Effects of fertilizers on the root of Avena strigosa and behavior of Folsomia candida

The aim of this work was to evaluate the effects of increasing doses of mineral and organic fertilizers on the root chemotaxis of Avena strigosa and avoidance of Folsomia candida. Five soil samples were used for the mineral fertilization with NPK and other five soil samples were used for the organic fertilization with poultry litter-based organic fertilizer. The experiment included control soils (without applications) and soils containing 4-, 8-, 16- and 32-ton fertilizer per ha. A. strigosa was planted and cultivated in the soils for 14, 21, 28 and 35 days and avoidance behavior of F. candida. The root amounts in the soils containing mineral fertilizer were higher than those of the soils containing poultry litter-based organic fertilizer. The avoidance behavior of F. candida from the soils containing poultry litter-based organic fertilizer increased from 8- to 32-ton ha-1. Applications of high poultry litter-based organic fertilizer doses in soil increase the toxic effects for A. strigosa and F. candida.
