TL;DR: In this paper, the authors investigated the usefulness of near infrared (NIR) reflectance spectroscopy in determining: (i) various constituents (total N, total C, active N, biomass and mineralisable N, and pH), (ii) parameters (soil source, depth from which sample was obtained, type of tillage used) and (iii) rate of application of NH4NO3 fertiliser) of low organic matter soils.

TL;DR: In this paper, the authors collected 120 bulk soil samples (BS) from long-term tillage experiments and areas covered by secondary natural forest in the Brazilian savanna region (Cerrado) at Santo Antonio de Goias, and southern Atlantic forest region at Londrina.

TL;DR: In this article, a study was conducted to examine C and N mineralization characteristics of manure components from feeds (immature and mature alfalfa and orchardgrass, soybean meal, roasted soybeans), forage cell walls (acid detergent fiber [ADF], simple N compounds (urea, amino acids and peptides), and non-ietary metabolic components (ruminal bacteria and colonic cells).

TL;DR: Results indicate that DRIFTS may be useful for accurate predictions of metals if samples originate from one region, and mid-infrared spectroscopy markedly outperformed NIRS.

TL;DR: In this article, the authors performed mid-infrared (midIR) spectral interpretation of fractionated fresh and incubated soils to determine changes in soil organic matter (SOM) chemistry during incubation.
