Furrow slice turnover
Furrow slice turnover is a tillage technique where the soil layer is inverted to bury crop residues and improve soil structure.
Также говорят: furrow inversion, plowing turnover, soil inversion
The main purpose of furrow slice turnover is to manage weed populations and incorporate surface biomass into the deeper soil layers, where it decomposes more efficiently. This process enhances the biological activity of the soil and promotes the distribution of organic matter throughout the active root zone.
This method is typically used during primary tillage in the autumn to prepare fields for the next cropping season. Proper adjustment of the plow body is crucial to ensure that the furrow slice is completely inverted without leaving large air gaps or fragmented soil aggregates.
Common mistakes include incomplete turnover, often caused by incorrect travel speed or improperly set coulters, which allows weeds to resprout. Excessive tillage intensity can destroy soil structure, leading to crusting and compaction, commonly known as plow pan, which restricts root penetration and water drainage.
