commodities. Several studies that estimate long-term fertlizer use are also reviewed, followed by a discussion of the forecasting methods and data. The results and implications conclude the paper. The study projects growth rates of between 0.7 and 1.3 per cent, depending on assumptions about nutrient efficiency over the next 35 years

Download or read book Agriculture and the Nitrogen Cycle written by Arvin Mosier and published by Island Press. This book was released on 2013-04-10 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.

Download or read book Effects of Intensive Fertilizer Use on the Human Environment written by and published by Food & Agriculture Org.. This book was released on 1978 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Fertigation written by P. Soman and published by CRC Press. This book was released on 2021-11-30 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertigation requires a thorough understanding of the science behind the technology to make it deliver the immense possibility it offers in crop production. Though the idea of fertigation existed from the times of solution culture, it did not receive the necessary attention from among plant nutritionists and agronomists when it reappeared in the context of micro irrigation. Fertilizer application in field agriculture has also not developed as a precision technology. Recommendations of the quantum of fertilizers required for a crop, at least in India are not based on current varieties of the crops, nor have they anything to do with the growth rate and developmental changes occurring while a crop is managed by the grower. Most of the fertilizer recommendations are itself very old and efforts to make them relevant to the current growing conditions, soil status, crop variety and crops reaction to the environment etc. are very limited. It is even worse when growers follow traders’ recommendations whose idea is to sell more the fertilizer they supply. Not only lower yields and very low fertilizer use efficiencies, but the deterioration of soil and water bodies are the results.
