The present study aimed to elucidate and quantify the carbon (C) flow from both root and shoot litter residues into soil organic, extractable, microbial and fungal C pools. Using the shift in C stable isotope values associated with replacing C3 by C4 plants we followed root- vs. shoot litter-derived C resources into different soil C pools. We established the following treatments: Corn Maize (CM), Fodder Maize (FM), Wheat + maize Litter (WL) and Wheat (W) as reference. The Corn Maize treatment provided root- as well as shoot litter-derived C (without corn cobs) whereas Fodder Maize (FM) provided only root-derived C (aboveground shoot material was removed). Maize shoot litter was applied on the Wheat + maize Litter (WL) plots to trace the incorporation of C4 litter C into soil microorganisms. Soil samples were taken three times per year (summer, autumn, winter) over two growing seasons. Maize-derived C signal was detectable after three to six months in the following pools: soil organic C (C-org), extractable organic C (EOC), microbial biomass (C-mic) and fungal biomass (ergosterol). In spite of the lower amounts of root- than of shoot litter-derived C inputs, similar amounts were incorporated into each of the C pools in the FM and WL treatments, indicating greater importance of the root- than shoot litter-derived resources for the soil microorganisms as a basis for the belowground food web. In the CM plots twice as much maize-derived C was incorporated into the pools. After two years, maize-derived C in the CM treatment contributed 14.1, 24.7, 46.6 and 76.2% to C-org, EOC, C-mic and ergosterol pools, respectively. Fungi incorporated maize-derived C to a greater extent than did total soil microbial biomass. (c) 2011 Elsevier GmbH.

It is known that earthworms preferentially ingest sand grains mixed with organic material and it has been suggested that the mixture of sand and organic material during the gut passage may play an important rote in titter degradation and nutrient release, which may accelerate assimilation of nutrients by earthworms and likely enhance plant growth. In a greenhouse experiment, we investigated the effect of the anecic earthworm species Lumbricus terrestris and the endogeic earthworm species Octolasion tyrtaeum separately and in combination on carbon and nitrogen mobilisation from surface applied rye titter labelled with (13)C and (15)N. By mixing arable soil with 25% sand, we investigated the effect of the availability of sand. To quantify the mobilisation of (15)N, three rye seedlings were planted in each microcosm and analysed for isotope signature after 3 months of incubation. Mobilisation of (13)C was quantified by analysing the incorporation of label into the soil and earthworm tissue. Irrespective of the addition of sand the biomass of L. terrestris decreased during the experiment, whereas that of O. tyrtaeum increased in single species treatment and slightly decreased in the combined treatment with L. terrestris. The concentration of (13)C decreased white that of (15)N increased in the tissue of both earthworm species, with the effect being more pronounced in L. terrestris for (13)C and in O. tyrtaeum for (15)N. Both earthworm species increased shoot biomass, with the effect of L. terrestris (+80%) exceeding that of O. tyrtaeum (+28%) and maximum plant biomass in the combined treatment (+92%). Earthworms did not affect the (15)N concentration of rye plants, but sand significantly increased (15)N concentration of plants, presumably due to improving soil structure. Overall, the incorporation of (13)C into the soil was low and was significantly increased in presence of sand, with the highest enrichment in treatments without earthworms. The results indicate that the availability of sand does not increase effects of earthworms on litter degradation, nutrient release and plant growth. Rather, independent of soil sand content earthworms increase plant growth, whereas the presence of sand itself enhances the uptake of nitrogen from plant litter and the incorporation of litter carbon into the soil.

Arable soil with and without O. tyrtaeum was incubated with C-13/N-15-labelled rye leaves placed on plastic rings with gaze (64 mu m mesh size) to avoid incorporation of leaves by earthworms. The plastic rings were positioned either on or 3 cm above the soil surface, to distinguish between biotic and chemical/physical translocation of nutrients by fungi and leaching. Contact of leaves to the soil increased C-13 translocation, whereas presence of O. tyrtaeum reduced the incorporation of C-13 into the mineral soil in all treatments. Although biomass of O. tyrtaeum decreased during the experiment, more C-13 and N-15 was incorporated into earthworm tissue in treatments with contact of leaves to the soil. Contact of leaves to the soil and the presence of O. tyrtaeum increased cumulative (CO2)-C-13-C production by 18.2% and 14.1%, respectively. The concentration of the fungal bio-indicator ergosterol in the soil tended to be increased and that of the fungal-specific phospholipid fatty acid 18:2 omega 6 was significantly increased in treatments with contact of leaves to the soil. Earthworms reduced the concentration of ergosterol and 18:2 omega 6 in the soil by 14.0% and 43.2%, respectively. Total bacterial PLFAs in soil were also reduced in presence of O. tyrtaeum, but did not respond to the addition of the rye leaves. In addition, the bacterial community in treatments with O. tyrtaeum differed from that without earthworms and shifted towards an increased dominance of Gram-negative bacteria. The results indicate that litter-decomposing fungi translocate litter-derived carbon via their mycelial network in to the upper mineral soil. Endogeic earthworms decrease fungal biomass by grazing and disruption of fungal hyphae thereby counteracting the fungal-mediated translocation of carbon in soils. (c) 2007 Elsevier Ltd.
