Dolomite Lime – How Garden Lime Can Cause Problems

Can dolomite or any other type of lime do as gypsum does and improve drainage? My hort trainer said gypsum can only work on dispersive clay (sodic), as the calcium in gypsum will have a stronger binding ability than the sodium and will bind particles together strongly, therefore opening up the soil for drainage.

The higher reactivity of orthorhombic C 3 A (ort-C 3 A) in sulfate-containing solutions, compared with cubic C 3 A (cb-C 3 A), was previously related to the differences in crystal structure or the sodium in the ort-C 3 A pore solution. We analyzed the hydration of cb-C 3 A (in water and NaOH solution) and Na-doped ort-C 3 A in the presence of gypsum and hemihydrate.

Dolomite - an overview | ScienceDirect Topics

Dolomite was the first fertilizer used to prevent hypomagnesemia (Cunningham, 1936).When applied at rates between 100 and 540 kg Mg/ha the Mg concentration of temperate forage is increased by 0.2–1.2 g/kg DM (Table 9.13).These increases in Mg concentration in the forage were associated with a rise in the level of exchangeable Mg in the soil (Jones, 1963b; Simpson, 1964).
