The work’s objective was to evaluate, in field conditions, four forest species behavior submitted to different organic manurings and minerals with the addition of a conditioning of soil (Hidroplan). The adopted statistical outlining was in blocks, structured in portions subdivided with 30 treatments that consisted of combinations of factors (6 fertilizers x 5 times) with 5 repetitions, being used one plant by portion. Height (h) and diameter of the plants (d) were assessed. The data were submitted to the variance analysis and the average test (Newman-Keuls 5%). The seedlings were produced in a nursery, in inside polyethylene tubas and they ware planted in field 90 days after the rustic. The manurings tested in the experiment were: bovine manure; chicken manure; mineral manuring NPK (testifies); bovine manure + Hidroplan; chicken manure + Hidroplan and mineral manuring NPK + Hidroplan. The studied organic fertilizers contributed to a better acting in every species, except for the Eucalyptus urophylla, which had a better acting in NPK and NPK + Hidroplan.
