Description
Manganese Sulphate Monohydrate
Dosage
- 🌿 Foliar Spray: Dosage: 5-10 grams per liter of water (0.5%–1% solution) Application Frequency: Every 7–14 days Best Time: Early morning or late afternoon (avoid strong sunlight) Note: Ensure thorough leaf coverage, but avoid runoff.
- 💧 Fertigation (Drip Irrigation / Hydroponics): Dosage: 5–10 kg per acre per application (or 5–10 g per liter of water in hydroponics) Frequency: Weekly or as needed during flowering/fruiting stages Dilution: Dissolve completely in water before application
- 🌱 Soil Drench (less common for this formula): Dosage: 20–40 grams per liter of water Use Case: When foliar or fertigation isn't feasible
Benefits

Role of Manganese in Plants
Helps in photosynthesis (water splitting & oxygen release).Supports chlorophyll formation and leaf greenness.Activates enzymes for nitrogen, carbohydrate & lipid metabolism.Aids auxin (growth hormone) synthesis.Strengthens cell walls → better disease resistance.

Symptoms of Manganese Deficiency
Interveinal chlorosis → yellowing between veins, especially on young leaves.Brown/grey spots (manganese speckling) on leaves.Reduced leaf size and poor chlorophyll development.Weak stems and stunted growth.Lower yield and poor quality of produce.

Improved Crop Growth and Yield
By ensuring adequate Manganese supply, it promotes healthy vegetative growth, better root development, and ultimately leads to increased crop yields. This is particularly significant in crops highly susceptible to Manganese deficiency like maize, rice, wheat, pulses, oilseeds, fruits, and vegetables.

Versatile application
Suitable for all crops – cereals, pulses, fruits, vegetables, oilseeds, cash crops.Can be applied by soil application, foliar spray, or fertigation.Effective for correcting deficiency quickly (foliar) and maintaining long-term supply (soil).Improves growth, yield, and stress tolerance across diverse soils and climates.
Things to Consider
Nutrient composition
Check the specific nutrients included in the ammonium sulphate and verify it aligns with your plants' needs. Some popular micronutrients in these blends include Nitrogen and Sulphur.
Application rates
Always follow the instructions on the product label for proper dilution and application frequency to avoid overfertilization.
Plant compatibility
Certain plants might be sensitive to specific nutrients. Research the appropriate blends for your plant types.
Soil testing
While helpful, fertilizers might not address underlying soil deficiencies. Consider soil testing to determine specific nutrient needs for targeted solutions.
