Other claims from this paper (15)
- Observation Soil pH and exchangeable cation concentrations were highest during 2012, the season after a flood event.
- Observation Soil electrical conductivity (EC1 : 5) was lowest during 2012.
- Observation In subsequent dry seasons, soil pH and cation concentrations decreased.
- Observation In subsequent dry seasons, soil electrical conductivity (EC1 : 5) increased.
- Intervention effect Maize sowing gave higher exchangeable Ca and Mg in the upper horizons (0–0.3 m) during 2012.
- Intervention effect Maize sowing gave higher exchangeable Na and exchangeable sodium percentage at 0.45–1.20 m, but these differences disappeared in later years.
- Intervention effect Maize sowing gave higher surface soil organic carbon (SOC) three years after sowing.
- Intervention effect Maize sowing gave no increase in SOC storage.
- Intervention effect Soil under maize was less resilient to structural degradation.
- Intervention effect Black root rot incidence was lower in maize-sown plots, but only during 2012.
- Association Stepwise regression suggested that high exchangeable Ca and Mg in the surface 0.15 m reduced black root rot incidence in 2012.
- Intervention effect Maize rotation introduced into cotton monocultures reduced greenhouse gas emissions.
- Intervention effect Maize rotation had little impact in a minimum-tilled cotton–wheat rotation.
- Recommendation Maize is a suitable rotation crop for irrigated cotton in a two-crop sequence.
- Recommendation Maize offers little advantage in a cotton–wheat–maize sequence.
