Off-field residue feeding could further reduce feed deficits during the dry-to-wet season transition.
Verbatim
e1“We found that modest SI measures (small fertilizer quantities, weeding, and crop rotation) led to moderate yield increases of between a factor of 1.2 and 1.6 and reduced soil carbon loss, but they sometimes caused increased growing-season water limitation effects”
e5“Off-field residue feeding during the dry-to-wet season transition could further reduce feed deficits and decrease rangeland grazing pressure during the early growing season”

Other claims from this paper (8)
- Intervention effect Modest sustainable intensification measures increased simulated crop yield by a factor of 1.2 to 1.6.
- Intervention effect Modest sustainable intensification measures reduced simulated soil carbon loss.
- Intervention effect Modest sustainable intensification measures sometimes increased growing-season water limitation.
- Observation Sustainable intensification effects on crops varied strongly between years.
- Intervention effect Dry-season crop residue grazing reduced feed deficits by approximately a factor of 2 compared with the rangeland-only scenario.
- Intervention effect Dry-season crop residue grazing could not fully compensate feed deficits during the dry-to-wet season transition.
- Recommendation Targeted deficit irrigation or water-retention measures may enhance sustainable intensification efforts.
- Recommendation Integrative modeling frameworks are needed to evaluate landscape-level interactions between ecosystem components.
