“…In Europe, North America and Russia large areas are being remodelled into fresh new forests that can act as a carbon sink and diminish global carbon levels (Pérez-Cruzado et al, 2014). For this reason, afforestation is one of the most credited strategies according to the Kyoto Protocol (Cerli et al, 2008;Savy, Nebbioso, Cóndor, & Vitullo, 2012). In Spain, an active afforestation programme was adopted in the 1950s where the soils were severely eroded (FAO, 2015) after widespread abandonment of arable land.…”

Afforestation is an important strategy that can decrease atmospheric carbon by sequestering carbon in biomass and soil. In Spain, an active afforestation programme was adopted in the 1950s when the soil was severely eroded after widespread abandonment of arable land. The Araguás catchment (Central Spanish Pyrenees) is a good example of this programme because it was afforested with both Pinus sylvestris L. (PS) and Pinus nigra J.F.Arnold (PN). The soil organic carbon (SOC) stock and lignin content (based on the vanillyl, syringyl and cinnamyl contents) of these afforested soils were examined and compared to those of bare soil, secondary succession and meadow soils. Both the SOC stock and lignin content were used to evaluate the effects of land‐use changes on soil. Curie‐point pyrolysis with tetramethylammonium hydroxide was used to assess the lignin content. In the bare soil, there was none of the lignin compounds. The largest SOC stock and lignin content occurred under PN and secondary succession sites. A decreasing trend for the lignin content, related to the limited organic matter input and the longer degradation period, was observed at deeper horizons in all soils except meadows. These meadow soils also showed increased SOC stocks in deeper horizons. Land abandonment reduced the SOC stock although no significant differences were observed in the organic carbon incorporation assessed through lignin content (and if this was so it was restricted to the top centimetre or so). According to the results, PN was the best afforestation practice for increasing SOC stock and lignin content in soil. Pinus sylvestris afforestation was less successful than secondary succession at increasing SOC sequestration and lignin content. Highlights Effects of long‐term afforestation and land abandonment assessed in Mediterranean humid mountain soils. Soil organic carbon (SOC) stock and lignin content were used as indicators. Bare soil had the smallest SOC stock and lignin content. Afforestation with Pinus nigra was the best practice, increasing SOC stock and lignin content.

“…The use of fossil fuels for producing energy and chemicals has not only resulted in a significant increase in global warming but has also resulted in detrimental impacts on ecosystem properties, biodiversity, and plant growth. , These negative effects, together with the predicted fossil fuel depletion over the next few decades, has led scientists to look for alternative solutions to satisfy the needs of energy and polymers. One of those is based on the exploitation of carbohydrates obtained from nonfood crops during biorefineries processes. , Regardless of the employed extracting procedures, biorefinery processes leave lignin-rich byproducts as wastes, which are usually disposed of or burned as an energy supply for the industrial plant .…”

The development of soil microbiota and the chemical composition of soil organic matter (SOM) were studied in a 180 day incubation experiment upon addition of a characterized lignocellulosic biorefinery residue (BYP) at two different rates. The microbial growth was studied by PLFA analysis after 30, 60, and 180 days, while SOM molecular composition was assessed by thermochemolysis at the end of the trial. Soil amendments with BYP induced a well differentiated microbial community. However, the overall microbial development significantly decreased over the experimental time due to a lesser availability of decomposable C to microorganisms. The reduced C accessibility was related to the progressively higher SOM recalcitrance with increasing BYP rates and was attributed to selective accumulation into the stable SOM fraction of hydrophobic compounds which prevented further BYP mineralization by protecting BYP from microbial activity. Our findings indicate that amendments with lignin-rich residues from biorefinery processes may promote the stabilization of humified molecules in soils, thus leading to a net C accumulation in soils.
