Abstract
This material discusses the production and marketing of suspension fertilizers from solid materials, focusing on the advantages of fluid fertilizers over solid ones. The authors highlight the ease of mixing and uniform application of pesticides as a significant advantage of fluid fertilizers, along with other properties such as accuracy of application, low salt index, and the ability to mix and apply secondary and micronutrients uniformly. Traditionally, fluid fertilizers have been considered premium products due to their advantages and higher prices resulting from the costlier phosphate materials used in their production. However, in the face of rising costs and the need for cheaper raw materials, using solids to produce fluids has gained traction. The authors explore the use of monoammonium phosphate (MAP) and diammonium phosphate (DAP) as popular solid bases for fluid fertilizers, discussing their solubility and production methods. The potential use of triple superphosphate and ammonium polyphosphate (APP) as phosphate sources in fluid fertilizers is also mentioned. Overall, the material provides insights into the historical development and current practices of producing suspension fertilizers from solid materials.
