Samples were prepared using the method outlined by ref. 28 and analysed using a Finnigan Element XR high-resolution inductively coupled plasma mass spectrometer (Cardiff University).
Collectors, 102 mm in diameter and 200 mm in height, were set in the field according to the method outlined by ASAE [(2001). American Society of Agricultural Engineers.
We use the method outlined by Cloutis et al. [Cloutis, E.A., Gaffey, M.J., Jackowski, T.L. Calibrations of phase abundance, composition, and particle size distribution for olivine-orthopyroxene mixtures from reflectance spectra. J. Geophys. Res.
The computational method outlined by the Intergovernmental Panel on Climate Change (IPCC) has been used to estimate SOC stock changes at the regional scale in several studies, including a recent study considering five contrasting eco regions.
The composition was found to consist primarily of quartz grains (Figure 2b) with a void ratio of 44% (determined using the method outlined by Gibbons [7]).
Here, the hydrate saturation and its volume fraction in the sediment are estimated following the method outlined by Matsumoto and Borowski (2000).
Forest floor samples included all organic material above the mineral soil, and were collected on a systematic grid across the plot using a 25 cm2 sampling frame following the general method outlined by Harmon et al. [28].
The Se-rich wheat and paddy straw was collected from Jainpur (31°13′N, 76°21′E, Nawanshahr Hoshiarpur region, Punjab), India, for cultivation of these mushrooms following method outlined by Punjab Agricultural University India (Khanna 2003).
Relative quantification and standard deviation calculations were derived by the comparative method (outlined by Applied Biosystems).
Relative quantification of all targets was calculated by the comparative cycle threshold method outlined by the manufacturer (User Bulletin No. 2; Applied Biosystems).
