Storage method affects disease suppression of flax wilt induced by composts

Compost can have a disease suppressive effect, but compost research is constrained by the fact that repetition of experiments with a similar batch of compost is impossible, since storage affects the organic material including the microbial communities. The objective of this study was to test the hyp...

Description
Summary:Compost can have a disease suppressive effect, but compost research is constrained by the fact that repetition of experiments with a similar batch of compost is impossible, since storage affects the organic material including the microbial communities. The objective of this study was to test the hypothesis that differential changes in microbial community structure and associated microbial activities after various storage methods (drying, freezing and cooling) lead to differential changes in the disease suppressive ability of compost material with respect to Fusarium oxysporum f. sp. lini induced by mixes of composts with peat substrate (20/80%, vol./vol.).
