Tree plantations are an important component of tropical landscapes, providing wood, fuel, and perhaps carbon (C) sequestration. Primary production in wet tropical plantations is typically nutrient limited. In some Hawaiian Eucalyptus plantations, nitrogen (N) limitations to production are alleviated by intercropping N-fixing Albizia trees that may decrease available phosphorus (P). Thus, sustainable productivity and C sequestration may depend on species composition. We measured soil N and P availability and ecosystem N and C sequestration in a 17-yr-old replicated replacement series of Eucalyptus and Albizia in Hawaii. Species composition included pure plots of each species and four proportions of mixtures. Soil N availability increased with the proportion of Albizia in the plot, but soil P availability declined. Aboveground tree C accumulation showed a synergistic response to increasing percentage of Albizia, with the mixed stands having more tree C than pure stands of Eucalyptus or Albizia. In the top 50 cm of soil, total N and C increased linearly with percentage of Albizia. Stands with the highest percentage of Albizia had 230 g/m2 more soil N and 2000 g/m2 more soil C than stands without Albizia. Stable C isotope analyses showed that increased soil C resulted from differences in both tree-derived C and "old" sugarcane-derived C. Deeper soil C (50-100 cm) was a substantial fraction (0.36) of total soil C but did not vary among treatments. Our results demonstrate that tree species effects on nutrient and C dynamics are not as simple as monocultures suggest. Mixedspecies afforestation increased tree and soil C accrual over 17 years, and N inputs may increase soil C storage by decreasing decomposition.

“…Similar increases in nutrient cycling or N and P availability in N-fixing species have been found in other studies, both in plantations and native forests, including some mixed-species stands containing Eucalyptus (Binkley et al, 2000;May and Attiwill, 2003). It is important to note that increases in N cycling and the availability of N-fixing plants can influence the availability of other nutrients (Binkley et al, 2000;Kaye et al, 2000).

Rana et al (2007) nutrimentos (Binkley et al, 2000;Kaye et al, 2000). Rana et al (2007), expresan en un estudio del aporte de nutrimentos en plantaciones forestales sobre suelos sódicos al norte de la India, que el mayor aporte de N anual a través de la hojarasca correspondió a C. Richards et al (2010) informan que la producción de hojarasca y su posterior descomposición se vincula a los procesos que ocurren por encima y por debajo de suelo, los cuales determinan la productividad del árbol y del rodal; afirman que si las tasas de descomposición son constantes o aumentan, una producción mayor de hojarasca o cambios en el ritmo de las aportaciones en plantaciones mixtas podrían aumentar el suministro de nutrimentos al suelo, en comparación con los monocultivos e ilustran con un ejemplo de un experimento en árboles tropicales, en el cual la producción de la madera y hojarasca sobre el suelo fueron superiores en las mezclas de tres especies que en sus correspondientes monocultivos, debido a que las interacciones interespecíficas influyen en el crecimiento y la captura de nutrimentos mientras que las tasas de descomposición de hojarasca no fueron afectadas.…”

Carbon Stocks in Mined Area Reclaimed by Leguminous Trees and Sludge

“…The increase in C concentration and stocks appears to modulate the phosphorus dynamic in this degraded area. Efforts in terms of studies are recommended in this direction as C (and N) contents in soils could increase in detriment of P availability, depending on the mixture and structure of the forest planted (Kaye et al, 2000;Koutika et al, 2014).…”

“…Resource use efficiency may increase with resource use (Binkley et al, 2004) and mixed species plantations may also use resources more efficiently through facilitation mechanisms (Kelty, 2006). An example is planting N 2 -fixing tree species with a non-N 2 -fixing tree species, which may enhance N soil availability and increase the growth of the non-N 2 -fixing tree (Kaye et al, 2000;Richards et al, 2010). Several studies have shown that N-fixing species may have a positive effect on the overall productivity of mixed forest plantations (e.g., Richards et al, 2010;Forrester et al, 2010Binkley et al, 2003.…”
