“…A similar result was found under Cunninghamia lanceolata/Michelia macclurei (conifer/broadleaf) mixed stands compared to the corresponding pure stands (Wang et al, 2007). In mine soils, Chiti et al (2007) found that the top mineral soil under Quercus robur/Alnus cordata mixed stand contained significantly more SOC than pure Quercus robur stand. The differences were attributed to the presence of either N-fixing or broadleaf trees in the mixed stands.…”

“…On the other hand, soils under mixed stands (conifer/broadleaf) of Pinus luchvensis/Schima wallichii (Qin et al, 2004) and Cunninghamia lanceolata/Michelia macclurei (Wang et al, 2007) had higher soil N than those under pure stands of constituent conifers. Chiti et al (2007) also found significantly higher soil N on mine soils under Quercus robur/Alnus cordata mixed stand than pure Quercus robur stand.…”

Interest in mixed-species plantations in the tropics has increased because they appear to provide a wider range of options, such as yield, biodiversity, nutrient cycling, and C sequestration than pure stands. Pure stands of Pinus patula Schlecht. and Charm., Juniperus procera Hochst., and Grevillea robusta A. Cunn., and mixed stands of P. patula/G. robusta, P. patula/J. procera, and P. patula/Podocarpus falcatus R. Br. at Wondo Genet in S Ethiopia were studied to examine (1) the impact of mixed-species plantations on soil chemical properties, and (2) the impact of mixed-species plantations on the nutritional status of constituent trees. Soil (0-50 cm depth) and foliage samples were collected from four random plots (100 m 2 ) in each of the pure and mixedspecies plantations. Soil samples were analyzed for organic C, N, and base cations. Foliage samples were analyzed for nutrients (N, P, K, Ca, and Mg). There were little significant differences in soil chemical properties and foliar nutrient concentrations of trees between the pure and mixed stands. Among pure stands, J. procera and G. robusta differed in soil exchangeable Ca ++ and K + at 0-5 cm soil depth and in foliar P and Ca concentration. After 18 and 24 y, mixed stands did not influence soil chemical properties and tree nutrition differently than pure stands. This may be due to additive interaction in mixed-species stands and the similarity of the constituent tree species in foliar nutrient concentration and their impact on soil chemical properties.

“…Accordingly, it is possible that Coniferous stands absorb more C compared to hardwood stands. This can be attributed to this fact that C changes in soil gradually and this change is depended on various factors such as vegetation cover, the amount of litter and plant debris, land use type and management (Chiti et al 2006). In a study by Kooch et al (2012) the carbon sequestration of soils under forest plantations with Acer, oak, and pine species were estimated.…”

“…Another reason could be the higher percentage of organic C in the soil of this stand, because the relationship between total carbon and total N is a positive correlation and it can be considered as a factor causing increased total N in mixed stand (Hagen-Thorn 2004). Because soil total N changes gradually and it depends on various factors such as vegetation cover, the amount of litter and plant debris, land use and management (Chiti et al 2006). Of other affecting factors, the acidity can be mentioned so that pH influences the amount of nutrient uptake by plants, microbial activity and changes in the of N and C absorption (Augusto et al 2002).…”

Rafeie Jahed R, Hosseini SM, Kooch Y. 2014. The effect of natural and planted forest stands on soil fertility in the Hyrcanian region, . In the present work, we studied the effect of natural and planted forest stands on soil fertility in the Hyrcanian region of northern Iran. Natural forest stands (including Acer velutinum Bioss., Zelkova carpinifolia (Pall), Parrotia persica (DC.) C.A.Mey, Quercus castaneifolia C.A. Mey., Carpinus betulus L, Mixed planted stand (including Acer velutinum, Ulmus carpinifolia G. Suckow Quercus castaneifolia C.A. Mey, Carpinus betulus L., Tilia begonifolia Scop. subsp. caucasia (Rupr.) Loria; maple (Acer velutinum Bioss) plantation, pine (Pinus taeda L.) plantation and also clear-cut region (control) were considered in this research. Soil samples were collected at two different depths, i.e., 0-15 and 15-30 cm, and characterized with respect to organic carbon (C), total nitrogen (N), available nutrient elements (P, K, Ca and Mg); pH and soil texture. The results showed that the highest amount of total N was found in mixed plantation. The highest amount of available P was detected in maple plantation and pine plantation had the highest available K and organic C than other treatments. The highest and the lowest available Ca and Mg were found in natural forest and control area, respectively. In addition, it was observed that nutrients accumulate in upper layers of the soil. Hardwood stands have been more successful than the conifers stands, so this should be considered in the sustainable management of forests.

Comparison among different schemes and plant densities in oak plantations (Quercus petraea [Matt.] Liebel.): a case study in Umbria, Central ItalyThe results of tree farming plantation, aged 20 years, characterized by three different planting designs are reported. The plantation designs differ in planting densities and by the presence/absence of N-fixing nurse trees and shrubs. The plantations intercropped with N-fixing trees and shrubs (B 33% and C 66%) showed superior increment in dbh and height. The plantation C characterized by valuable tree planted at definitive distances (8 m), lower tree density and higher percentage of N-fixing trees and shrubs (C) showed the best growth performance and no thinning need, but showed the worst stems quality. In plantation (C) the vigorous development of shrubs and brambles hindered the management, making the plantation not suitable for tourist and recreational activities, though more attractive for local wildlife. The plantation with high tree density characterized mainly by sessile oak (A) was more sensitive to insect attacks and needed to be early thinned, thus it is more suitable for tourist and recreational activities. The plantation B with high tree density and intercropped with N-fixing nurse shrubs showed higher growth, needed to be tinned and can be used for tourist and recreational activities too.
