We investigated macropore characteristics caused by agricultural exploitation of desert soils. Soil physicochemical properties significantly improved after cultivation. Soil macroporosity increased with cultivation time. Macroporosity was 8.7–18.9 times greater in irrigated croplands than native desert.
