“…and white faveira (Schizolobium amazonicum Huber ex Ducke), were selected for study based on the criteria of uniform size and individual health within the same species (heights of 40 cm for I. edulis, 35 cm for D. odorata and 30 cm for S. amazonicum). Among the three species selected for the present study, I. edulis, an early successional species, is the only N 2 -fixing species and is primarily used in agroforestry systems and mixed-species plantations as a facilitative species [23]. D. odorata has great potential for use in forest restoration because it is a late successional species that is well adapted to degraded areas and also produces high-quality hardwood [24].…”

Abstract:Background: Choosing the correct species and fertilization treatments is a determining factor in the success of forest restoration. Methods: A field study was conducted in a degraded area near the Balbina hydroelectric dam in Amazonas State (AM), Brazil, to evaluate two hypotheses: (i) leguminous tree species exhibit differences in growth, leaf nutrient content, and photosynthetic nutrient use efficiencies; and (ii) differences in these characteristics depend on the fertilization treatments to which the species have been subjected. Dipteryx odorata, Inga edulis and Schizolobium amazonicum were subjected to the following treatments: (T1) unfertilized control; (T2) post-planting chemical fertilization; (T3) post-planting organic fertilization and (T4) combined chemical and organic post-planting fertilization. Results: In general, I. edulis had the highest absolute growth rate of biomass under all of the fertilization treatments. I. edulis and S. amazonicum showed the highest growth rates under the T4 treatment. D. odorata showed the greatest responses under the T2 and T4 treatments. Native leguminous trees with higher photosynthetic performance and better nutrient use efficiency exhibited greater growth and biomass production. Conclusion: The results suggest that an adequate balance between leguminous species selection and fertilization will aid in the success of forest restoration in Amazonia.

“…is native or naturalized throughout South and Central America and is commonly used as a shade tree in coffee and cocoa plantations. It improves degraded soil by increasing soil nitrogen 3 and is used in Cameroon to increase soil fertility. It produced a very high amount of biomass, 61 tons ha −1 within 20 months, 4,5 and is known by the population for its sweet fruits and as supplier of fire wood.…”

“…The distribution of I. edulis has statistically significant relationship with high levels of exchangeable bases, larger amount of leaf litter and larger amounts of clay; namely microsites with better soil conditions for agriculture. This should not only respond to the selection of the site but could be related to the contribution of species to the system, as demonstrated by Nichols and Carpenter (2006) in agroforestry plots. Regarding the spatial distribution of D. rigida, P. Caimito, T. grandiflorum, A. Occidentale and P. cecropifolia, factors that showed significant statistics were related to the distribution of decaying woody biomass, percentage of leaf litter, percentage of clay in soil and levels in the amount of nutrients (Ca +2 , Mg +2 , K +, P).…”

RESUMENEl sistema de agricultura migratoria, determinante en la soberanía alimentaria de los indígenas Piaroa en la orinoquia venezolana, es una actividad antropocéntrica que ha permitido conservar la dinámica del bosque húmedo tropical. En la actualidad, los cambios ocasionados por los procesos de globalización amenazan la sostenibilidad del sistema. Por tal motivo, el estudio a detalle de su funcionamiento es preponderante para la toma de decisiones referentes al manejo del bosque. Esta investigación planteó determinar la relación existente de las especies cultivadas con algunas propiedades y características físicas y químicas del suelo, en la etapa de siembra. Para ello, 40 unidades de muestreo (suelo y vegetación) se ubicaron en diferentes conucos Piaroa, en dos periodos distintos después de la quema. Con base en los datos de campo, se desarrolló un modelo para explicar la distribución espacial de cada una de las especies cultivadas a partir de las características edáficas. El modelo aplicado presentó distintas respuestas en función de las especies cultivadas por los indígenas. Sin embargo, explica la selección de micrositios para la siembra a través de las propiedades físicas del suelo, la distribución de la hojarasca y la distribución de la biomasa después de la tumba y quema en el conuco. ABSTRACTShifting cultivation system, factor in the food sovereignty of the Piaroa indigenous in the Venezuelan Orinoquia, is an anthropocentric activity that has preserved the dynamics of tropical rainforest. Today, the changes caused by globalization processes threaten the sustainability of the system. Therefore, studying in detail the operation of the systems is fundamental for making decisions regarding the management of the tropical forest. This study proposed to determine the relationship between crop species and soil characteristics at the stage of sowing. Therefore, 40 sampling units (soil and vegetation) were placed in 4 Piaroa conucos, in two different periods of time after burning (0 to 2 and 2 to 4 years). Based on the field data, a model was developed to explain the spatial distribution of each grown species according to the soil characteristics. The model used showed different responses depending on the species grown by the Piaroa indigenous. However, this model explains the selection of microsites for sowing through soil physical properties, leaf litter distribution and biomass distribution after the felling and burning stage in the conuco.PALABRAS CLAVE: Sistema de cultivo originario, suelos, especies cultivadas, siembra.
