Abstract

GOEDERT, Wenceslau J.; SCHERMACK, Marcio Julio  and  FREITAS, Frederico Carneiro de. Soil compaction status in areas under notill system. Pesq. agropec. bras. [online]. 2002, vol.37, n.2, pp.223-227. ISSN 0100-204X.  http://dx.doi.org/10.1590/S0100-204X2002000200015.

Evaluation of soil compaction status was performed in an experimental plot and farming area, in two private farms located in the Federal District, Brazil, that have been used under notill system for a long period. Two procedures were used: density and mechanical resistance to penetration in soil layers. The results show that no compaction was detected after seven years of cropping, which can be explained by the good original soil physical properties and to the suitable farm management.

Keywords : soil density; soil porosity; mechanical resistance to penetration; savannah.
