Abstract

The application of biocides may create unintended consequences on soil biota and ecosystem stability. The inputs of organic matter can increase biocides adsorption and reduction of non-target organisms influence. A field experiment was conducted to study the changes of soil abiotic and nematode communities resulting from biocides application in non-litter-added and litter-added soils in Illicium verum forest. Our results showed that litter addition could change the responses of soil nematodes to biocides. The influence of fungicide was evident mainly in litter-added plots in which it increased nematode abundance. Insecticide and its interaction with fungicide significantly decreased the diversity index and the abundance of omnivores-predators and herbivores in non-litter-added plots. While, insecticide had little effect on nematode diversity and abundance in litter-added plots. Litter addition may help to maintain the structure and stability of soil food web and result in bacteria dominant decomposition pathway. Our results suggest that litter addition may be a critical factor for maintaining soil ecosystem stability when biocides are applied in Illicium verum forest.
