Soil organic carbon and fertility interactions affected by a tillage chronosequence in a Brazilian Oxisol

Conversion of natural to cropland ecosystems results insignificant changes in soil physical, chemical, and biologicalproperties (Lal, 1976; Oades, 1984; Elliot, 1986; Potter et al.,1998). The plow tillage (PT) system has been used since the dawnof settled agriculture but its use intensified, with the onset of theindustrial era in 1850, especially in temperate regions (Lynch,1984). Principal objectives of PT in high latitudes are to acceleratesoil warming during spring, control weeds, and create edaphicconditions conducive to seedling establishment and crop growth.
