山东省土壤代换性钙含量为２１．８～７１０ｍｇ／１００ｇ土，平均为３１３．８ｍｇ／１００ｇ土，＜２００ｍｇ／１００ｇ土的占２１．５４％。棕壤、非黄河冲积性潮土为低钙土类，褐土、潮土、盐土、水稻土为中钙土类，砂姜黑土为高钙上类，平均每１００ｇ上分别含１８４．８、２４６．６、３５７．８、１７１．２、３２２．０、３２１．４和４１１．６ｍｇ。代换性钙呈明显区域性分布，鲁东低山丘陵区为潜在性缺钙区，鲁中南中低山丘陵区为部分潜在性缺钙区，鲁西北泛滥平原区为富钙区。土壤有机质、ｐＨ值、粘粒、碳酸钙及质地均能影响代换性钙含量。
Soil substitutional soil calcium content in Shandong Province ranged from 21.8 to 710 mg / 100 g, with an average of 313.8 mg / 100 g soil and 21.54% of soil with <200 mg / 100 g soil. Brown soil and alluvial alluvial soil of non-Yellow River are calcareous soil, cinnamon soil, alluvial soil, saline soil and paddy soil are medium calcium soil, and lime concretion black soil is high calcium soil, with an average of 184.8 per 100g, 246.6, 357.8, 171.2, 322.0, 321.4 and 411.6 mg. Substitutional calcium showed a significant regional distribution, Ludong hilly area potential calcium deficiency area, Lu Zhongnan hilly area as part of the potential calcium deficiency area, northwestern plain floodplain area for the calcium-rich area. Soil organic matter, pH, clay, calcium carbonate and texture can affect the substitutional calcium content.
