A fertilizer with an analysis of 0-46-0 is known as what?

The fertilizer with an analysis of 0-46-0 contains no nitrogen and no potassium but is high in phosphorus, which is indicated by the second number in the analysis. This specific formulation is known as Triple Superphosphate. Triple superphosphate is produced by treating phosphate rock with sulfuric acid, resulting in a concentrated source of phosphorus that is readily available for plant uptake.

This nutrient is critical for various plant functions, including root development, flower and fruit production, and overall growth. The high phosphorus content makes it particularly beneficial for crops during the early stages of growth or in flowering stages where robust root and fruit development is crucial.

The other options provided do not match the analysis of 0-46-0. For instance, Monoammonium phosphate (MAP) has a different nutrient composition that includes nitrogen, while potassium nitrate and urea focus on providing either potassium or nitrogen, respectively, making Triple Superphosphate the only correct identification of the nutrient profile described.
