“…The stronger response of seedling growth to application rate than to the change of N:P2O5 ratio suggest that N and P elements are equally important to the growth of tree seedlings (Huat et al 2002, Klooster et al 2012, Wang et al 2013, despite some possible influences of formulation on seedling nutrient uptake (Walker & Huntt 2000, Oliet et al 2004). The equal significance of N and P to Chinese yew and Zhejiang Phoebe seedlings is also revealed from strong correlations of N and P concentrations and uptakes with growth and utilization efficiency of nutrient uptake (EuU).…”

“…Container stock seedlings are superior to bare-root seedlings in terms of survival and growth (Yuan et al 2012, Wang et al 2013. The use of polymer-coated controlled-release fertilizer (CRF) at time of planting can promote seedling survival (Irino et al 2005, Oskarsson et al 2006, Fu et al 2017) and early growth (Huat et al 2002, Hawkins et al 2005, Irino et al 2005, Jacobs et al 2005, Oskarsson et al 2006, Ruthrof et al 2010, Burney & Jacobs 2011, Sloan & Jacobs 2013, Fu et al 2017. It is especially useful to employ CRF to seedlings in the face of harsh site conditions, such as intensive vegetation competition, poor soil nutrient availability, and heavy canopy shade (Devine et al 2007, Burney & Jacobs 2011, Sloan & Jacobs 2012, Earnshaw et al 2016).…”

Decline of species population, low natural regeneration, and heavy competition on field sites require the planting of large seedling stocks to restore Taxus chinensis and Phoebe chekiangensis in tropical China. In this study, we examined the effects of different formulations and application rates of controlled-release fertilizers (CRF) of nitrogen (N) and phosphorus (P) on nursery seedling growth and nutritional attributes. The objective was to determine optimum formulation (N:P2O5 ratio) and application rate to increase nutrient reserves of the seedlings before transplanting to the field. Four formulations (17-9-13 to 19-6-14 N-P2O5-K2O ratios) and four application rates (1.5 kg m -3 to 4.5 kg m -3 ) were used in a double-factors factorial design with 3 replications. The results showed that CRF formulation can affect nutritional attributes, while application rate modified seedling growth and nutritional attributes. The optimum seedling response occurred with the 17-6-16 formulation at the rate of 3.5kg m -3 . These findings will guide nursery practice in the production of high-quality seedlings for optimum survival and growth in the field. (2019).

“…However, seedlings under control treatment showed decreased rates of AM colonization (Table 2). In general, AM fungal infection was suppressed under fertile conditions 12) . Using Moreover, the nutrient levels in the leaves and roots of Olea and Dodonaea seedlings were increased by application of biochar (Table 3).…”

In northern Ethiopia, revegetation is necessary for preventing land degradation. However, planting seedlings show high mortality under arid climate. Biochar has the capacity to enhance seedling survival and symbiosis with arbuscular mycorrhizal fungi. We planted Olea europaea subsp. cuspidata and Dodonaea angustifolia into soil treated with biochar made from Acacia etbaica. We could not confirm the effects of biochar on the growth of these species; however, biochar was increased colonization of arbuscular mycorrhizal fungi. We concluded that application of biochar enhanced symbiosis with arbuscular mycorrhizal fungi under arid climate and was efficient for the revegetation in northern Ethiopia.

“…AM fungi improved growth of the Brazilian pine Araucaria angustifolia (Araucariaceae) (Zandavalli et al 2004). Conversely, A. excelsa inoculated with AM fungi (without fertilizer) grew more slowly than did the uninoculated plants (Huat et al 2002). For example, Muthukumar et al (2001) reported that inoculation of Azadirachta indica (Meliaceae) with AM fungi improved seedling growth.…”
