State about the Oxidised forms of elements

Oxidised forms of elements are more desirable for most common crops grown in acid soils and humid regions while the reduced forms of Mn and Fe are toxic to plants in acid soil.  In drier soils, opposite is true when Fe²⁺ and Mn²⁺ are preferred.  In neutral and alkaline dry soil Fe³⁺, Mn⁴⁺ and other micronutrient metal ions get precipitated resulting in their deficiency.
