No-tillage systems are able to reduce the negative effects of agricultural intensification on soil properties. However, knowledge of long-term impacts of no-tillage systems on soil properties is insufficient. It is essential to know which soil quality indicators are the most sensitive to management practices in each particular environment. Therefore, the objective of this work is to determine which soil quality prop-erties are more sensitive to the impact of two tillage systems in a vertic Argiaquoll soil from Buenos Aires, Argentina. This work started in 2006 and included crop rotation and tillage systems, including both tillage and no-tillage. physical and chemical properties were measured in three consecutive years (2013-2015) at two depths (0-10 cm and 10-20 cm). The tillage system modified soil physical and chemical properties, mainly in the surface layer. No-tillage showed significantly higher bulk density (2013-2015 p p p pporosity) was significantly greater under tillage. The tillage system did not affect hydraulic conductivity, total nitrogen and extractable phosphorus from the surface, nor physical and chemical properties from the second depth. No-tillage alleviates, but is not enough to mitigate, the loss of soil organic carbon and aggregate stability caused by continuous cropping in this vertic Argiaquall. Bulk density, organic carbon, aggregates stability and saturation are indicators for future studies performed in environments with similar soil and climate conditions.
