Description

Controlled environment and field studies have shown that the establishment and subsequent growth of Trifolium repens L. and Lolium perenne L. is adversely affected by high soil moisture contents. The purpose of the research described in this paper was to determine whether or not coating the seed of the two species with an oxygenating compound improved plant emergence and shoot growth. Coated and uncoated seed of both species experienced high soil moisture contents in field plots at an upland site and were also subjected to temporary water logging in pots under glasshouse conditions. The adverse effects of waterlogging in the field and in a controlled environment were partially mitigated by coating the seed with calcium peroxide. Alleviation of the detrimental effects of excessive soil moisture contents was observed in plants which were established from seed coated with calcium carbonate. This programme of research has demonstrated that the adverse influence of saturated soils on the emergence and seedling growth of two important forage plants was ameliorated by peroxides which slowly decompose in the soil.
