What does a fertilizer analysis of 0-46-0 primarily indicate?

A fertilizer analysis of 0-46-0 reveals the composition of primary nutrients in that specific fertilizer blend, where the numbers represent the percentage of nitrogen, phosphorus, and potassium, respectively. The first number (0) indicates that there is no nitrogen present in this fertilizer, meaning it does not contribute to the nitrogen needs of plants.

The second number (46) signifies a high phosphorus content, which is critical for root development, flowering, and overall plant energy transfer. Phosphorus is vital during the early growth stages of plants and plays a role in photosynthesis, energy transfer, and the synthesis of nucleic acids.

The third number (0) shows that there is also no potassium in this fertilizer. Therefore, the analysis primarily indicates a fertilizer high in phosphorus but deficient in both nitrogen and potassium. This makes it particularly useful in situations where a boost in phosphorus is needed, such as during planting or in soils that are low in this critical nutrient.
