Zn deficiency in wetland soils

Zn deficiency in wetland soils-Explain

The major factors associated with the occurrence of Zn deficiency are considered to be the weathered parent material, nature of clay minerals, alkaline pH, high salt concentrations, calcareousness, waterlogging or flooding, organic matter content, high magnesium or bicarbonate concentrations (also in irrigation water), more nutrient uptake than application, intensive cultivation and the use of high analysis fertilizers (i.e., poor in micronutrients).  

The fields along of soils with the wet conditions and increasingly poor drainage downslope confirmed that zinc deficiency is most severe in these soils. That means Zn deficiency arises in most poorly drained areas and wetland soil. This is happening due to lack of soil aeration during the dry season and high organic matter contents in the wettest fields which are subjected to the upwelling of water, seem to be mainly responsible for the very low availability of zinc.

High pH and high levels of dissolved magnesium bicarbonate may contribute to the disorder. When soil in water logged condition soil aeration greatly hampered in concentration of dissolve magnesium bicarbonate increases that’s why Zn deficiency arises in wetland soil.
