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.

According to the African Development Bank, agricultural activities comprise around 15 percent of the continent’s gross domestic product (GDP) and agricultural employment represents around 58 percent of total employment in Sub-Saharan Africa. The region’s population is expected to double to 2 billion people by 2050. Along with expected income growth, the population increase will lead to a substantial rise in food requirements. To meet food demand, FAO estimates that agricultural production would have to increase 112 percent between 2013 and 2050. Meeting this demand will not be easy, as agricultural productivity in SSA remains low and shows slow growth. The vast majority of African smallholder farmers produce low-yield food crops using a minimal set of inputs. Inadequate access to improved inputs such as fertilizers presents a major constraint for smallholders. In the region, more nutrients are removed with harvested crops than are applied with fertilizer or manure, resulting in unsustainable soil nutrient depletion. Improved fertilizer use will help to counteract this trend while substantially improving food security.

Book excerpt: Food production remains the highest agricultural priority, subject to the constraint that it be done in harmony with nature, or at least with minimum environmental pollution. The amount of fertilizer applied can be controlled using modern application techniques, including soil and crop management, guaranteeing higher economic profit and lower environmental cost. It is in such a context that the present book addresses the efficient and rational use of mineral and organic fertilizers while preserving environmental quality. The book discusses the impact on surface and groundwaters, soils and crops, and experience of nitrate leaching, denitrification, ammonia volatilization, heavy metal pollution, agricultural and urban waste management, and international and national legislation. Audience: Agronomists, environmentalists, soil and food chemists, ecologists, policy makers, and managers in the fertilizer industry concerned with the trend of public opinion.

Book excerpt: This paper reviews the Bank's involvement in the fertilizer sector of developing countries to highlight the lessons that have been learned. Although the paper deals mostly with the supply and use of industrially based chemical fertilizers, it has benefitted from considerable internal debate by industrial and agricultural staff. It points out that Bank assistance at first consisted of helping finance and implement the construction of fertilizer plants, but lately the emphasis has shifted to ensuring better efficiency and reliability in getting this material to farmers at the lowest cost. It has major problems in many developing countries, such as excessive subsidies, suboptimal use of fertilizers, large administrative bureaucracies, and unprofitable factories. These problems are politically sensitive, but current World Bank work is helping to correct them, and this work needs to be publicized, and improved upon. The paper gives an overview of the global fertilizer industry, the needs for new investments, and the trends in trade, and technology. There is a review of the policy lessons being learned, and of past Bank activity. The paper closes with a review of some of the issues that need to be resolved, and recommends practical steps for international cooperation.

Book excerpt: The United Republic of Tanzania has a predominantly agricultural economy, with agriculture accounting for more than two-thirds of employment in rural areas and representing 30 percent of GDP. Yet, by global standards and even by the standards of Developing Countries, crop yields in the county are low. Using improved seeds and mineral fertilizers is therefore critical to promoting growth in crop productivity, food production and sustaining the natural resource base, especially among the smallholder farmers who subsist on nutrient-poor soils. In 2016, The Ministry of Agriculture, Livestock, and Fisheries (MALF) of the United Republic of Tanzania requested an assessment of the potential costs and benefits of a proposed Bulk Procurement System (BPS) for fertilizer imports that would consolidate international procurement to save costs, ultimately improving the affordability for farmers. This assessment was jointly carried out and submitted to MALF in 2017 by FAO and the International Fertilizer Development Centre (IFDC), and presents an analysis of the fertilizer market, the proposed BPS policy, and interviews with over one hundred public, private, and civil society stakeholders. The findings indicate that the proposed system would likely not reduce prices for farmers and could negatively affect availability and market competition – causing prices to increase in the long term. The authors therefore recommend against its implementation pending further consultations, or to pilot the system with careful review and evaluation. The report also presents alternative policy options for the short and medium term to improve overall efficiency in the value chain and ultimately make fertilizer more affordable for Tanzanian smallholder farmers.
