Superphosphate of lime is a commonly used fertilizer in agricultural practices. It is also known as Triple Superphosphate, TSP, or phosphatic fertilizer. This fertilizer is obtained by treating ground phosphate rock with sulfuric acid. The resulting phosphorus-rich material is then processed into fertilizers. Superphosphate of lime is an important source of phosphorus, a crucial nutrient for plant growth. Apart from phosphate rock, other sources of this nutrient include bone meal, rock phosphate, and guano. Synonyms for superphosphate of lime include concentrated superphosphate, double superphosphate, and treble superphosphate. All these fertilizers contain varying amounts of phosphorus, which can be adjusted based on the crop's requirements.
