山东省土壤有效铁含量,棕壤、水稻土分别为20.9和43.9μgg~(-1),属富铁土壤;褐土、潮土、盐土分别为9.3、11.3和9.60μgg~(-1),部分土壤潜在性缺铁;风沙土、砂姜黑土分别为7.2和7.5μgg~(-1),属低铁土壤.剖面中表层含量高,底土层最低,水稻土、棕壤表现最明显.境内自东而西、自南而北逐渐降低,山地丘陵高,平原低.土壤母质来源、熟化程度、酸碱度、碳酸钙含量和水分状况强烈影响铁的有效性,粘粒和全铁量影响不大.
Soil available iron content in Shandong Province was 20.9 and 43.9 μg / (-1) for brown soil and paddy soil respectively, belonging to iron-rich soil. Cinnamon soil, alluvial soil and saline soil were 9.3, 11.3 and 9.60 μg / And some of the soils were potentially iron deficiency.The aeolian sandy soil and saprolium black soil were 7.2 and 7.5μgg -1, respectively, belonging to the low-iron soil.The content of surface layer was the highest in the section, the lowest in the subsoil, and the most obvious in paddy soil and brown soil. From east to west, it gradually decreased from the south to the north, with high hills and low plains. The source of soil parent material, the degree of maturation, pH, calcium carbonate content and water status strongly influenced the availability of iron, with little effect of clay and total iron content .
