“…A similar relationship between pH and available phosphorus has been reported by the Zaho et al, (2011) and Khokhar et al, (2012). Significant and negative relationship of pH with available sulphur has also been reported by Cheema and Arora (1984), Arora et al, (1989), Pandey et al, (1989) and Dar et al, (2011).…”

“…Since there was no significant difference in root colonization among sites, soil available P differences can be attributed to the soil pH, that was the lowest in both seasons in Lalis compared to Tarkin and Kheiroud. Furthermore, pH had a significant negative correlation with available P. Zhao et al (2011) stressed that available P increases with decreasing pH. It should be noted that in calcareous soil, P is retained by Ca ions and in acid soils it is retained by Fe and Al ions (Hisinger 2001).…”

© 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.

“…Compared to the two farming systems, favourable chemical values were measured in ecological field on the top of hill, except the inorganic N (Table 1), but at the bottom of hill the investigated parameters were higher in conventional field. The available nitrogen and carbon usually increased with increasing pH (Zhao et al, 2011). Generally, the most investigated parameters were higher in upper (0-30 cm) soil layer and also were higher in the bottom of hill, than in top of hill (except of nitrite-nitrate-N in ecological field).…”

SUMMARYThe growing human population has higher and higher food demand, which requires an increase in efficiency of agricultural production. Healthy and fertile soils are essential to satisfy this demand. The microbial community structure is an excellent indicator of the soil fertility and the diversity of bacteria and fungi. In our work we compared the effect of organic and conventional cultivation methods on the microbial community profiles of sandy soils in the Nyírség region, Hungary. These fields have topographical heterogeneity therefore the sampling sites were divided into top of hill and bottom of hill. Sampling was done in autumn 2013, from the 0-30 cm and the 30-60 cm soil depths. The phospholipid fatty acids (PLFA) were used for the monitoring of microbial community. PLFAs break down when the cell dies therefore these molecules show the community structure in a real time. In the 0-30 cm soil layer of organically managed field the PLFA structure was significantly different between top and bottom of hill, but the difference were low. In conventionally managed field, high differences were found between the PLFA groups measured in the top and bottom of hill. The PLFA values were higher in the top of hill in organic field, while in case of bottom of hills sites higher PLFA values were measured in conventional farming system. In the deeper soil layers the tendencies were found similar to the upper soil layer, but the measured values were lower.
