Abstract

A move in the use of the land has been one of two main harms for the increase in Stove Efficiency
Gases (GEE’s). Therefore, the search for a more sustainable and less polluting production system has been
increasingly frequent in the agricultural sector. From this, or present objective study to assess the carbon
stock (C.Est.) and the C/N ratio of only, comparing Conventional Soybean Planting (SPC), Direct Planting
of Soybean/Milho (SMPD) and Native Vegetation (VN), In closed conditions, in depths of 0-10 cm and 10
20 cm, in random blocks with subdivided plots. As results, it was observed that the Est.C has a significant
difference in relation to area, highlighting the SMPD (75.71 Mg.ha-1), in relation to the other areas, but
there are no significant differences in depth, being Apresented 73.88 Mg.ha -1 (0-10 cm) and 68.77 Mg.ha-1
(10-20 cm). In the C/N ratio, there were also significant differences in the interaction between 0-10 cm and
10-20 cm, respectively, the following data for SMPD (82.88 and 55.43 Mg.ha-1), SPC ( 37.91 and 57.68
Mg.ha-1) and VN (46.07 and 43.46 Mg.ha-1). Verify that the SMPD system was or that it presented better
characteristics, as well as greater carbon permanence, not only the soil.
Keywords: direct planting, conventional planting, native vegetation.
