“…Therefore, to obtain an index that provides and integrates more information on the quality of a given soil, multiparametric indices have been developed for agro-ecosystems and for non-agricultural soils (Bastida et al, 2008). In this case, the soil quality indicators should be a combination of chemical, physical and biological properties (Herrick et al, 2002;Aparicio and Costa, 2007) and the indicator values can be combined into a quantifiable soil quality index (SQI). A valid SQI would thus help integrate and interpret data from various soil measurements, and indicate whether the land use was having a desired effect on productivity, environmental protection and health (Granatstein and Bezdicek, 1992).…”

“…Bulk density was replaced by maximum δ b in Eq. (1), the resulting value was considered the textural porosity (ρ t ) (Aparicio and Costa, 2007). The ρ t values used to calculate the structural porosity (ρ s ) as follows:…”

“…Soil organic carbon has a very important role to play in other edaphic properties. Hati et al (2006) emphasized its influence on the retention and movement of water in the soil, whereas Aparicio and Costa (2007) reported a significant and positive correlation of SOC with hydraulic conductivity (r = 0.6; 0.001 < p < 0.05) and a negative one with the δ b of the soil (r = −0.6; 0.001 < p < 0.05). There is a strong relationship between soil microbiological activity, organic matter and the structural stability of the soil (García-Orenes et al, 2010).…”

Abstract. South American countries with the highest surface of land under no-tillage (NT) management are Brazil, Argentina and Chile. In Argentina, 78.5 % of the agricultural land is cropped under NT management. Several experiments have confirmed the improvements in soil aggregation and infiltration achieved by NT management in dry-land farming areas associated with increases of bulk density (δ b ) under NT management. An increase in bulk density implies a reduction of the macro and mesoporosity that is in contradiction with the increased infiltration that occurs at macro and mesopores. We hypothesize that the increase of bulk density in NT management mainly affects the mesopores. We evaluated the evolution of the soil physical parameters in three management systems in four farmers' fields. We found that the reduction in total porosity under NT management is mainly a product of a reduction in the percentage of mesopores in the soil. In this work, the results indicate a modification of some soil physical parameters (porosity, near-saturated hydraulic conductivity, soil structure) due to uninterrupted agricultural production, but the management system did not affect the yields of crop.

“…Soil quality indicators have been defined as soil processes and properties that are sensitive to changes in soil functions (Doran et al, 1996;Aparicio and Costa, 2007). Considering the natural conditions of Daxing District, nine indicators (Table 1) were selected in this study.…”

The objectives of this study were (i) to assess soil fertility quality changes in time and space using grey relational analysis (GRA) and geographic information systems (GIS) in the urban-rural transition zone of Beijing and (ii) to explore the variation features of soil fertility under different land use types and soil management practices. The distribution map of soil fertility quality showed that soil fertility quality was best in the north, south, southeast and middle part of the district in 1980. The first-grade quality (I) was mainly in the southeast and the third-grade quality (III) was mainly in the north, south, northwest, east and middle part of the district.
