From: Effects of tillage on the root length and depth distribution of stubble cover crops
The correlations between average aboveground dry mass yield and average root length or root dry mass at 0–60 cm at Ruzyně (Ruz) and Lukavec (Luk). Tillage treatments included ploughing (PLO) and reduced shallow tillage (RET). * denotes significance at p < 0.05 (n = 7).
