Tin for the plant: yellow leaves in summer
Tin (= Stannum) (Sn)
For the plant – yellow leaves in summer
In plants tin was discovered in 1855. The tin content in plants varies widely, with the highest amounts found in sunflower seeds and peas.
Plants do not absorb tin equally. For example, cranberries and blueberries collected in a forest located even 25 km from busy highways contain about 40 mg of tin per 1 kg of berries (the norm is 2 mg/kg).
Leaves that turn yellow out of season indicate the accumulation of tin in them and the displacement of magnesium, as the loss of magnesium in plants causes chlorosis.
In vegetables, the concentration of tin is low and usually equals 1 µg/g or less.
Indicator plant that grows in soil with high tin content is the European starflower Trientalis europaea L., Primulaceae.
