Abstract:
Zn2+ and phosphate groups are crucial plant nutrients for several plant species. However, uptake and
availability of these ions in most plants face negative synergy from themselves and other factors. While
use of organic fertilizers has numerous advantages over inorganic ones, it has been criticized to support
antagonism of Zn2+ uptake in plants. This mini review sought to address some of the factors leading
to antagonism of Zn2+ uptake in plants in the presence of inorganic phosphate groups (Pi) and other
organic moieties. Herein, we address these factors from a molecular and psychological perspective. We
also describe some of the structural and bonding factors leading to formation of insoluble and immobile
Zn2+ complexes in plants in organic moieties. The authors conclude that organic fertilizers meant for
application needing high Zn2+ such as in seedbeds and during drought seasons should include chelating
agents or rice straws that ameliorate soil pH.
