Superphosphate is a type of fertilizer made by treating rock phosphate with sulfuric acid. This process converts the phosphate rock into a more soluble form, making it easier for plants to absorb. Superphosphate is rich in phosphorus, an essential nutrient that promotes root development and flowering in plants. Farmers often use superphosphate to enhance soil fertility and improve crop yields. It is particularly beneficial for crops like corn, wheat, and potatoes, which require high levels of phosphorus. By adding superphosphate to the soil, growers can ensure their plants receive the nutrients they need for healthy growth.
