Soil acidity is a common problem in many agricultural regions around the world. When the soil pH is too low (acidic), it can limit the availability of essential nutrients and reduce crop yields. That’s where Magnesium Oxide (MgO) comes in — a powerful and efficient soil amendment used to raise soil pH and provide essential magnesium.
🌱 What Is Magnesium Oxide?
Magnesium Oxide is a white, powdery or granular compound produced by calcining natural magnesite or brucite. It is rich in magnesium (Mg), a secondary nutrient that plays a critical role in plant photosynthesis and overall crop health.
🧪 How MgO Improves Soil pH
When applied to acidic soils, MgO reacts with moisture and carbon dioxide in the soil to form magnesium hydroxide (Mg(OH)₂) and then magnesium carbonate (MgCO₃). These compounds help neutralize hydrogen ions, effectively raising the soil pH toward a more balanced, productive level.
🌾 Benefits of Using MgO for Soil Amendment
- Increases pH efficiently – MgO has a higher neutralizing value than dolomite or lime.
- Provides essential magnesium – Magnesium is a key component of chlorophyll, improving photosynthesis and plant vigor.
- Improves nutrient availability – A balanced pH enhances the uptake of nitrogen, phosphorus, and potassium.
- Supports sustainable farming – Reducing soil acidity helps improve long-term soil fertility.
📌 How to Use MgO for Soil Treatment
- Form: Granular MgO is ideal for controlled-release and easier application, while powder form reacts faster.
- Application rate: Depends on soil pH and crop type — usually guided by soil testing.
- Timing: Best applied before planting or during soil preparation stages.
