Influence de l'épandage de différents types de lisiers sur la contamination des fourrages et du sol par des spores de Clostridium. Partie I. Influence de l'origine du lisier, de sa fluidité et de l'epaisseur du tapis vegetal sur la contamination de l'herbe et du sol

Abstract - Effect of spreading different types of manure on contamination of forages and of the soil by Clostridium spores. Part I. Effect of the origin of the manure of its fluidity and of the thickness of the plant
Results show that spreading manure increased spores concentration in the grass and that decontamination was slow. The fluidity of the manure had little importance for the volumes spread during the experiment.
Thus, we conclude that contamination would be low at the end of the month if the manure does not contain more than 10⁴ spores per mL, and if the grass is not thick. Consequently, the quality of silage given to animals is of considerable importance
