abstract = {Losses of soil organic carbon often occur because of
intensive agricultural practices that lead to removal of
organic carbon following harvest production and to
insufficient inputs. Organic amendments can be very
appropriate for enhancing organic carbon content in very
stressed agricultural soils. By enhancing soil organic
matter, they generally play an important role in
environmental matrices due to their capacity in retaining
water and in enhancing nutrient availability to plants.
Therefore, understanding the mechanisms by which organic
amendments interact with other chemicals in the environment
is of paramount importance. The attention was focused on
farms near Sele river (Campania region, Italy), an area
characterized by intensive agriculture. Two farms, with
contrasting geopedologic properties (clay vs. sandy), were
selected in order to study the effect of different doses of
organic amendments containing compost from municipal solid
wastes and wood-wastes (scraps of poplars pruning) at
different ratios. The organic fractions were extracted from
soil, after one and twelve months from amendment, and were
analysed in order to establish their elemental composition
and properties by FTIR, CPMAS 13C NMR spectroscopy and
FFC-NMR relaxometry. Results showed an important role of
soil geopedologic characteristics and experimental time in
the evolution of humic acids. In less aerobic conditions as
occurs in clay soils, organic matter was more stable, rich
in carbonyl groups belonging to aldehydes and ketones,
whereas under more aerobic conditions, occurring in sandy
soils, organic matter had undergone a faster degradation,
due to oxidative conditions and more intensive microbial
activity.},
