Tin is an immobile element in arable soil, especially at neutral pH, which causes a low intake by plants. A decrease in soil pH results in a higher content of soluble forms of Sn and in consequence a higher Sn absorption by plants. Usually the concentration in plants ranges from <0.10 to 3.0 mg kg −1. Plants are able to …
