Other claims from this paper (14)
- Intervention effect Fertilizer did not materially change grain yield under natural rainfall.
- Intervention effect Added water raised continuous wheat yield by one-half.
- Intervention effect Added water raised fallow wheat yield by three-quarters.
- Intervention effect Fertilizer with added water increased wheat-fallow rotation yield by one-third.
- Intervention effect Fertilization did not affect grain P content.
- Intervention effect Additional water raised grain P content relative to natural rainfall.
- Association Grain P content was higher in continuous wheat than fallow wheat.
- Association Grain N content depended on shifts in N and P balance under fertilizer or added water.
- Observation Unused available N accumulated as nitrates in lower soil depths under natural rainfall, particularly with wheat-fallow.
- Intervention effect Nitrate did not accumulate where supplemental water, alone or with fertilizer, was applied.
- Intervention effect Water and fertilizer increased surface-soil organic N and reduced organic C loss.
- Intervention effect Water and fertilizer reduced surface-soil organic C loss.
- Intervention effect Fertilizer sharply increased soil NaHCO 3 soluble P, especially with supplemental water.
- Intervention effect Water alone increased demand on soil P and reduced soluble P content.
