Nitrogen (N) and phosphorus (P) are the nutrients that most commonly limit tree growth. Interactions between fertilization and soil type are well known, and in soils with moderate or low N availability, N-fertilization is frequently recommended to improve tree nutrition. The aim of this paper was to analyze how different doses of P and N applied in three different types of soils affect dry mass and nutrient accumulation and partitioning in Eucalyptus grandis young plants, and if fertilization with P may increase N uptake. Fertilization was applied as 1, 2 and 4g of urea (46% of N) or 6, 12 and 24g of triple superphosphate (20% of P) per plant. Dry mass and nutrient partitioning were analyzed 44, 72 and 84 days after transplanting (DAT). Interactions between soil type and fertilization were observed. Root:total mass ratio decreased with P-fertilization in all soils. Fertilization with P promoted growth and improved N and S …
