 For instance, a recent meta-study concluded that miscanthus had nine times less subsurface loss of nitrate compared to maize or maize grown in rotation with soya bean.The fibrous, extensive miscanthus rooting system and the lack of tillage disturbance improves infiltration, hydraulic conductivity and water storage compared to annual row crops, and results in the porous and low bulk density soil typical under perennial grasses, with water holding capabilities expected to increase by 100–150 mm.Nsanganwimana et al.
