WEBOct 13, 2021 · Calcium and Mg influence soil aggregation and soil structure, thus affecting soil health. The Ca 2+ ion is smaller than Mg 2+ hence it is more efficient in binding soil particles, and has more flocculating power (the ability to facilitate the formation of small masses) than Mg. Conversely, Mg could lower soil structural stability.
