Crop residue displacement by soil inversion: Annelid responses and their impact on carbon and nitrogen dynamics in a lab-based mesocosm study

In the context of sustainable agriculture, a deeper knowledge effects soil management on annelids is needed, as they play an important role in many processes. laboratory mesocosm experiment, we compared simulated effect ploughing by inverting top (crop residues at 15 cm depth) to non-inversion treatment surface) using type Haplic Luvisol. We investigated response earthworms and enchytraeids consequences for microbial chemical parameters. Four treatments with fauna were established adding: (i) endogeic (Octolasion cyaneum), (ii) anecic (Lumbricus terrestris), (iii) combination two enchytraeid species (Enchytraeus crypticus Enchytraeus christenseni) (iv) having control columns (without annelids). Feeding behaviour was isotopic analysis (?13C, ?15N), properties measured. Carbon nitrogen losses form gas emissions (CO2, N2O) leachate recorded during time incubation. found no interactions inversion annelid addition properties; these closely related crop residue placement, indicated between 0 20 cm. Below cm, this disappeared. Here, presence enhanced properties, regardless inversion. Stimulating activity increasing aeration seem be most factors that increase CO2-C earthworms. N2O-N consistently higher (+188%) inverted columns. Our results show placement residues, fed more derived carbon than earthworms, while appeared avoid feeding surface. Moreover, it did not interact experimental setting where carried out without detracting or impairing directly.
