Tree growth and soil fertility in plantations of genetic materials of Eucalyptus spp.

Were analyzed the growth and relationship with soil fertility of genetic materials Eucalyptus spp. planted in a non-traditional eucalyptus forestry region Brazil. Five were selected, two seminal: urophylla E. pellita three clones: GFMO27, I224, H13, experimental plots completely randomized design. The diameter at breast height (DBH) total measured; basal area dendrometric variables calculated, for ages 24, 36, 48, 60, 72, 108 months, both statistically compared. was chemically characterized months age correlated variables. clones GFMO 27 superior to urophylla. levels N MO had significant correlation volume Al+3 showed positive DBH. Clone H13 higher values than other materials, all analyzed, reaching an individual 1.27 m³ months. (GFMO27, I244, urophylla) proved be variable their behavior different ages, lower growth. recommended planting are
