Other claims from this paper (10)
- Intervention effect Acidic subsoil reduced shoot N uptake of wheat compared with limed subsoil.
- Intervention effect Acidic subsoil reduced root length in the subsoil and the deep-root ratio compared with limed subsoil.
- Intervention effect Acidic subsoil reduced NO3-N depletion compared with limed subsoil.
- Observation Spelt line KU-1025 had the greatest root dry weight and total root length of the genotypes under both limed and acidic subsoil treatments.
- Observation KU-1025 maintained a high deep-root ratio under acidic subsoil conditions.
- Observation KU-1025 showed lower soil NO3-N concentrations and less N leaching than the two wheat cultivars.
- Association Across genotypes and treatments, shoot N uptake was positively correlated with root dry weight and total root length.
- Association Across genotypes and treatments, N leaching was negatively correlated with root dry weight and total root length.
- Mechanism The authors suggest that maintaining a large root system, rather than deep rooting alone, is important for improving N capture and reducing N loss under acidic subsoil.
- Recommendation The authors suggest KU-1025 may provide useful genetic variation for breeding wheat adapted to acidic subsoil environments.
