Eco-friendly Synthesis of Calcium Nitrate Fertilizer from Industrial Limestone Waste
Annotatsiya
This research investigates the potential application of limestone waste, sourced from the Andijan deposit, as a viable raw material for the synthesis of granular calcium nitrate fertilizers. The study employs a systematic process wherein calcium-rich limestone residues are treated with nitric acid to facilitate the conversion into a nitrogen-enriched compound. Subsequent granulation of the resultant material yields a high-quality granular fertilizer with enhanced agronomic value. This approach underscores a sustainable and innovative strategy for valorizing industrial mineral by-products, thereby contributing to waste minimization and promoting environmentally responsible agricultural inputs. The findings demonstrate the feasibility of transforming locally available mineral waste into a product with considerable significance for improving soil fertility and crop productivity, aligning with circular economy principles and sustainable agricultural development.
