Discing
A soil tillage practice using disc implements to break up clods, incorporate crop residues, and control weeds by cutting the soil surface.
Также говорят: harrowing, disc tillage, disking
Discing is employed for both primary and secondary tillage, facilitating the incorporation of organic matter and fertilizers into the topsoil. This process effectively aerates the soil and improves water infiltration while maintaining soil structure by avoiding deep inversion.
The operation is typically carried out post-harvest or in early spring to manage moisture levels. Achieving optimal results depends on adjusting the disc angle and travel speed, which determines the depth of penetration and the degree of residue fragmentation.
Common mistakes include operating on overly wet soil, which leads to compaction or smearing, and improper speed selection, which can result in uneven field leveling and premature wear of the disc blades.
