We assessed the relationship between CO₂, CH₄ and N₂O fluxes and soil thermal conductivity (K), resistivity (R) and diffusivity (D). The study was conducted in 2004 and 2005 in a permanent pasture at Lincoln University's Washington Carver Farm. Sixteen static and vented chambers were installed permanently in a 400 by 400 m plot at 100 m spacing since 2003. Soil samples collection for analysis of chemical and physical properties and direct measurement of soil thermal properties were conducted yearly from June to December. A KD2 probe was used to measure thermal properties at 0.06 m depth inside and near each chamber. Soil air samples for determinations of CO₂, CH₄ and N₂O were also collected when measuring soil thermal properties. Analysis of CO₂, CH₄ and N₂O from air samples was done within two hours of sampling at Dickinson Research Center with a Shimadzu Greenhouse Gas GC-14. Integrated fluxes for 2004 and 2005 showed that CO₂ ranged from 17.25 to 336.67 mg CO₂-C m^-2 h^-1, CH₄ uptake from 59.26 to 107.20 ug CH₄–C m^-2 h^-1 and N₂O from –14.58 to 96.04 ug N₂O-N m^-2 h^-1. Except for N₂O which only correlated with K and D, CO₂ and N₂O fluxes were either linearly, exponentially or quadratically correlated with K, R, D and soil temperature with coefficient of correlation (r) ranging from 0.35 to 0.80. In addition, CO₂, N₂O and CH₄ also correlated among themselves with (r) ranging from 0.40 to 0.90. These results suggest that soil thermal properties may be important factors in controlling greenhouse gas fluxes from soils to the atmosphere.
