Once inside plants, nutrients are transported to where they are needed, typically to growing points. Once incorporated by the plant, some elements can be immobile while others can be remobilized. Immobile elements essentially get locked in place and that is where they stay. Those that can be remobilized can leave their original location and move to areas of greater demand. Knowing which are mobile or immobile is helpful in diagnosing deficiency symptoms.

Since immobile elements do not easily move within the plant, when deficiency symptoms occur they show up in new growth When mobile elements become limiting, they can be scavenged from older growth and moved to where they are most needed, causing deficiency symptoms in older growth

Nutriet deficiency Nutriet deficiency
Typical deficiency symptoms of a non- mobile nutrient (iron) within the plant. Note newer leaves are more affected. Typical deficiency symptoms of a mobile nutrient (nitrogen) within the plant. Note older leaves are senescing while younger leaves are still green.

Most nutrient deficiencies need a certain amount of time after growth begins for symptoms to occur. Early growth is often not fast enough or of a great enough volume for symptom expression. Deficiencies are often revealed when the plant is at maximum growth or at other times of high nutrient demand such as fruit development.

According to Michigan State University Extension, nutrient deficiencies can be due to a number of reasons. The most obvious is that the element is not in a high enough level naturally in the soil. Many sand-based soils with high leaching potential are often low in highly soluble nutrients. In some cases, the element is in adequate levels, but unavailable due to pH being too high or too low or the soil temperature being too low for adequate uptake. Other reasons could be too little or too much water or soil compaction. Remember all mineral elements need to come from the soil and if water uptake is interrupted for any reason, so is nutrient uptake.

Thank you, tucking these into my tickle trunk for growing

I really like the element breakdown, what is the yes/no column? (Required by or provided by or something else?)

 

[NAKEDGARDENER]

Yes no column is denoting whether it is mobile or immobile in the plant.. thanks for pointing that out.

 

[9fingerleafs]

it must be mobility lurking
