Measurement of isotopically-exchangeable Zn in Zn-deficient paddy soil [PDF]

, 2015
The changes in soil chemistry following submergence of a soil for rice production result in zinc (Zn) being immobilized in very insoluble forms. Consequently, Zn deficiency is widespread in rice crops and in human populations that subsist on rice.
