Plant Availability of Magnesium in Typical Tea Plantation Soils.

ABSTRACT: Background and Aims: Magnesium (Mg) fertilizer has been proved to play an important role in improving the yield and quality of tea. However, plant availability of Mg, including its use, efficiency, and quality improvement effects, were highly affected by plant species, soil characteristics (nutritional status, etc.), and Mg status (chemical-available, etc.). Methods: Tea plants were pot-cultivated in 12 typical tea plantation soils amended with and without Mg fertilizer. Exchangeable Mg (Ex-Mg) concentration in soils was quantitatively extracted using four extraction solutions (Mehlich-3, BaCl₂, CaCl₂, and NH₄OAC). Plant availability of Mg was evaluated by Mg uptake and its use efficiency, as well as its association with quality components in
