Mobile and Immobile Nutrients - Table of content

What are mobile nutrients

Mobile nutrients, like Nitrogen, are able to move from one portion of the plant to another as needed.
You can notice this for example when you have a Nitrogen deficiency. The lower plant will take the nutrients from lower leaves in order to reuse the nitrogen in the upper levels of the plant.
You can see this with the leaf turning yellow, which indicates that the nitrogen is being sucked out of it.

How to know if the nutrient is mobile?

If the deficiency impacts the older leaves first then odds are that the nutrients is mobile since this shows that the plant is extracting the nutrient in order to re-allocate it where it’s needed.

What are immobile nutrients

Immobile nutrients, like Calcium, are the opposite of mobile nutrients (duh); meaning that the plant cannot relocate the nutrients as needed.
If the plant goes through a deficiency the nutrients will not be reallocated.

How to know if the nutrient is immobile

If a plant goes through a deficiency of an immobile nutrients the new growth will be affected, since the plant cannot reallocate these nutrients where it’s needed.
