DOWNLOAD EBOOKThis bulletin is a collection of abstracts on Fertilizer Marketing selected from those appearing in Fertilizer Abstracts between July 1973 and June 1978. A similar collection was made of the material from January 1968 through June 1973, and is available in Bulletin Y-59. Together the two bulletins contain nearly 2000 abstracts and cover the majority of marketing publications over the past 10.5 years.

DOWNLOAD EBOOKAgriculture continues to play an important role in African economies. 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.

DOWNLOAD EBOOKThis Fertilizer Manual was prepared by the International Fertilizer Development Center (IFDC) as a joint project with the United Nations Industrial Development Organi zation (UNIDO). It is designed to replace the UN Fertilizer Manual published in 1967 and intended to be a reference source on fertilizer production technology and economics and fertilizer industry planning for developing countries. The aim of the new manual is to describe in clear, simple language all major fertilizer processes, their requirements, advan tages and disadvantages and to show illustrative examples of economic evaluations. The manual is organized in five parts. Part I deals with the history of fertilizers, world outlook, the role of fertilizers in agriculture, and raw materials and includes a glossary of fertilizer-related terms. Part II covers the production and transportation of ammonia and all important nitrogen fertilizers-liquids and solids. Part III deals with the characteristics of phosphate rock, production of sulfuric and phosphoric acid, and all important phosphate fertilizers, including nitrophosphates and ammonium phosphates. Part IV deals with potash fertilizers-ore mining and refining and chemical manufac ture; compound fertilizers; secondary and micronutrients; controlled-release fertilizers; and physical properties of fertilizers. Part V includes chapters on planning a fertilizer industry, pollution control, the economics of production of major fertilizer products anJ intermediates, and problems facing the world fertilizer industry.
