Abstract/Summary

Purpose This study aims to investigate effect of sieving on ex-situ soil respiration (CO2 flux) measurements from different land use types. Methods We collected soils (0 – 10 cm) from arable, grassland and woodland sites, allocated them to either sieved (4mm mesh, freshly sieved) or intact core treatments and incubated them in gas-tight jars for 40 days at 10ºC. Headspace gas was collected on day 1, 3, 17, 24, 31 and 38 and CO2 analysed. Results Our results showed that sieving (4 mm) did not significantly influence soil respiration measurements, probably because micro aggregates (<0.25 mm) remain intact after sieving. However, soils collected from grassland soil released more CO2 compared to those collected from woodland and arable soils, irrespective of sieving treatments. The higher CO2 from grassland soil compared to woodland and arable soils was attributed to differences in the water holding capacity and the quantity and stoichiometry of the organic matter between the three soils. Conclusion We conclude that soils sieved prior to ex-situ respiration experiments provides realistic respiration measurements. This finding lends support to soil scientists planning a sampling strategy that better represents the inhomogeneity of field conditions by pooling, homogenising, and sieving samples, without fear of obtaining unrepresentative CO2 flux measurements caused by the disruption of soil architecture.
