Abstract

Historically nutritional studies of anoxic plants have simply
catalogued concentration and uptake changes of treated plants,
frequently on a non-partitioned whole-plant basis. Major reviews of
soil aeration and flooding generally agree that N, P, and K
concentrations in plants are reduced by anoxia (Kozlowski, 1984;
Glinski and Stepniewski, 1985). Sodium concentration increases and
other major elements either remain unaffected or react irregularly.
Until recent years explanations of nutritional changes have focused
chiefly on alterations in the poorly aerated soil physicochemical
environment. Factors such as: increased mineral solubilization,
leaching, and dilution in high water content soils, increased water
film coverage of roots, altered ion diffusion, solubility changes at
altered valence states, altered pH resulting from redox reactions
or increased CO2 concentrations, etc. have been used to explain
nutritional responses to oxygen-limiting soil environments.
