SUMMARY
The objective of this work was to evaluate the influence of soil impervious layer about surviving plus diameter and height growth rates of seedlings of Eucalyptus grandis (Hill) ex Maiden. The treatments of soil tillage are subsoiling (T1) and not subsoiling (T2). After 12, 24, 36 and 43 months from planting the results indicated a positive diference in all variables for seedlings planted in area with subsoiling, even so there wasn’t significative statistical diference between treatments planted seedling.
Key words:
Impervious layer; subsoiling; growth rate; Eucalyptus
