Download or read book Fertilizer Quality Assessment Perception versus testing in selected Ghanaian districts written by Asante, Seth and published by Intl Food Policy Res Inst. This book was released on 2021-12-23 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertilizer use in Sub-Saharan Africa remains below recommended rates, contributing to low yields, and increasing poverty. Poor quality fertilizer – whether perceived or real – is often cited as a reason for low adoption rates. In Ghana, for example, there are widespread but often unsubstantiated claims of substandard fertilizers. This is a concern for farmers with limited purchasing power and without the means to independently substantiate the quality of agricultural inputs. This paper describes the agricultural input sector in Ghana, compares farmers’ perception of fertilizer quality with those of input dealers, and analyses chemical tests of fertilizers performed in a laboratory. The fertilizers were sampled from selected districts participating in the Planting for Food and Jobs initiative, a large-scale farm input subsidy program. We find that input dealers and farmers are somewhat suspicious of the quality of commercially supplied and government subsidized fertilizers. However, the true quality measures based on laboratory testing of fertilizers sold in agricultural input shops were found to largely meet the labeled chemical composition.

This book was released on 1998-03-31 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fertilizer Manual, 3rd Edition, is a new, fully updated, comprehensive reference on the technology of fertilizer production. The manual contains engineering flow diagrams and process requirements for all major fertilizer processes including ammonia, urea, phosphates, potassium products and many others. Environmental considerations are addressed clearly. Equally important, the manual includes chapters on fertilizer use, production and distribution economics, raw materials, and the status of the fertilizer industry with demand-supply projections. Professionals involved with any phase of fertilizer production, use, marketing, or distribution will find this book valuable.

This book was released on 2012-12-06 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much has been learned about the proper and judicious use of fertilizers. Fertilizer application by farmers has grown from an art to a science. As food producers have strived to increase crop yields by overcoming nutrient deficiencies the use of fertil izers has increased dramatically. This has created a large chemical industry capable of supplying the needed plant food elements. A more complete understanding of soil chemistry and plant nutrition has led to greater fertilizer use with improved fertilization methods and crop cultural practices. Improved fertilizer technology has led to the production of more efficient forms of fertilizer. The modem fertilizer industry and with it fertilization practices began in the humid countries of the world. The use of fertilizers in arid and semiarid regions was later in development, although agriculture had its beginning in semiarid and arid regions. The development offertilizer use is parallel to industrial development in various areas of the world.

This book was released on 2014-07-31 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper was written to help bolster the case and present visual evidence demonstrating why it is important to seriously consider spatial soil fertility variability in Ghana and to promote area-specific fertilizer recommendations. Using geostatistical analysis of soil samples collected from farmer plots in three districts (Tamale Municipality, Savelugu-Nanton, and West Mamprusi in northern Ghana), the paper analyzes spatial variations in soil fertility. The results clearly show that there are variations in soil pH, organic matter content, and available phosphorous even at the community level, supporting the need for Ghana to seriously consider location-specific fertilizer recommendations.
