Hydrated Lime
Hydrated Lime: Essential Applications Across East Africa
Qualitas Company Limited is a leading supplier of Hydrated Lime in East Africa, distributing this versatile product across Kenya, Uganda, Rwanda, Sudan, and DRC Congo. Hydrated lime, also known as calcium hydroxide, is a crucial component in various industries due to its wide range of applications and benefits.
What is Hydrated Lime?
Hydrated lime (Calcium Hydroxide – Ca(OH)₂), also known as slaked lime, is commonly used in agriculture to improve soil conditions, regulate pH, and enhance plant growth. Here are its key benefits:
Synonyms
Calcium dihydroxide, Slaked lime, Hydrated lime, Lime, Milk of lime
Chemical Formula
Ca(OH)2
Benefits of Hydrated Lime in Agriculture
- Soil pH Regulation (Acidity Neutralization)
- Hydrated lime raises soil pH, making it less acidic, which is beneficial for crops that struggle in acidic soils.
- It reduces aluminum toxicity in acidic soils, which can be harmful to plant roots.
- Ideal for crops like barley, alfalfa, and legumes, which prefer near-neutral soil pH.
✔ Application Rate:
- 500–2000 kg per hectare, depending on soil acidity.
- Applied before planting and incorporated into the soil.
- Provides Essential Nutrients (Calcium & Magnesium)
- Calcium (Ca): Strengthens cell walls, improving plant structure and resistance to disease.
- Magnesium (Mg) (if present in dolomitic lime): A key component of chlorophyll, essential for photosynthesis.
✔ Application Rate:
- 100–500 kg/ha for nutrient supplementation in acidic soils.
- Improves Soil Structure & Water Infiltration
- Prevents soil compaction and crusting, leading to better root penetration.
- Enhances water infiltration and retention, reducing water runoff and erosion.
- Beneficial for heavy clay soils, helping break them down into a looser structure.
✔ Best Applied:
- Before planting or during fallow periods to allow proper soil incorporation.
- Disease and Pest Control
- Hydrated lime is used in Bordeaux mixture (with copper sulfate) to prevent fungal diseases in crops like grapes, tomatoes, and potatoes.
- Acts as a natural pest repellent, reducing soil-borne pathogens and insects.
✔ Usage:
- Bordeaux Mixture: Mix hydrated lime + copper sulfate + water for foliar disease protection.
- Powder Application: Lightly dust over affected plants to deter pests.
- Improves Nutrient Availability
- Reducing soil acidity makes nutrients like phosphorus, nitrogen, and potassium more available to plants.
- Helps legumes like soybeans and peanuts fix nitrogen more efficiently.
✔ Application Timing:
- 3-6 months before planting for best results in pH correction.
- Avoid mixing directly with fertilizers like ammonium sulfate to prevent nutrient loss.
- Reduces Toxicity of Heavy Metals
- Binds with toxic metals (e.g., aluminum, lead, cadmium) in the soil, reducing their uptake by plants.
- Useful in industrial farmlands or soils with a history of pollution.
✔ Best Applied:
- In contaminated soils at 2-5 tons per hectare based on soil test recommendations.
Precautions When Using Hydrated Lime
❌ Avoid over-application, as excessive lime can lead to alkalinity issues.
❌ Do not mix with urea-based fertilizers (ammonia loss may occur).
❌ Use protective gear when handling, as hydrated lime is caustic and can irritate skin/eyes.
