Deficiency symptoms of essential elements
-
When the plants are grown in magnesium deficient but urea rich soil, the symptoms expressed are :Magnesium is the central atom of the chlorophyll molecule.
Even if nitrogen (from urea) is plentiful, chlorophyll cannot be made without magnesium. So the leaves lose their green colour and turn yellow (chlorosis), first in the older leaves, because Mg is mobile and moves to the young leaves.
So the plants show yellowish leaves.
That is every question in Mineral Nutrition for this filter.
