Simulation of soil organic carbon changes in Vertisols under conservation tillage using the RothC model

Conservation tillage induced changes in organic carbon, total nitrogen and available phosphorus in a semi-arid alkaline subtropical soil

A multi-year experiment was conducted to compare the effects of conservation tillage (no-till and ridge-till) with conventional plow tillage on organic C, N, and resin-extractable P in an alkaline semi-arid subtropical soil (Hidalgo sandy clay loam, a fine-loamy, mixed, hyperthermic Typic Calciustoll) at Weslaco, TX (26890N 978570W). Tillage comparisons were established on irrigated plots in 19...

Tillage Effects on Soil Organic Carbon Fractions in Mediterranean

Soil aggregation and organic carbon protection in a no-tillage chronosequence under Mediterranean conditions

Modelling tillage and nitrogen fertilization effects on soil organic carbon

1 Agricultural management plays an important role in global warming mitigation due to 2 its effects on soil organic carbon (SOC) dynamics. In Mediterranean agroecosystems, 3 the interactive effects of tillage and N fertilization on SOC storage have scarcely been 4 studied. Hence, we here present a modelling study in which the effects of both tillage 5 and N fertilization on SOC dynamics are inv...

Soil Organic Carbon Pools as Early Indicators for Soil Organic Matter Stock Changes under Different Tillage Practices in Inland Pacific Northwest

Soil organic matter (SOM) is essential for sustaining soil health and crop productivity. However, changes in SOM stocks in response to agronomic practices are slow and show years later when it is too late for adjustments in management. Identifying early indicators of SOM dynamics will allow early management decisions and quick remedial action. The objectives of this study were to evaluate long-...
