SALVADOR, Nilson; MION, Renildo Luiz  e  BENEZ, Sérgio Hugo. Consumption of fuel in different systems of periodical preparation performed before and after the subsoiling operation. Ciênc. agrotec. [online]. 2009, vol.33, n.3, pp.870-874. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542009000300029.

We studied the consumption of fuel in different systems of periodical preparation performed before and after the subsoiling operation on a soil classified as Dystroferric Red Nitosol. The systems of tillage periodic preparation were disc plowing; disc plowing followed by a light disc harrowing; heavy offset disc harrowing; heavy offset disc harrowing followed by a light disc harrowing, and chisel plowing. The specific consumption (g kWh-1) of fuel for the different systems of soil periodical preparation varied statistically with the subsoiling condition carried out before and after. The scarification resulted in a smaller volume of fuel requested by hectare (L ha-1) than the other systems of preparation. The soil preparation after the subsoiling resulted in a larger volume of fuel consumed by area (L ha-1).

Palavras-chave : Periodical tillage; subsoiling; fuel consumption.
