Abstract: Calcareous soils that are found in arid and semi-arid areas pose great challenges to agriculture because of their high PH and calcium carbonate content that reduce the availability of nutrient especially phosphorus, iron and zinc. The fertilizers manufactured to address these issues include acidity production fertilizers, which are elemental sulfur, ammonium-based compounds, and organic amendments, which help in reducing the pH of soils and increase the solubility of nutrients. These fertilizers can be oxidized through the microbial oxidation and nitrification process to release hydrogen ions, which enhance the nutrient absorption and the production of crops. As an example, the application of elemental sulfur can provide phosphorus up to 30% more (Zhang et al., 2023) ^[27], and ammonium sulfate can help to improve the amount of nitrogen (Trenkel, 2010) ^[25]. Organic amendments such as compost also enhance the health of the soil by encouraging the growth of microorganisms and structure (Bernal et al., 2017) ^[1]. Such fertilizers control the leaching of nutrients, increase agricultural sustainability and reduce environmental effects, which is in line with the global food security objectives (FAO, 2020) ^[7]. Nevertheless, issues like price and accuracy of implementation need more research on cost effective formulas and accuracy technologies. The abstract gives attention to the processes, uses, and sustainability advantages of the acidity production fertilizers, and the need to make use of them in the management of calcareous soils to achieve better agricultural production.
