Abstract:
... High-yielding agriculture leads to dense straw cover (mulching). Soil-engaging tools for conservation tillage in these scenarios demand enhanced tool performance, e.g., improved soil penetration, reduced force requirement, better straw cutting and minimised soil disturbance. These interdependent and yet conflicting performances could not be easily realised with traditional tillage tools. Instead ...

Abstract:
... Conservation tillage is considered as a potential measure to mitigate climate change by sequestering soil organic matter (SOM), however its stabilization mechanisms remain elusive. In this study, we revealed the molecular composition of SOM in soil profile (~50 cm depth) from a 17-yr tillage experiment in North China. The soils were collected from 0–10, 10–20, 20–30 and 30–50 cm layers under ...

Abstract:
... Soil erosion has caused substantial nutrient losses in the hilly-gully area of the Loess Plateau in China. Consequently, traditional tillage provides little ecological benefit there, and conservation tillage is required instead. To identify a suitable conservation tillage mode for this region, we set up no-tillage (NT), straw mulching (SM), plastic mulching (PM), and ridge-furrow plastic mulching ...

Abstract:
... Since tillage can reduce the amount of organic C stored in soils, the use of conservation tillage practices, which exclude soil inversion, or include it less frequently, is often promoted. Soil microorganisms are closely linked to soil organic C (SOC), and they are assumed to respond quicker to management changes than SOC. Using two Swedish long-term tillage experiments, our aim was to determine ...
