Phosphorus (P)

Last updated: December 27, 2018

What Does Phosphorus (P) Mean?

Phosphorus is a macronutrient that is crucial for healthy plant growth and development. This nutrient is particularly important because it encourages blooming, root development, seed production, and leaf development. A lack of phosphorus can result in stunted growth or even death in plants. Over-application of phosphorus is just as dangerous to plants because it can affect the water quality if runoff occurs.


Maximum Yield Explains Phosphorus (P)

The majority of commercial fertilizers contain a mixture of potassium, phosphorus, and nitrogen. Fertilizers that only contain phosphorus are known as super-phosphates and are normally derived from certain nutrients and minerals that are acid-treated.

The appropriate application technique depends on the type of phosphorus fertilizer that is applied to the plants. For example, granular fertilizer can be raked into plant beds or sprinkled over flowers. In some cases it is also possible to mix the phosphorus-enhanced granular fertilizer directly into the topsoil. Liquid phosphorus fertilizer, on the other hand, can be poured or sprayed in the plant beds. It is recommended to avoid spraying the phosphorus solution directly on the leaves because this can burn and destroy the plant.
