Over the past twenty years soil redistribution by tillage has gained worldwide recognition as a process of soil erosion and a major cause of soil degradation on cultivated land on rolling landscapes. Soil redistribution due to conventional tillage practices represents per se a process of intense transformation of the soil and geomorphic landscapes in agricultural lands. The accumulated long-term effects result in a drastic modification of the soil profiles and spatial patterns of soil variability. Moreover soil redistribution by tillage results in a severe modification of the landscape topography, and as a consequence on the surface and subsurface hydrology (e.g., variability of infiltration, overland flow paths...), which gives rise to a drastic modification of geomorphic processes (e.g., slope stability, water erosion...). A better understanding of the implications of soil redistribution by tillage may require reinterpretation of current agricultural landscapes. This reveals the need for studies identifying current landscape features produced by past repeated tillage practices, as well as for documenting the bio-physical implications (hydrology, water erosion, soil variability, soil quality, productivity...) consequent upon such landscape transformations.
The special session on “Tillage Erosion or How Farmers Built New Landforms” will discuss topics on past and present landscape transformation by tillage, soil degradation, experimental and laboratory studies, processes and factors, field measurement and quantification, modelling and mapping erosion risk assessment, prediction and soil conservation policies of agricultural land. Papers on these topics are welcome.
