Evidence

Peer-reviewed

Geography

Global saline croplands

System

Saline agricultural soils

## WHAT THE EVIDENCE SAYS

A spatial nitrogen budget and pairwise synthesis found salinity associated with 13% higher nitrogen inputs, 7% lower nitrogen harvest and 61% higher reactive-nitrogen losses. Across ten management categories, the authors estimate potential to cut annual reactive-nitrogen losses by 59% while increasing crop production.

## WHY IT MATTERS / OUR READ

Soil salinity is not only a yield constraint; it changes nutrient efficiency and pollution risk. That couples salinity adaptation to fertilizer and water management.

## CAVEATS / UNCERTAINTY

The mitigation estimates are global synthesis/model potential, not guaranteed field outcomes. Costs, salinity type, water availability, adoption, soil chemistry and local agronomy will constrain realized benefits.
