Studies in soil and plant manganese | SpringerLink

Relationships between manganese content of oats grown at eight experimental centres and the water-soluble manganese and total manganese of the soil have been investigated. Uptake of manganese by the plant correlates highly significantly with water-soluble manganese of soil at each of eight centres. Regression equations of the formy=a+bx have been calculated for each centre, wherey=manganese ...

The Biochemistry of Manganese in Plants | SpringerLink

In plants Mn has a role in many biochemical processes. However, unlike other essential trace elements such as Cu, Zn, Fe and Mo which are usually integral components of enzymes, Mn usually acts as an activator of enzymes and is often able to be replaced by other metal ions. Manganese resembles Mg in its biochemical function and is involved in ...
