Description

Superphosphates are a vital group of phosphate fertilizers produced by the acidulation of phosphate rock, primarily valued for their high water-soluble phosphorus content essential for plant growth. This product, Superphosphates CAS NO 8011-76-5, is a cornerstone for enhancing soil fertility and boosting crop yields in modern agriculture. It is a critical input for fertilizer manufacturers, agricultural cooperatives, and large-scale farming operations globally seeking to improve phosphorus availability in a wide range of soil conditions.

Application

• Primary Agricultural Fertilizer: Direct application or as a key ingredient in NPK compound fertilizers to provide readily available phosphorus (P2O5) for root development and crop maturity.
• Soil Amendment: Used to correct phosphorus-deficient soils, improving soil structure and enhancing the efficiency of other nutrients like nitrogen.
• Horticulture and Turf Management: Formulated into specialty fertilizers for lawns, gardens, golf courses, and nurseries to promote strong root systems and plant vigor.
• Animal Feed Supplement: Serves as a source of digestible phosphorus in mineral premixes for livestock and poultry nutrition.
• Industrial Processes: Utilized in certain chemical manufacturing processes and as a fluxing agent in metallurgy.

Quality Control

Our Superphosphates are manufactured under strict process controls to ensure consistent quality and performance. Each batch is analyzed for key parameters including available phosphorus pentoxide (P2O5) content, free acidity, and moisture to meet industry and customer specifications. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the product must be kept in original packaging or sealed containers to prevent caking and degradation from atmospheric moisture. Recommended storage temperature is 15-25°C.
