Fertilizer Use and Price Statistics, 1960-93

Author
Harold H. Taylor

Abstract: The rapid growth in fertilizer consumption throughout the sixties and seventies peaked at 23.7 million nutrient tons in 1981. After falling to 18.1 million tons in 1983, use has remained relatively stable, ranging from 19.1 to 21.8 million tons during 1984-93. Use has declined from its peak level because of fewer planted acres and stabilizing rates of application. Farm fertilizer prices, while stable or declining during the sixties, have varied widely since 1973. This bulletin includes quarterly or semiannual time series for farm fertilizer prices, annual, farm and wholesale fertilizer price indexes, fertilizer consumption by plant nutrient and major selected products, consumption of mixed fertilizers and secondary and micronutrients, and statistics on fertilizer use per acre by nutrient in the major producing States for corn, cotton, soybeans, and wheat.

Constraints to fertilizer use in Nigeria

Author

Abstract: Fertilizer consumption rates in Nigeria remains among the lowest in the world despite decades of aggressive subsidization. The extension service in Nigeria has a double-edged impact on fertilizer use in the country; not only can their activities increase farmers’ demand for fertilizer, but also the organizational framework of the service, Agricultural Development Programs, is the major source of fertilizer for farmers. To provide insights on the reasons for the low fertilizer use in Nigeria, this paper presents an analysis of the extension service as well as some perspectives of village extension agents. We find that the reach of the extension service is severely limited by low staff. The main technology transmitted is the use of improved seeds. Fertilizer technology is seldom transmitted and very rarely is irrigation taught. Furthermore, extension agents are found to have gaps in their knowledge of fertilizer technology. Extension agents routinely distribute agricultural inputs and many see their advisory role as secondary to this function. Extension agents identified the primary constraint to fertilizer use in Nigeria as the physical absence of the product at the time that it is needed, rather than lack of affordability or farmers’ lack of knowledge about the benefits or the use of fertilizer.

Readdressing the Fertilizer Problem

Author

Abstract: The production literature has shown that inputs such as fertilizer can be defined as risk-increasing. However, farmers also consistently overapply nitrogen. A model of optimal input use under uncertainty is used to address this paradox. Using experimental data, a stochastic production relationship between yield and soil nitrate is estimated. Numerical results show that input uncertainty may cause farmers to overapply nitrogen. Survey data suggest that farmers are risk averse, but prefer small chances of high yields compared to small chances of crop failures when expected yields are equivalent. Furthermore, yield risk and yield variability are not equivalent.

The supply of inorganic fertilizers to smallholder farmers in Tanzania: Evidence for fertilizer policy development

Author
Todd Benson (t.benson@cgiar.org), Stephen L. Kirama and Onesmo Selejio

Abstract: This paper presents the results of a broad study of fertilizer supply to smallholder farmers in Tanzania that was done to assess whether the taxes (explicit or implicit) that are applied at various points along the fertilizer importation and marketing chain or the absence of key public goods and services reduces the access that smallholder farmers have to fertilizer. The study involved a review of the literature of fertilizer supply, demand, and use; interviews with key participants in fertilizer importation and marketing in Tanzania; and two surveys—one with farmers and the other with input suppliers—in three farming areas where more fertilizer is used than is the norm for the country as a whole.

Understanding the role of research in the evolution of fertilizer policies in Malawi

Author
Michael E. Johnson and Regina Birner (regina.birner@uni-hohenheim.de)

Abstract: This study examines the role of research in agricultural policy making in Malawi at a time when the Africa Union and the New Partnership for Africa’s Development have been seeking to promote greater evidenced-based decision making in agriculture. Drawing on both theory and actual past experiences documented in the literature, results are intended to improve our understanding of the extent to which research has played any role in influencing policy change in Malawi. This is done in the context of the evolution of the country’s fertilizer subsidy policies.

Regional differences in the level of consumption of mineral fertilizers in Poland

Author

Additional contact information

Abstract: The article studied regional differences in the level of fertilization in Poland. Analyzed the potential factors influencing the differences in fertilization between voivodeships. In order to study regional differentiation in mineral fertilizers used cluster analysis (Ward's method). As a result of grouping objects received five clusters of of voivodeships. A group of of voivodeships differed in terms of the proposed features, while the voivodeships within the group were characterized by similar values of variables. The voivodship with the highest level of mineral fertilization characterized by the largest area of farms, the largest share of sowings in the agricultural area, the largest share of farms specializing in field crops and the largest level of calcium fertilization. It may be assumed that the farmers of these voivodeships have obtained the best results from agricultural activities, which favored investing in agricultural inputs.

Poverty program participation and employment in timber-dependent counties

Author

Authors registered in the RePEc Author Service: Sandra A. Hoffmann

Abstract: This paper uses cointegrated time-series methods to evaluate the effect of timber employment on participation in a major poverty program-Aid to Families with Dependent Children-Unemployed Parent (AFDC-UP). The study is conducted for major timber-producing counties in California. It is shown that a two-sector structural model can be solved to produce an error-correction model. An error-correction model is estimated with time series on state and county AFDC-UP caseload, state employment, county nontimber employment, and county timber employment. Utilizing tests on the cointegrating space, it is shown that there is no long-run relationship between poverty and timber employment in 10 of the 11 counties studied.

EAS Strategic Options, 2013, vol. 2013, issue 18, pages 14-15

Abstract: Europe has been in prolonged debt crisis and the markets including timber products were badly affected. Since the 1970?s, European market has been one of the traditional markets for Malaysian timber products, particularly sawntimber. Currently, Malaysia is facing many competitors (especially Brazil and China) in the export of timber products to the European market. To what extent is Malaysia affected by the increasing international competition and what are the steps necessary to remain competitive?
