“…In addition, there was a significant correlation between diameter and phosphorus concentration (r 2 = 0.941 and 0.884 at M1 and M3 with 0.01 and 0.05 significant levels, respectively). Xu (2002) also found a relationship between P concentration and aboveground growth, i.e., trees allocated more biomass to aboveground growth under marginal and adequate P supply. However, this study found that stem density and/or the concentration of phosphorus in soil, can affect an increase in diameter.…”

“…phytic acid (Schachtman et al 1998). As the phosphorus supply in soils in south China is commonly limiting for tree growth (Tan et al 2015, Xu et al 2002, it is recommended that luxury phosphorus additions be applied to nursery stock prior to outplanting in nutrient-poor or weed-prone sites. Apart from the amount of fertilizer, the nutrient addition ratio and rate should also be considered to improve nutrient efficiency in the future (Isaac et al 2011, Kelly & Ericsson 2003.…”

“…The nitrogen loading requirement of B. alnoides has been studied (Chen et al 2010), however the phosphorus requirement of this species being considered for further reforestation is unknown. Generally, the soils of southern China limit the growth of plantation tree species (Xu et al 2002). Therefore, we investigated the growth and nutrition responses of four B. alnoides clones to phosphorus.…”

“…O alto requerimento de nutrientes pelo eucalipto, associado a essas características do solo, torna a fertilização uma técnica fundamental para sustentabilidade das florestas (Barros & Novais, 1996;Pampolina et al, 2002;Xu et al, 2002). A absorção de nutrientes pode alcançar valores (kg ha -1 ) de até cerca de 1.200 para Ca, 1.000 para N e 700 para K, dependendo da espécie, da taxa de crescimento e da qualidade do sítio (Attiwill & Adams, 1996).…”

“…Em florestas plantadas, o P é usualmente o elemento limitante ao crescimento, especialmente na fase inicial, provavelmente por sua baixa mobilidade no solo e alta adsorção aos oxi-hidróxidos de Fe e de Al (Barros & Novais, 1990Bä et al, 1999;Xu et al, 2002). As respostas do eucalipto à aplicação de fertilizantes à base de P e de K têm sido bem mais acentuadas (Prezotti et al, 1988;Barros & Novais, 1990;Faria et al, 2002) do que as obtidas pelo emprego do N e do Ca.…”
