“…Higher foliar Ca levels and Ca/Al ratio and lower Al levels led to greater HP productivity. Higher Ca availability following fertilization of acidic forest soils was shown to lead to increased HP growth (Bilodeau-Gauthier et al 2011;Elferjani et al 2013), whereas low Ca/Al ratio are associated with an increased probability for detrimental effects on tree growth (Cronan and Grigal 1995). Similarly, the alkalinizing effect of lime mud used in our study was beneficial for HP nutrition and growth.…”

“…Successful fertilization programs must rely on indicators for optimal nutrition (species-or clone-specific), repeated assessments of the nutritional status of trees (Mead 2005) and optimization of fertilizer applications (i.e. type of fertilizer, application rate, timing and frequency of application) for maximum tree growth (Elferjani et al 2013;Albaugh et al 2018).…”

Growth and foliar nutrition of a hybrid poplar clone following the application of a mixture of papermill biosolids and lime mud

Fertilization of hybrid poplar (HP) plantations with papermill by-products is a promising solution to improve soil fertility and nutrient availability, increase plantation productivity, and provide added value to these materials that would otherwise be incinerated or sent to the landfill. We assessed the growth and foliar nutrition of a HP clone (Populus x. canadensis × P. maximowiczii) at six plantation sites aged three to five years in southern Quebec, Canada. Sites received a fertilization treatment consisting of a mixture of papermill biosolids (120 to 140 t ha-1, depending on site) and lime mud (10 to 15 t ha-1) before being planted, or no fertilization (control). Tree growth was significantly improved by fertilization, with fertilized trees showing a mean annual height increment of 1.3 m (all-site mean; SD = 0.2), compared with 0.5 m (SD = 0.4) for unfertilized trees. Foliar Ca and Mg increased following fertilization and levels met optimal thresholds at all sites, whereas N, P, and K concentrations also increased but nutritional deficiencies remained for these elements at several sites. Our results confirm the benefits of fertilizing hybrid poplars with papermill by-products, but indicate that adjustments in application rates or type of by-products could be made in order to fully satisfy nutritional requirements and thus optimize tree growth.

“…While there are many successful experiences in growing forest plantations in tropical and sub-tropical regions, increasingly much attention has been paid on short-rotation, fastgrowing poplar plantations in the temperate (Heilman 1999;Liberloo et al 2006) and boreal (Elferjani et al 2013) zones on Earth. Poplar plantations accounts for 13.5 % of China's total forest plantations in area (Wilske et al 2009).…”

An analysis of potential investment returns and their determinants of poplar plantations in state-owned forest enterprises of China

et al. 2014

China's state-owned forest enterprises have been important national timber production bases and their timber resources have been severely degraded during the past decades. About one-third of the state-owned forestland has been classified as commercial forestland, but no economic mechanisms have been laid out on governing timber plantations under market economy. This paper demonstrates the potential investment returns and analyzes factors that directly influence the returns of fast-growing poplar plantations in a state owned-forest enterprise, China Jilin Forest Industry Group (CJFIG), in northeastern China. We examined practically possible ranges of mean annual increment (MAI), general inflation rate, rate of forest fund, and interest rate in the study area. We then computed net present values (NPV), equivalent annual income (EAI) and internal rate of return (IRR) by using the minimum, medium, and maximum values of the each determinant above.
