    Cotton Fertilizer in West Africa
    (2022-11-10) Patrice Annequin
    This study examines the rapid expansion of the fertilizer market in West Africa, focusing on key metrics related to consumption, production, and utilization for cotton cultivation in eight countries. The fertilizer market has experienced substantial growth, with consumption doubling since 2010. However, a crisis in 2022 has resulted in a significant shortage of fertilizer in the region. The paper explores the dynamics of cotton production in Benin, Burkina Faso, Mali, and other West African countries, highlighting the challenges and variations in social contexts. The analysis includes forecasts for cotton acreage and production, with emphasis on fertilizer consumption patterns. The study also delves into the distribution of fertilizer use across countries, revealing that the top four nations account for 85% of total consumption. Additionally, the research explores the fertilizer consumption per country for cotton production, detailing the specific NPK (Nitrogen, Phosphorus, Potassium) grades used. The paper concludes with an investigation into the strategies employed for fertilizer procurement and distribution in West African countries, particularly during crisis times. The study suggests improvements in procurement processes, trade finance, subsidy programs, and nutrient use efficiency to enhance the overall fertilizer market in the region.

    The Agronomic Properties of a Newly Developed Fused Ammonium Sulfate Nitrate (Sulf-N26) for Crop Production: Preliminary Results
    (2011) Sen H. Chien; Upendra Singh; Gearhart, M. Mercedes
    This study investigates the agronomic properties of a newly developed fused Ammonium Sulfate Nitrate (ASN) fertilizer, trademarked as "Sulf-N26," in comparison to traditional granulated ASN. The fused ASN is created through a patented fusion process by Honeywell, which eliminates issues related to explosive potential and caking associated with traditional ASN mixtures. The study aims to determine if the chemical process of fusion affects the agronomic characteristics of Sulf-N26 compared to granulated ASN, including NH3 volatilization, leaching of nitrogen (N) and sulfur (S), and its effectiveness in promoting crop growth. Various N and S sources are also included in the analysis. Preliminary results indicate reduced NH3 volatilization and leaching of NH4-N and SO4-S in soils with fused ASN, making it a promising alternative for crop production. The fused ASN demonstrates comparable efficacy to granulated ASN and urea as a nitrogen source for wheat grain yield and as a sulfur source for ryegrass and canola crops.
