Levantamento do componente arbóreo do sistema Integração Lavoura- Pecuária- Floresta do IFMG campus Bambuí

The search for sustainable agriculture has driven the use of integrated farming systems, in which agricultural, forestry and livestock (ICLF) activities are incorporated into the same production unit, aiming at harmonizing the components of the agroecosystem. In the context of the forestry component, eucalyptus is mostly used. This present study aimed to survey the arboreal component of the integrated systems of crop-livestock-forest (ICLF) of the Federal Institute of Education, Science and Technology of Minas Gerais (IFMG) – Bambuí campus. The information gathered was the number of existing plants in the area, spacing in which the plants are submitted, plant material implanted (clone), plant age, chest diameter and height of all trees. With the collected information, it was observed that the plant material implanted in the area are two Eucalyptus clones - I144 and Super clone - at the age of 10 years. A total of 170 trees were measured in this survey, and it was noted that these trees are arranged in single and double rows, with varying spacing. The rows of the double rows are spaced 13 m apart regardless of the spacing between and within the rows in which they were planted. The double rows have spacing of (3.4x3.1 m) + 13 m with an average DAP of 26.11 cm and average height of 23.42 m; another spacing found was (3.4x3.3 m) + 13 m with DAP and mean heights of 27.37 cm and 25.36 m, respectively, and in the spacing of (3x2.8 m) + 13 m with mean DAP of 29.06 cm and average height of 26.27 m. With regard to the simple lines, it was not possible to measure the spacing of trees and rows. The DAP of three rows was measured, showing an average DAP of 32.73 cm, 31.59 cm and 36.04 cm.
