Superphosphate of lime is a widely used fertilizer in agriculture. The correct spelling of this word is /ˌsuːpərˌfɒsfeɪt əv laɪm/. The first syllable "su" is pronounced like "soo" and the "per" is pronounced like "pur". The "phos" in the middle is pronounced like "foss" and the "pha" at the beginning is pronounced like "fay". The word "of" is pronounced as "ov", and "lime" is pronounced like "laɪm-". This pronunciation guide helps ensure that both the spelling and the pronunciation of the word are accurate.
Superphosphate of lime is a type of fertilizer that consists of calcium dihydrogen phosphate, derived from phosphate rock and treated with sulfuric acid. It is widely used in agriculture to supply phosphorus, an essential nutrient required for plant growth and development. The term "superphosphate" refers to the high solubility of the compound in water, making it readily available for plants to absorb.
Superphosphate of lime is commonly produced through a chemical reaction, wherein finely ground phosphate rock is mixed with sulfuric acid. This reaction results in the formation of calcium phosphate and gypsum. The calcium phosphate present in the mixture is highly soluble in water, facilitating its uptake by plants through their root systems. This attribute of superphosphate of lime makes it a popular choice among farmers looking to enhance the phosphorus content in the soil.
The application of superphosphate of lime offers numerous advantages in agriculture. It improves both the quantity and quality of crop yields by promoting root development, flowering, and fruit formation. Phosphorus is crucial for energy transfer within plants, aiding in metabolic processes, and enhancing overall plant growth. Additionally, superphosphate of lime helps in the development of stronger stems and roots, leading to enhanced resistance against diseases and environmental stress.
It is important to note that the excessive use of superphosphate of lime can have detrimental effects on the environment, such as the contamination of water bodies with excess phosphorus. Therefore, its application should be carried out judiciously, considering the specific needs of the crops and the existing phosphorus levels in the soil.
In agri., a fertiliser prepared from ground bones, bone-black, or phosphorite, treated with sulphuric acid.
