Dark and Light Peat Casing Soils Suppress Populations of Listeria b Salmonella

摘要

We know from the horticultural literature that high populations of harmless microorganisms in peat-based plant soils have significant effects on the quality and yield of vegetable crops. When light peat that is rich in microorganisms is replaced withdark peat that contains comparatively lower microbial levels, the developing plants tend to become more susceptible to diseases. Peat products are widely used in the mushroom industry to prepare casing soils and in recent years, partial replacement of light peat with dark types has become more common.
