“…Ludvichak et al (2016) also with the same species found 1253 mg kg -1 at 5 years. According to Jiménez and Navarro (2015), this decreasing trend as the stand ages has also been observed in a Pinus plantation, 5 years after thinning in semiarid climate. For the authors, the decline in Mn concentration in the needles is due to the maturity of the stand where the element ends up being partially translocated.…”

The evaluation of litterfall and nutrient return is important for understanding the dynamics of nutrient cycling. Although required in smaller quantities by plants, micronutrients have unique importance in biogeochemical regulation. The objective of the present study was to quantify the litterfall and the concentration of micronutrients in the different fractions and seasons of the year in Eucalyptus dunnii stand. Four plots of 20 m x 21 m were demarcated. The collection of leaf litter, twigs (diameter <0.5 cm) and miscellaneous resulted in the installation of 4 collectors with an area of 0.5 m² in each plot. For the quantification of the thick branches fraction (diameter> 0.5 cm), four useful areas of medium-diameter trees were demarcated in each plot. The leaf fraction represented 59% of litterfall and the transfer order was Mn> Fe> B> Zn> Cu, totaling 8.04 kg ha-1. The leaf fraction presented the highest concentrations for B and Mn. The litterfall was seasonal with summer and spring differing statistically from winter and the temperature variable explains the deposition pattern of the same.

“…Ca concentration was lower in green needles than that in the litter, while Mg concentration was the opposite [ 55 ]. Elevated Ca and Mg concentrations for P. halepensis were found in winter [ 56 ]. In addition to tree age and needle development stage, environmental factors also affected the nutrient levels of these two elements.…”

Inter- and Intra-Population Variation of Foliage Calcium and Magnesium in Two Chinese Pine Species

Calcium and magnesium are major nutrient elements of plants, and both play an important role in plant growth and development. Pinus massoniana and P. hwangshanensis are important afforestation tree species in barren mountains in China. However, observation and research on calcium and magnesium nutrition of dominant forest species in China are still limited. This study determined the concentration of calcium and magnesium in needles for two species from five sites in East China by inductively coupled plasma optical emission spectrometry (ICP-OES). We then explored the inter- and intra-population variation pattern of calcium and magnesium and their relationship with environmental factors. There were significant differences in traits among populations. The strongest factors, which impacted the variation of calcium and magnesium concentration, were elevation and individual differences, respectively. Element concentration was correlated to environmental factors such as longitude, latitude, elevation, and mean annual temperature. The results of this study can be helpful for a better understanding of tree growth, population survival, and forest succession.

“…In our case, differences between thinning intensities were also found in N-concentration dynamics over time, which trends may indicate some points in the life cycle of the pine processionary (Thaumetopoea pityocampa). Indeed, nest and frass from insects contained less N than did the green needles on which they feed, according to the foliar nutrient concentrations reported by Jiménez & Navarro (2015). During spring, the N concentration could be diluted due to other fallen materials poor in N. In addition, dynamics in N and C concentration in the miscellany could also reflect remains falling from another pest and pine organs (buds, seeds, flowers, pollen, etc.)…”

“…In previous research, we investigated the effect of four thinning intensities on P. halepensis afforestation in the SE Spain over three years at different levels. Firstly, it was reported the thinning effects on foliar carbon and nutrient concentrations (Jiménez & Navarro 2015). Secondly, litterfall production and how it was affected by thinning were specified for needles, twigs, woody material, and miscellaneous fractions .…”

Biogeosciences and Forestry Biogeosciences and Forestry Carbon and nutrient contents in the miscellaneous fraction of litterfall under different thinning intensities in a semiarid Pinus halepensis afforestation Carmen Segura (1) , Emilia Fernández-Ondoño (1) , M Noelia Jiménez (2) , Francisco B Navarro (3) 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
