abstract = {Litterfall evaluation and the effects caused by forestry practices provide valuable
information on nutrient-cycle dynamics in managed forests. So far, most
of the studies have focused on leaf-fall, omitting other litterfall fractions that
can be also relevant for forest and soil modelling in a global change context.
With this aim the miscellaneous fraction was quantified in a Pinus halepensis
afforestation in the semiarid SE of Spain five years after four different thinning
regimes were applied (T75: 75% of mean basal area removed; T60: 60%;
T48: 48%; and T0: no thinning). Concentrations and pools (kg ha-1) of carbon
and nutrients in the miscellanea fraction were monthly analysed for C and N
(June 2010-May 2013), and for P, K, Na, Ca, Mg, Fe, Zn, and Mn (June 2011-
May 2013). No differences in concentrations of carbon and nutrients were
found among treatments with the exception of N, which showed significant
differences between T75 and T60 plots. For pools, a high variability was found
over time with maximum C and N pools found during spring, likely reflecting
the influence of Thaumetopoea pityocampa attacks. Thinning affected C, N,
Mn, and Zn pools in 2011-2012 period, and P, K, Ca, Mg, Mn, Fe, and Zn pools
in 2012-2013. Significant differences were mainly found between the most intensive
treatment (T75) and unthinned plots (T0). The percentage of annual
mean C and nutrient pools in miscellanea showed the importance of its monitoring,
with pools that represented from 43.0% to 57.9% of the total litterfall
for C (278.81-746.01 kg ha-1 yr-1), N (4.18-10.44 kg ha-1 yr-1), and P (0.37-1.43
kg ha-1 yr-1). Our results stress the high relevance of miscellany monitoring in
order to gain a better understanding of nutrient cycles in forest ecosystems.},
