Double row spacing of 0.90 × 1.50 m for sugarcane. (A) Deep Strip Tillage (DST) with a tilled and no traffic lane (DST-BED), and a traffic lane (DST-TRA). (B) Conventional Tillage (CT) with a no traffic lane (CT-NTV) and a traffic lane (CT-TRA). Hachured areas indicate soil tilled (1,20 m for DTS-BED corresponding to deep strip tillage equipment width). Root sampling points are relative to the planting row. The collected roots comply with relevant institutional, national, and international guidelines and legislation.
