Highlights ► I checked the hypothesis on dominant role of the greenhouse gas CO 2 upon the recent global warming. ► Proxies from glaciers and paleosols document periods with higher temperature than our recent values while the CO 2 concentration was below recent level. ► The hypothesis on...
Highlights ► Long-term conservation tillage systems improved the crop response to N fertilization. ► Intensive tillage reduced soil water content and accumulated nitrates in the soil. ► No-tillage improved the environmental and economical sustainability of the system.
Highlights ► Bioindicators showed that the intensively managed soils are biologically degraded. ► Bioindicators were effective in discriminating between benchmark and intensively managed sites. ► Of the univariate indicators, the OM/PA index had the strongest discriminatory power. ► PCA...
Highlights ► Continuous no-tillage and organic C inputs increased soil organic C and N and altered soil C distribution. ► No-tillage plus organic C inputs enhanced soil microbial biomass and activities. ► No-tillage dominantly impacted soil C and N over organic inputs. ► Sustainable...
Highlights ► Long-term tillage effects on soil chemical and physical properties are investigated. ► With appropriate production intensity, average yields were not affected by tillage. ► Conservation tillage led to significant P and K stratification. ► Penetration resistance and bulk...
Highlights ► Sicilian vineyards are prone to erosion risks. ► Pole method measure erosion rates in a longer period. ► Planting the appropriate cover crops decreases soil erosion.
Highlights ► We found 35–179 g m −2 y −1 of soil loss and 5% average runoff coefficient in tilled steep vineyards. ► The enrichment ratio of eroded sediments for N, P or OM was 1.7 on average. ► Less erosion and runoff and a significant increase in OM was realized after three years of...
Highlights ► The overall performance of RothC was very good. ► There were not identifiable trends among crop sequences. ► RothC tended to underestimate SOC stocks. ► Misestimations of C input could have been the cause of the deviations. ► RothC can be used to simulate SOC, provided...
Highlights ► Small differences in soil stress in the topsoil and subsoil between tracks and dual wheels, but much higher for single wheels. ► Small differences in soil penetration resistance and bulk density in the topsoil between tracks and dual wheels, but much higher for single wheels. ►...
Highlights ► Relationship between sugarcane root density and soil physical parameters. ► Soil density ( Ds ) and penetration resistance ( Pr ) decreased with depth. ► The soil surface layer between rows showed the highest Pr value (1.93 MPa). ► The boundary line approach enables...
