๐ฑ Uses of Manganese Sulphate in Agriculture
Manganese Sulphate is an essential agricultural micronutrient fertilizer used to correct manganese deficiencies in soil and plants. It supplies manganese (Mnยฒโบ) in a soluble, plant-available form. Manganese plays several crucial physiological roles in crop development, yield, and quality.
โ 1. Corrects Manganese Deficiency in Soil & Plants
Primary Use:
The most common use of manganese sulphate is to treat manganese deficiency in soils and crops. Deficiency symptoms include:
-
Interveinal chlorosis (yellowing between leaf veins)
-
Reduced root growth
-
Stunted plant growth
-
Poor fruit set or grain formation
Common in: Alkaline, sandy, organic-rich, or over-limed soils, where Mn becomes insoluble and unavailable to plants.
MnSOโ is highly effective because it is highly water-soluble and rapidly absorbed by plant roots and leaves.
๐งฌ 2. Key Role in Plant Metabolic Functions
Manganese is a cofactor for several enzymes. It plays a crucial role in:
-
Photosynthesis: It is involved in photolysis of water (splitting water) during photosynthesis.
-
Chlorophyll synthesis: Essential for leaf greenness.
-
Nitrogen metabolism: Assists in nitrogen assimilation and protein synthesis.
-
Carbohydrate metabolism: Helps in sugar transport and storage.
Without manganese, these metabolic functions are impaired, leading to significant yield loss.
๐ 3. Enhances Disease Resistance and Stress Tolerance
Manganese strengthens plant cell walls by promoting lignin synthesis. This makes plants:
-
More resistant to fungal and bacterial pathogens
-
Better able to handle abiotic stress like drought and salinity
Example: In wheat, adequate Mn helps prevent take-all root rot. In citrus, it reduces gummosis susceptibility.
๐พ 4. Improves Crop Yield and Quality
Manganese sulphate contributes to:
-
Improved grain filling in cereals
-
Better fruit size and sweetness in fruits
-
Uniform vegetative growth
-
Early maturity and flowering
Manganese deficiency during early stages often leads to poor root growth and weak plant structure, directly impacting final yield.

DOSAGE:
๐ง 1. Hydroponics / Constant-Feed Systems
-
Stock Solution:
Dissolve 0.9โ1 g of Manganese Sulphate per litre of water to create a concentrated solution. -
Working Dosage:
Use 2.5 mL of stock solution per litre of nutrient solution to achieve 1.5 ppm Mn in hydroponic systems. -
Application Frequency:
Continuous feeding or weekly replenishment depending on system type.
๐ฟ 2. Foliar Spray Application
Severity of Deficiency | Dosage (per 100 Litres water) | Equivalent MnSOโ (g/L) |
---|---|---|
Preventive / Mild | 1 lb = 454 g | ~4.5 g/L |
Moderate | 2 lb = 908 g | ~9 g/L |
Severe | 3 lb = 1.36 kg | ~13.5 g/L |
-
Timing: Spray during early vegetative growth or immediately upon noticing deficiency symptoms.
-
Spray Volume: 200โ300 L/acre (depending on crop canopy).
๐พ 3. Soil Application Dosage (Broadcast or Band)
Application Type | Dosage per Acre | Dosage per Hectare |
---|---|---|
Broadcast | 20โ60 lb (9โ27 kg) | 22โ66 kg MnSOโ/ha |
Band / Side-dress | 10โ30 lb (4.5โ13.6 kg) | 11โ33 kg MnSOโ/ha |
-
Incorporate into soil before or at planting for best availability.
-
For alkaline soils, use the higher end of the range or the foliar route.
๐ 4. Crop-Wise Application Guide
Crop | Application Type | Rate & Timing |
---|---|---|
Cereals (Wheat, Barley, Maize) | Foliar Spray | 5โ9 kg MnSOโ/ha in 200โ300 L water at tillering (GS21) or early growth |
Soil Application | 25โ30 kg/ha MnSOโ pre-planting | |
Soybean / Pulses | Foliar Spray | 5 kg MnSOโ/ha at early vegetative stage |
Vegetables (Leafy, Tomato, Brinjal) | Foliar Spray | 4.5โ9 g/L or 1โ2 lb/100 gal; repeat after 10โ15 days if needed |
Soil Application | 20โ25 kg/ha before transplanting | |
Cotton / Sugarcane | Foliar Spray | 5โ6 kg MnSOโ/ha in 250 L water after 45โ60 days of planting |
Banana / Papaya | Foliar Spray | 5 kg/ha every 45โ60 days during growth |
Citrus Trees | Foliar Spray | 3โ5 lb MnSOโ per acre in spring/summer |
Soil Application | 22โ32 kg MnSOโ/acre once annually | |
Grapes / Pomegranate | Foliar Spray | 5โ7 kg/ha in 200 L water before flowering and fruit setting |
๐งช 5. Ideal Manganese Levels for Crops
-
Leaf Tissue Sufficiency: 20โ200 ppm
-
Deficiency Level: < 20 ppm
-
Soil Mn Level:
-
Deficient if < 3โ10 ppm (DTPA extractable)
-
Optimum: 10โ50 ppm
-
โ ๏ธ 6. Important Usage Notes
-
Always check soil pH. High pH (>6.5) soils tie up manganese; foliar application is preferred in such cases.
-
Avoid overuse โ manganese toxicity can occur, especially in acidic soils.
-
Use clean water for foliar applications to prevent clogging and leaf burn.
-
Compatible with most fertilizers and pesticides, but do a jar test before mixing.
๐ 7. Conversion Reference
Unit | Equivalent |
---|---|
1 ppm | 1 mg/L (in liquid) or 1 mg/kg (in solid) |
1 lb | 0.45 kg |

๐ง๐พ Consultation Note
Before applying manganese sulphate:
-
๐ Always perform a soil and leaf tissue analysis to determine actual Mn deficiency levels.
-
๐งช Choose application method based on deficiency severity, soil pH, and crop type.
-
๐ Over-application may lead to nutrient imbalance or toxicity, especially in low-pH soils.
-
โ For tailored recommendations and safe use, consult an agronomist or local agricultural officer.
