“…Several authors have reported that soil K content is influenced by elevation, total nitrogen, and organic matter (Basumatary & Bordoloi 1992, Gairola et al 2012. In the present study, no significant differences among sites and no significant correlations between K and soil chemical properties were detected, according to previous findings by Paudel & Sah (2003).…”

© iForest -Biogeosciences and Forestry IntroductionArbuscular mycorrhizal fungi (AMF) play a critical role in the early establishment of land plants (Redecker et al. 2000). They can improve the host plants growth (Wu et al. 2011), improve plant nutrient and water uptake, enhance plant tolerance to environmental stresses, including metal tolerance, and are abundant in the plant rhizosphere interface (Smith & Read 2008, Xu et al. 2008, Barea et al. 2011. AMF are important micro-organisms which contribute to plant diversity and ecosystem functions (Van der Heijden et al. 1998). About 80% of higher plants have associations with arbuscular mycorrhizae (Smith & Read 2008). These associations lead to better phosphorous (P) absorption (Rooney et al. 2011) and the fungi can supply up to 80% of P and 25% of nitrogen (N) to the host plants (Marschner & Dell 1994). In turn, the fungi are highly dependent on their host plants for carbon nutrition (Smith & Read 1997). P is an important element which is actively supplied to host plants by AMF. The amount of P influx into colonized roots can be three to five times higher than non-mycorrhizal roots (Smith et al. 2003).Some soil characteristics have significant influences on the development of mycorrhizal fungi in roots, such as potassium (K), nitrogen (Treseder 2004), pH (Isobe et al. 2007, and compaction (Waltert et al. 2002), as well as climatic conditions and host plant effects (Kivlin et al. 2011). Increasing soil acidity or alkalinity was also a detrimental factor to AMF sporulation in field soils (Isobe et al. 2007). AMF also affect soil enzymes (Huang et al. 2009, Wu et al. 2011 by increasing activities such as dehydrogenase, phosphatase and urease (Huang et al. 2009).Wild service tree (Sorbus torminalis L. Crantz) is widely distributed across Europe, north-western African forests, and southwestern Asia (Nicolescu et al. 2009). It is also a rare, protected tree species found in the northern forests of Iran at elevations between 170 to 2700 m a.s.l., where it can reach up to 34 m in height (Pourmajidian 2000). Different species of the genus Sorbus are found in association with both arbuscular mycorrhizal and ecto-mycorrhizal fungi (Raspe et al. 2000).In this study, we hypothesized that AMF colonization of specific plants can vary significantly between sites with different soil characteristics. A comprehensive study was conducted to determine how AMF colonization of a wild service tree (Sorbus torminalis) was influenced by soil nutrients and enzyme activities at three different sites. A better understanding of AMF relationships with the wild service tree and its role in nutrient absorption and soil enzymes will enable better management of the tree stands in terms of nutrient uptake and more vigorous tree growth. Materials and methods Study sites and samplingThe study was conducted in a natural mixed forest of northern Iran consisting of Fagus orientalis Lipsky, Carpinus betulus L., and Acer cappadoeicum Gled along with a minor population of Sorbus torminalis.

“…In addition, the results indicated that the organic matter, the most important nitrogen source (Gairola et al 2012), was higher in Tarkin than in the other sites. Moreover, we observed a significant correlation between total nitrogen and the organic matter, according to Gairola et al (2012).…”

“…The values are also similar to the studies done in other parts of Uttarakhand consisting banj oak and pine forests viz. Gairola et al (2012) and Joshi and Negi (2015). Principal component analysis was done to find out the key information from the multivariate dataset by plotting all the data along with first two principal components ( Figure 5).…”

The present study is aimed to study regeneration status, population structure, soil characteristics and carbon stock of seven regenerating banj oak (Quercus leucotrichophora) forests in the central Himalaya. The phytosociological study was done by using ten 10 m Â 10 m quadrat at each site. Biomass and carbon stock of trees were calculated by using regression equations. Soil samples were collected from three depths (0-10, 10-20 and 20-30 cm) by using soil corer. The tree density of two most dominant species of the study sites i.e. banj oak and pine (Pinus roxburghii) varied from 260-1200 trees ha À1 and 90-300 trees ha À1 , respectively. Whereas, basal area of banj oak and pine varied between 5.5-21.0 m 2 ha À1 and 6.4-26.0 m 2 ha À1 , respectively. Density-diameter curve indicated the increasing population of banj oak while declining pine in all the sites. Carbon density of the banj oak was found between 46.96-167.36 Mg ha À1 and in pine it was 17.18-72.95 Mg ha À1 . Soil nutrient (especially carbon and nitrogen) improved with increase in density and basal area of forests. Additionally, substantial amount of carbon stored by these trees makes them viable for the region. Thus, identification and conservation of such forests are recommended.

“…As per Champion and Seth (1968) it is one of the dominant tree species in the tropical moist as well as dry deciduous forests in India. Some previous studies about physico-chemical characterization of soil were also done by researchers in various forests of Kumaun and Garhwal Himalaya (Joshi and Negi, 2015;Khera et al, 2001;Singh et al, 2009;Semwal et al, 2009;Sharma et al, 2010;Jina et al, 2011;Gairola et al, 2012;Kumar et al, 2013;Joshi, et al, 2013;Mehta et al, 2014;Upreti et al, 2016;Tewari et al, 2016;Bharti, et al, 2016). Present study is focused on the comparison of soil physico-chemical profiling of three different forest types (Oak, Pine and Sal) of Betalghat region of Kumaun Himalaya, Uttarakhand.…”

Article Info Received : 20.12.2017 Accepted : 09.06.2018 Soil is one of the basic natural resources on which all forms of terrestrial life co-exist. The soils of three forest types i.e., banj-oak (Quercus leucotrichophora A. Camus) chir-pine (Pinus roxburghii Sargent) and sal (Shorea robusta Gaertn. f.) of Betalghat block, Nainital District, (Kumaun Himalaya). Soils were drawn from three depths viz. 0-10 cm, 11-20 cm, 21-30 cm. The present study were studied resulted to soil physico-chemical properties i.e. maximum soil texture (sand 34.30 %, silt 57.21 % and clay 33.23 %), soil moisture (12.6 %), bulk density (1.43 g.cm -3 ), porosity (52.06%), water holding capacity (69.27%) and the maximum values of chemical analysis i.e. pH (6.80), total carbon (3.82 %), organic matter (6.57 %), total nitrogen (0.36 %), available potassium (267 mg/kg) and available phosphorous (62 mg/kg). Banj-oak forest shows rich physical properties followed by sal and chir-pine forest while chir-pine forest shows rich chemical properties in compared to sal and banj-oak forest.
