“…This could be attributed to higher coarse and fine root biomass incorporated by D. hamiltonii. Contrary to this, the lowest active carbon pool was observed under D. asper, which probably contributed to the lowest biomass of coarse and fine roots (Kaushal et al, 2020b;Kumar et al, 2020b). D. hamiltonii is a species of the sub-tropical to subtemperate region growing up to an elevation of 1500 m and prefer medium-textured slightly acidic soil (pH 5-6).…”

“…This characteristic of bamboo makes it a highly effective species for sequestration of soil C ( Nath et al., 2015a , Nath et al., 2015b ). The higher carbon pools under various species of bamboo may be due to the continuous litter addition and the development of ample fine root biomass by the different species of bamboos ( Kaushal et al., 2020a , b ). The greater percentage of C in the upper soil layer (0–15 cm) could be attributed to the presence of litter debris in this layer; which facilitates the availability and supplying of mineralizable and easily hydrolysable carbon leading to higher activity and population of microbes ( Kaur et al., 2008 ; Benbi et al., 2015 ).…”

“…Bulk soil samples were collected from each replication of the six bamboo species as well as the open plot (fallow) without bamboo during the year 2019 (fourteen years after the establishment of the bamboo plantation). Soil samples were collected from two soil depths 0–15 cm and 15–30 cm with the help of an auger as majority of roots (fine root and coarse roots) in bamboo species are confined to 0–30 cm soil depth ( Kaushal et al., 2020b ). For each plot, rhizosphere soil samples were collected from six random locations under the canopy and mixed to obtain a composite sample of about 1000 g. The soil samples were air-dried in shade, ground and sieved for the analysis of various C fractions.…”

Carbon fractions under different bamboo species viz ., Bambusa balcooa, Bambusa bambos, Bambusa nutans, Dendrocalamus hamiltonii, Dendrocalamus asper and Dendrocalamus strictus were evaluated to understand the potential of these different bamboo species in soil rehabilitation in Himalayan foothills. The highest accumulation of the different carbon fractions likes very labile (6.12 mg g −1 ), less labile (2.55 mg g −1 ) and non-labile (11.40 mg g −1 ) was observed under D. hamiltonii, while highest labile fraction (3.17 mg g −1 ) was recorded under D. strictus . The highest active (8.85 mg g −1 ) and passive pool (13.95 mg g −1 ) were recorded under D. hamiltonii . Higher carbon management index (CMI) was obtained under D. hamiltonii (186.04) which was comparable with D. strictus (182.66) and B. nutans (179.24). Among all the six species, D. hamiltonii had the highest buildup of active and passive pool in both the soil depths. Bamboo plantations irrespective of the different species helped in enhancing the SOC fraction and enhanced C buildup in the soil in comparison to the open fallow land and holds potential in combating the problems of land degradation and soil rehabilitation.

“…It is worth noting that the vigorous growth of trees may lead to insufficient soil water and nutrient supply (Kaushal et al, 2020). As root competition is also associated with plant adaptation to the environment, plants with vigorous roots have stronger root scale plasticity for higher levels of nutrient acquisition, usually exhibiting high competitiveness and influencing the growth and development of other plants (Sarto et al, 2020).…”

