The current study was developed with disturbed samples of an Oxisol, in which ‘Siciliano’ lemon trees seedlings (C. limon) were grafted on sour orange tree (C. aurantium) and rangpur lime tree (C. limonia). The experiment consisted of three basis saturation levels (50, 70 and 90 percent) and three boron doses (0.5; 1.5 and 4.5 mg dm-3) in the planting with 3x3x2 factorial experimental design with four replications. Mineral composition of the "Siciliano" lemon leaves as well as root system development in sour orange tree were higher than the rangpur lime tree. There was no effect in the interaction basis saturarion level and the boron doses for any of the evaluated parameters.

Understanding the growth pattern of fibrous, orange tree [Citrus sinensis (L.) Osbeck] roots enables proper fertilizer placement to improve nutrient uptake efficiency and to reduce nutrient leaching below the root zone. The objective of this study was to develop relationships defining citrus fibrous root length density (FRLD) as a function of soil depth, distance from the tree trunk, and tree size. Root systems of 18 trees with tree canopy volumes (TCV) ranging from 2.4 to 34.3 m3 on two different rootstocks and growing in well-drained sandy soils were sampled in a systematic pattern extending 2 m away from the trunk and 0.9 m deep. Trees grown on Swingle citrumelo [Citrus paradisi Macf. × Poncirus trjfoliata (L.) Raf.] rootstock had significantly greater FRLD in the top 0.15 m than trees on Carrizo citrange (C. sinensis × P. trifoliata). Conversely, Carrizo citrange had greater FRLD from 0.15 to 0.75 m below the soil surface. FRLD was significantly greater for ‘Hamlin’ orange trees grown on Swingle citrumelo rootstock at distances less than 0.75 m from the tree trunk compared with those on Carrizo citrange. Fibrous roots of young citrus trees developed a dense root mat above soil depths of 0.3 m that expanded both radially and with depth with time as trees grow and TCV increased. Functional relationships developed in this study accounted for changes in FRLD with increase in tree size.
