“…In contrast to previous work solely determining greenhouse gas emissions and/or the response of the soil microbial community composition to (in)organic nutrient amendments (e.g., Huang et al, 2004;Ceja-Navarro et al, 2010;Serrano-Silva et al, 2011;Galvez et al, 2012;Odlare et al, 2012;Li et al, 2013;Sengupta & Dick, 2015), common wheat, a cereal grain crop, was planted in the mesocosms to assess crop growth and productivity (aboveground dry weight biomass) after residue amendments. Amendments with sewage sludge and aquatic plant material yielded higher crop biomass in both soils, in line with the higher N (NO x and NH 4 + ) and P concentrations in the residue-amended soils prior to wheat addition (Ho et al, 2015b).…”

With the projected rise in the global human population, agriculture intensification and land‐use conversion to arable fields is anticipated to meet the food and bio‐energy demand to sustain a growing population. Moving towards a circular economy, agricultural intensification results in the increased re‐investment of bio‐based residues in agricultural soils, with consequences for microbially mediated greenhouse gas (GHG) emission, as well as other aspects of soil functioning. To date, systematic studies to address the impact of bio‐based residue amendment on the GHG balance, including the soil microorganisms, and nutrient transformation in agricultural soils are scarce. Here, we assess the global warming potential (GWP) of in situ GHG (i.e., CO2, CH4, and N2O) fluxes after application of six bio‐based residues with broad C : N ratios (5–521) in two agricultural soils (sandy loam and clay; representative of vast production areas in north‐western Europe). We relate the GHG emission to the decomposability of the residues in a litter bag assay and determined the effects of residue input on crop (common wheat) growth after incubation. The shift in the bacterial community composition and abundance was monitored using IonTorrentTM sequencing and qPCR, respectively, by targeting the 16S rRNA gene. The decomposability of the residues, independent of C : N ratio, was proportional to the GWP derived from the GHG emitted. The soils harbored distinct bacterial communities, but responded similarly to the residue amendments, because both soils exhibited the highest mean GWP after addition of the same residues (sewage sludge, aquatic plant material, and compressed beet leaves). Our results question the extent of using the C : N ratio alone to predict residue‐induced response in GHG emission. Taken together, we show that although soil properties strongly affect the bacterial community composition, microbially mediated GHG emission is residue dependent.

“…Parte das emissões iniciais de CO 2 relacionadas com a adição de DLS ao solo ocorrem devido à atividade microbiana dos organismos presentes no próprio dejeto. Odlare et al (2012) relatam que a ocorrência de picos de emissões iniciais pode ser relacionada aos constituintes de fácil decomposição presentes nos dejetos.…”

Cultivation of plants, such as castor bean (Ricinus communis L.) or Jatropha curcas L. is set to increase in future as their seeds are used to extract oil for biofuel production. Ricinus communis seed cake (RSC) and J. curcas seed cake (JSC) were applied to soil cultivated with wheat (Triticum spp. L.) while plant growth and emissions of the greenhouse gases, CO 2 , CH 4 and N 2 O were monitored. Application of RSC or JSC had no significant effect development of the wheat plants. Emissions of CO 2 and N 2 O increased in soil amended with JSC or RSC, especially when larger amounts were applied, but had no effect on emissions of CH 4 . It was found that application of seed cakes increased emissions of CO 2 and N 2 O, but did not stimulate plant growth.Keywords: biofuel; decomposition of seed cake; emissions of CO 2 , CH 4 and N 2 O; mineral N; soil characteristics V.M. Ruíz-Valdiviezo, Á. Aguilar-Chávez and M.R. Cárdenas-Aquino contributed equally to the experiment.
