Summary

Redox and chemical analysis techniques have measured the decomposition of calcium peroxide-coated rice seed (Oryza sativa L.) under flooded padi conditions. Decomposition rates, even in acid soils at high temperatures, are show enough to extend over the oxygen demand period of the germinating seed.

Rice seeds coated with calcium peroxide are relatively stable and viable over a wide range of storage conditions.

Magnesium peroxide coatings decomposition at approximately half the rate of calcium peroxide coatings. Differences in alkalinity, cation and oxygen release rate make magnesium peroxide a useful alternative system to calcium peroxide.
