Brief description

Spectral chemistry (processed spectra and where relevant integrated regions), elemental analysis and respiration characteristics of 85 organic amendments incubated in a sand matrix. The samples comprise 50 composts, six manures, 10 plant residues and 19 biosolids.

Samples were analysed by nuclear magnetic resonance (NMR), mid-infrared (MIR) and near-infrared (NIR) spectroscopy, as well as elemental analysis by dry combustion.

Incubations were conducted in a sand matrix under controlled conditions for 18 months, with CO2 levels monitored and a double first-order exponential decay model fitted to produce four parameters (size of the fast [Cf] and slow [Cs] pools, and their modelled turnover rates [f and s respectively]).

Collectively, these data were generated to understand how the chemical composition of organic amendments affects their decomposability.
