“…However, there was no clear trend of distribution with depth, Haidouti et al (2001) found similar patterns. MacKenzie (1980) reported that higher values were usually found in soils with high Fe and organic matter content in semiarid environments.…”

“…Drainage conditions have promoted decalcification, illuviation, and differentiation of the soil layers (Darwish and Zurayk 1997). Available micronutrients Fe, Cu, Zn, and B were generally less than the sufficiency levels to sustain crop production in all pedons (Mengel and Kirkby 1979;Martens and Lindsay 1990), confirming previous studies in Greek soils (Haidouti et al 2001). Surface horizons were rich in Mn and Cu, and certain horizons of P1, P5, and P6 contained sufficient amounts.…”

“…Contents of exchangeable K + and Na + were rather low in all soil profiles representing a small part of CEC. Although Greek soils contain sufficient amounts of exchangeable potassium, it seems that the studied red soils constitute an exception (Haidouti et al 2001). No clear trends with depth were observed for exchangeable K + , whereas Na + , a more mobile element, was generally increased.…”

“…Red (allochthonous) soils of Thrace, Greece, were developed on Quaternary calcareous deposits, belong to the great group of Rhodoxeralfs, and are located on several geomorphic surfaces on moderately to gently sloping landscapes (Yassoglou, Kosmas, and Moustakas 1997;Haidouti et al 2001). However, the pedogenetic environment, classification, and red pigmentation of red soils in the Mediterranean basin are still a matter of controversy because of the high soil diversity.…”

The studied Alfisols were developed on Quaternary calcareous deposits and belong to the great group of Rhodoxeralfs. They occur usually in the mesoMediterranean bioclimatic zone and are affected by water deficit during the summer period. They are located mainly on backslope geomorphic surfaces, old terraces, and alluvial fans, and their erodibility is medium to low. Trends of decreased iron content in the deeper soil layers due to severe drainage conditions may be responsible for relatively low values of free iron oxides (Fe d ). The rather limited variation of Fe d may reflect the specific pedogenetic conditions in which red soils were formed. Indices of pedogenesis [Fe o /Fe d (Fe o : amorphous Fe), Fe dFe o , and iron illuviation index of Fe d ] indicated that the studied pedons are at different stages of development. Redness indices (RI) of Bt horizons in pedons were found in the following decreasing order: P1 5 P5 . P4 5 P6 . P2 . P3. There were no clear trends of free manganese oxide (Mn d ) distribution with depth. The lack of correlation between Mn d and clay or Fe d suggested that Mn d oxides do not take part in the co-illuviation of clay and Fe d oxides. Acidity, low content of organic carbon, exchangeable potassium (K + ), available phosphorus (P), and water deficit are the main impediments to crop production on these soils. Geomorphological and physicochemical properties suggest that rotation schemes, minimum tillage, liming practices, soil leveling, use of proper irrigation systems, and micronutrient application are among the suggested practices to sustain crop production and mitigate erosion risk.
