Aim Previously, we showed that sowing density influences root length density (RLD), specific root length (SRL) especially in the topsoil, and shallowness of fine roots of field grown spring barley ( Hordeum vulagre L.). Here, we ask which trait components may explain these observed changes. Method W...
