Abstract
Waterlogging of sodic soils varying widely in pH values, ECe, and Exchangeable Sodium Percentages (ESP) increased the availability of Fe by 3.9‐fold and Mn by 3.3‐fold compared with availability of Fe at field capacity soil moisture content over a 14‐day period. Gypsum treatment of sodic soils under waterlogged conditions further improved the available Fe and Mn status above their critical limits. When additional Fe or Mn was applied, there was no response in yield or uptake of Fe or Mn by rice (Oryza sativa L.) or wheat (Triticum aestivum L).
