✅ 二、硫镁肥的全球应用方案（Global Application Scenarios for Magnesium Sulfate Fertilizer）

Magnesium (Mg) and Sulfur (S) are essential secondary nutrients for plant growth, yet often overlooked in conventional fertilization. Magnesium sulfate (MgSO₄) offers an efficient and highly soluble solution for addressing these deficiencies across a wide range of crops and regions.
