Which mechanism limits agricultural productivity in alluvial plains with high sedimentation rates?

💡 Explanation

When sedimentation rates are high, the mechanism of over-burial occurs because frequent deposition covers young plants, depriving them of light and air exchange. Therefore, burial directly arrests growth pattern, rather than erosion, waterlogging, or salinization which result from distinct processes, such as soil depletion or excessive irrigation.
