Evidence

Peer-reviewed field soil survey and spatial modeling

Geography

Gozamen District, Upper Blue Nile Basin, Ethiopia

System

Agricultural soils, grazing lands and forest

## WHAT THE EVIDENCE SAYS

Soil samples from six Ethiopian kebeles and satellite land-cover classification found pH from 4.11 to 6.58\. A mapped 43% very strongly acidic and 39% strongly acidic was method-dependent; cultivated and grazed areas tended to have more acidic soils than forests.

## WHY IT MATTERS / OUR READ

Where lime, soil amendments or restoration budgets depend on a map, test and disclose the interpolation method; use field samples to validate project-scale prescriptions.

## CAVEATS / UNCERTAINTY

Study area is limited to six kebeles; interpolation techniques shifted mapped class extents. Differences by land use do not alone prove vegetation causes pH change.
