“…Similar results were reported by Souza et al, (2007) found that less root development of leucaena, which shows greater difficulty in establishing this species in soils of forest areas. The development of roots of leucaena is sensitive to soil acidity and the aluminum content, as noted by Vale et al, (1996) and Silva et al, (2009), which may explain the poor development of roots, a characteristic found for samples of forest soil used in the experiment. In both species were observed nodulation in all soils of the areas studied, with the best nodule formation in these species occurring in soil cultivation 1 and 4.…”

Experiments were performed in a greenhouse to evaluate the effect of natural nodulation in the development of Pacara Earpod Tree (Enterolobium contorsiliquum) and Leucaena (Leucaena leucocephala) is soil with different uses in Tocantins. We used three soil samples of woods, cultivated areas four and in a degraded area, in pots in a completely randomized design with four replications. In both species nodulation was observed in all soils studies areas with better nodulation occurring in soil cultivation, providing a higher accumulation of biomass. Soil from the degraded area the two species showed nodule number and biomass of nodules significant, with potential for use in disturbed areas, with characteristics of degraded soils.

“…The results of nodulation contrasted with data from other studies that compared the ability of two legume nodulation (Souza et al, 2007), since in the present study, there was a higher nodulation of leucaena. The species showed high specificity to the microsymbionts (Silva et al, 2009) and this fact may be related to native rhizobial populations prevailing in the areas and the ability of these native rhizobia to establish effective symbiotic associations.…”

The growth of tree legumes in degraded areas must be preceded by assessments of nodulation ability of naturally established rhizobia populations since such information contributes to defining the species which can be planted for recovering disturbed areas. The aim of this study was to evaluate the growth and natural nodulation of "sabiá" (Mimosa caesalpiniifolia Benth.) and leucaena (Leucaena leucocephala (Lam.) de Wit.) in soils of the Brazilian semiarid area under different systems of land use: native vegetation (locally called caatinga) and areas with different agricultural systems (a monocrop system and an intercropping with various species). For each species, a greenhouse experiment in randomized block design was realized, using soils of different types (Luvisol and Ultisol), with 4 replicates. The results evidentiate significant differences in the evaluated growth characteristics (height, leaflet number and shoot diameter) of M. caesalpiniifolia, that have displayed lower plant growth when cultivated in the Luvisol under conventional system. Plant growth, nodulation and total N accumulation in both seedling tree legumes increased in Ultisol under the different systems of land use. L. leucocephala showed higher potential of biological nitrogen fixation and nodulation effectiveness promoted by indigenous rhizobia.

“…Jesus et al (2014) também verificaram, em estudo conduzido no Sudoeste do Piauí, relação direta entre a fertilidade do solo e nodulação em mudas de tamboril, sendo esta superior em solos de maior fertilidade. Resultados semelhantes foram reportados por Silva et al (2009), em experimento com as leguminosas leucena, bordão-de-velho e feijão-caupi cultivadas em solos de Cerrado sob diferentes sistemas…”

O objetivo deste trabalho foi avaliar o efeito de diferentes sistemas de uso dos solos do Sudoeste do Piauí no crescimento e nodulação natural de mudas de tamboril [Enterolobium contortisiliquum (Vell) Morong]. O experimento foi conduzido em viveiro da Universidade Federal do Piauí, em Bom Jesus, PI. O delineamento experimental foi inteiramente casualizado com dez repetições. Os tratamentos foram: quatro sistemas de uso do solo (duas áreas de mata nativa, uma área de pastagem e outra de agricultura). Aos 85 dias as mudas foram coletadas e avaliaram-se a altura (H), o diâmetro do colo (DC), o número (NN) e a matéria fresca de nódulos (MFN), as matérias secas da parte aérea (MSPA), das raízes (MSR) e total (MST), a relação entre matéria seca da parte aérea sobre a das raízes (MSPA/MSR), o índice de qualidade de Dickson (IQD) e o acúmulo de nitrogênio na parte aérea (ANPA). Ocorreu nodulação em todos os sistemas de uso dos solos. As mudas cultivadas em solos de áreas agrícolas e de pastagem apresentaram maior destaque quanto à nodulação, H, DC, MSPA e ANPA, do que as áreas de mata nativa.
