Abstract: The knowledge of the nutrient distribution in trees is important to establish sound nutrient management programs for citrus production. Six-year-old Hamlin orange trees [Citrus sinensis (L.) Osb.] on Swingle citrumelo [Poncirus trifoliata (L.) Raf. x Citrus paradisi Macfad.] rootstock, grown on a sandy Entisol in Florida were harvested to investigate the macro and micronutrient distributions of biomass components. The biomass of aboveground components of the tree represented the largest proportion of the total… Show more

“…According to Avelar et al (2008), physic nut is a plant that presents a high growth rate mainly in the first two years of cultivation, with N being essential for the assimilation of carbon and formation of new organs in the plant (TAIZ; ZEIGER, 2013). Compared to other plants, such as coffee tree (LAVIOLA; DIAS et al, 2008), guava (HAAG et al, 1993) and orange tree (MATTOS JÚNIOR et al, 2003), in the present study, physic nut presented 21.04 g kg -1 of N in the fruits, higher content than those found by these authors. According to Silva et al (2009), omission of macro and micronutrients for physic nut causes visual symptoms of nutritional deficiency, common to other species.…”

“…In the last year of fruit yield evaluation, nutrient removal from the soil by fruit harvests diminished the negative effect of K fertilization on the Valencia grove (data not shown). Potassium removal by fruits is equivalent to (1.5 to 2.0) kg·t -1 , which quantity is comparable with the N exported by fruit harvest and much greater than other nutrients [13,29].…”

“…Fruit yield and quality of citrus are greatly influenced by N and K supplies in tropical soils because these nutrients are subjected to losses in the environment [12] and are the ones most exported by citrus fruits [13]. Therefore, attention should be paid to establishing nutrient management strategies to improve growers' profitability.…”

“…Fruit yield and quality of citrus trees depends largely on nitrogen (N) and potassium (K) fertilization Alva et al, 2006), elements which represent the greatest quantity of nutrients exported through harvest (Bataglia et al, 1977;Mattos Jr. et al, 2003). Furthermore, under abiotic stress conditions as salinity or drought, N and K may contribute to reduce excess absorption of sodium (Na) and chloride (Cl) by citrus trees because of the competitive root uptake observed between NO 3 -/Cl -and K + /Na + (Gimeno et al, 2009).…”
