英文摘要	Carbonates participate in soil aggregation and, therefore, influence the essential agrophysical properties of soil. Irrigation, using both fresh water and treated wastewaters (FW and TWW), can interfere with the soil carbonate system and affect (micro)aggregation. We undertook a micromorphological study on a series of characteristic Mediterranean soils irrigated with FW and TWW, emphasising the effects of carbonate microaggregation. Methods of microaggregate and gross chemical analyses and scanning electron microscopy were applied. The results showed that irrigation, using both FW and TWW, had diverse effects on the micromorphological patterns of the soils. In the soils irrigated with FW, and especially in clayey Vertisol, significant formation of pedogenic calcite occurred. FW appears to be a primary source of HCO(3)(-)and Ca(2+)for the soils. The formation of calcite-clay microaggregates, enlarged and agronomically optimal in size (20-200 mu m) and stability, would benefit the soil structure and enhance its soil filtration capacity, features favourable for heavy-textured Vertisol, Terra rossa, and Loessial arid brown soils. In the soils irrigated with TWW, partial dissolution of primary crystalline carbonates and subsequent precipitation of metastable amorphous carbonates in the form of calcite micronodules was observed. This would promote water-retention capacity of light Sandy soils. Additionally, an unusual toroid-shaped microform of CaCO(3)was found in TWW-irrigated Vertisol and Loessial arid brown soil, presumably under the effect of dissolved organic matter.
