What is Superph 21 Fertilizer?

Superph 21 refers to a type of superphosphate, a phosphorus-rich fertilizer produced from rock phosphate. It contains approximately 21% phosphorus pentoxide (P2O5), making it an excellent source of this essential nutrient for plants. Phosphorus is critical for a range of plant functions, including energy transfer, photosynthesis, and the synthesis of nucleic acids and ATP (adenosine triphosphate).

The production of Superph 21 involves a chemical reaction between phosphoric acid and a source of calcium, typically through treating rock phosphate with sulfuric acid. This process results in a more accessible form of phosphorus for plants compared to untreated rock phosphate, which is often less available due to its insolubility.

Superphosphate can be broadly categorized into two types: single superphosphate (SSP) and triple superphosphate (TSP). Superph 21 falls under the single superphosphate category, characterized not only by its phosphorus content but also by the presence of essential secondary nutrients, such as calcium and sulfur. This fertilizer is typically granulated, allowing for easy application.
