Which outcome occurs when increased subsurface irrigation increases bioturbation?

💡 Explanation

Soil horizons mix via bioturbation as organisms move sediment. This increased mixing reduces soil profile horizon contrast, because the layers become less distinct together rather than retaining separate properties. Therefore it blurs the layers compared to distinct zones like A.