Agroforestry, as a phytoremediation measure, shows great potential for mitigating land degradation by constructing multidimensional and efficient agroforestry composite systems through regulating the microenvironment of agroforestry sites and improving soil properties. However, the effects of different agroforestry composite management modes on saline soils and the interactions between soil–plant systems under salt stress conditions in coastal areas remain largely unexplored. In this study, two salt‐tolerant tree species (Sapium sebiferum (Linn.) Roxb and Zelkova serrata (Thunb.) Makino) and four crop species (Medicago sativa, Sesbania cannabina, Sorghum bicolour, and Avena sativa) were selected for intercropping in eight composite patterns via field experiments, with dynamics of soil physicochemical properties and crop photosynthesis observed. The results showed that treatments intercropped with M. sativa had the highest soil bulk density range (1.41–1.48 g cm−3). The dynamics of topsoil (0–10 cm) chemical properties showed similar change patterns among treatments, whereas those of the 10–40 cm soil chemical properties (especially soil pH, soil organic matter [SOM], and total nitrogen [TN]) showed heterogeneity. Moreover, planting S. sebiferum (L.) Roxb under the same crop conditions increased tree height growth rate and survival rate by 75%–114% and 14%–33%, respectively, relative to planting Z. serrata (T.) Makino. Furthermore, a significant negative correlation was observed between soil moisture with crop intercellular CO2 concentration (λ = −0.77), while significant positive correlations were found between crop net photosynthetic rate (Pn) with soil TN (λ = 0.71), as well as SOM with atmospheric CO2 content (λ = 0.72). Structural equation modeling showed significant direct effects between tree height growth rate with soil TN and SOM. Soil moisture (λ = 0.47) and tree height growth rate (λ = 0.53) were dominant drivers of crop Pn. Our findings provide useful information for the prevention of coastal saline soil degradation and sustainable development of agroforestry.

“…Bamboo has also been proven to address many global challenges and contributes to the following United Nations Sustainable Development Goals: SDG 1 (no poverty), 7 (affordable and clean energy), 11 (sustainable and resilient housing), 12 (efficient use of resources), 13 (address climate change), and 15 (life on land) (Bau & Trinh, 2019; Ekhuemelo et al., 2018; Kaushal et al., 2018; Yuen, Fung, & Ziegler, 2017). Due to its potential for water recharge and mitigation soil erosion, bamboo also provides an opportunity for watershed development and restoration of degraded areas (Kaushal et al., 2019, 2020). Furthermore, bamboo is a fodder for livestock and food for humans contributing to ensuring food security (Andriarimalala, Kpomasse, Salgado, Ralisoa, & Durai, 2019; Choudhury, Sahu, & Sharma, 2012; Halvorson, Cassida, Turner, & Belesky, 2011; Mulatu, Bahiru, Kidane, Getahun, & Belay, 2019; Nongdam & Tikendra, 2014).…”

Bamboo, a member of subfamily Bambusoideae in the grass family (Poaceae), is one of the most important nontimber forest resources and a potential alternative to wood and wood products. Ethiopian lowland bamboo ( Oxytenanthera abyssinica ) is an economically and ecologically important species which accounts about 85% of total bamboo coverage in the country. This species is experiencing population decline due to a number of anthropogenic factors. As a foundation step, genetic diversity, population structure, and gene flow analysis of various O. abyssinica populations found in Ethiopia are studied using inter‐simple sequence repeat markers. One hundred and thirty isolates of bamboo belonging to 13 geographically diverse populations were collected for DNA extraction and analysis. Heterozygosity, level of polymorphism, marker efficiency, Nei's gene diversity ( H ), and Shannon's information index ( I ) analysis, analysis of molecular variance (AMOVA), analysis for cluster, principal coordinates (PCoA), and admixture analyses were performed based on the markers banding pattern. The results indicated high genetic variation (84.48%) at species level. The H , I , observed and effective number of alleles at the species level were 0.2702, 0.4061, 1.8448, and 1.4744, respectively, suggesting a relatively high level of genetic diversity. However, genetic differentiation at the population level was relatively low. Using grouped populations, AMOVA revealed that most (61.05%) of the diversity was distributed within the populations with F ST = 0.38949, F SC = 0.10486, and F CT = 0.31797. Cluster analysis grouped the populations into markedly distinct clusters, suggesting confined propagation in distinct geographic regions. STRUCTURE analyses showed K = 2 for all populations and K = 11 excluding Gambella population. Using these markers, we found strong evidence that the genetic diversity of the lowland bamboo is associated with distinct geographic regions and that isolates of Gambella Region, with their unique genetic origin, are quite different from other bamboos found in the country.
