Abstract

While conventional tillage or full-width tillage (FT) helps with seed germination and improves crop growth by turning over soil and burying previous crop residues, this process can cause soil degradation due to wind and water erosion and soil organic carbon loss (Hobbs, Sayre, and Gupta, 2008). Conservation tillage was introduced in the 1930s as a method to reduce soil disturbance relative to FT. Typically, conservation tillage is defined as a tillage and planting system that leaves at least 30% of crop residue on soil surface at planting (CTIC, 2002).
