Abstract

This study aimed to evaluate the influence of soil preparation and mineral fertilization on according to the morphological growth and leaf morphofunctional attributes of native species used in the revegetation of the well base area of oil extraction. The experimental design was in randomized blocks in a split-plot scheme with 4 replications. The plots were the two soil types, and the subplots were the 5 planting fertilization treatments with NPK 04-14-08 with 0, 40, 80, 160 and 320 g pit^-1. Four native species were planted and individually evaluated. The species responded in a variable way depending on the applied fertilization. The type of soil statistically influenced the number of leaves of Inga laurina, showing a greater number when cultivated in clayey soil. The other species did not differ in terms of soil type. For planting fertilization, it is recommended to apply 219.27 to 227.25 g pit^-1 for Schinus terebinthifolius Raddi and 189.83 g pit^-1 for Mouriri guianensis. The application of planting fertilizer for S. terebinthifolius Raddi and M. guianensis is recommended. The species Inga laurina, Garcinia brasiliensis and Chrysobalanus icaco developed better without planting fertilization. Leaf attributes demonstrated an adaptive response of plants regarding to environmental stress conditions to which they were submitted.
