Srikar Mag Magnesium Sulphate Fertilizer

Water-Soluble Magnesium Sulphate Fertilizer for Crop Nutrition

Srikar Mag is a fully water-soluble Magnesium Sulphate fertilizer developed to supply important secondary nutrients to crops. It contains approximately Magnesium 9.5% and Sulphur 12% and is useful for preventing and correcting magnesium deficiency in agricultural and horticultural crops.

Magnesium plays an important role in chlorophyll formation and photosynthesis, while sulphur contributes to several plant metabolic processes. Srikar Mag helps maintain crop greenness, supports nutrient utilisation and can be applied through foliar spray, fertigation or soil application according to crop and soil requirements.

Benefits of Srikar Mag Magnesium Sulphate

• Helps correct magnesium deficiency in crops.
• Supports chlorophyll formation and greener foliage.
• Helps improve photosynthetic activity.
• Supplies both magnesium and sulphur.
• Supports efficient nutrient utilisation by plants.
• Helps maintain healthy vegetative and reproductive growth.
• Can support crop quality and productivity when magnesium or sulphur is limiting.
• Suitable for a wide range of agricultural and horticultural crops.

Why Magnesium Is Important for Plants

Magnesium is an essential secondary nutrient and forms the central part of the chlorophyll molecule. Adequate magnesium availability is therefore important for normal photosynthesis and maintenance of healthy green leaves.

Magnesium also participates in several enzyme reactions and supports the movement and utilisation of other nutrients within plants. Deficiency can reduce crop vigour and photosynthetic efficiency.

Why Sulphur Is Important for Crops

Sulphur is required for the formation of certain amino acids, proteins and enzymes. Adequate sulphur nutrition supports normal crop growth and development and can be particularly important in high-yielding crops.

Srikar Mag supplies both magnesium and sulphur in a water-soluble form, making the nutrients readily available when used correctly.

Magnesium Deficiency Symptoms

Magnesium deficiency commonly appears first on older leaves because magnesium is mobile within the plant. Typical symptoms may include:

• Interveinal yellowing of older leaves.
• Leaf veins remaining green while areas between veins become yellow.
• Reduced leaf greenness.
• Poor photosynthetic activity.
• Premature ageing or drying of affected leaves in severe deficiency.
• Reduced crop vigour where deficiency persists.

Similar symptoms may also be caused by other nutritional or soil problems, so soil or tissue analysis can help confirm the deficiency where required.

Recommended Crops

Srikar Biotech recommends Srikar Mag for all crops. It can be used in cereals, pulses, oilseeds, vegetables, fruit crops, plantation crops, flowers and other agricultural crops according to nutrient requirements.

Dosage and Method of Application

The exact dose and number of applications should be adjusted according to crop, growth stage, soil condition, nutrient status and label recommendations.

Foliar Spray Schedule

For foliar application, dissolve approximately 4–5 g of Srikar Mag per litre of water. Srikar recommends the first spray approximately 25–30 days after sowing or transplanting.

The spray may be repeated twice at approximately 15-day intervals during the crop season where required. Crop condition and deficiency severity should be considered before repeat applications.

Use in Cotton

Srikar specifically notes that magnesium nutrition can be useful in cotton where red-leaf symptoms are associated with magnesium deficiency. The company recommends up to three foliar sprays at the stated dose as part of nutritional management.

Red leaves in cotton can have several causes, so magnesium application should be based on crop symptoms, soil conditions and local agronomic guidance.

Fertigation Application

Srikar Mag is fully water soluble and can be applied through suitable fertigation systems. Srikar recommends approximately 2–3.5 kg per acre per day, with the exact quantity depending on crop, soil type and crop growth stage.

Ensure complete dissolution before introducing the product into the irrigation system and follow good fertigation practices to prevent precipitation or clogging.

Soil Application

For field crops and oilseed crops, Srikar recommends approximately 20–25 kg per acre through soil application.

Soil application rates should ideally be based on soil-test results, crop nutrient demand and existing magnesium levels.

Suitable Crop Growth Stages

Srikar Mag can be applied during both vegetative and reproductive growth stages. Magnesium demand can increase as the crop canopy expands and photosynthetic activity rises.

• Early vegetative growth.
• Rapid canopy development.
• Pre-flowering and flowering stages.
• Fruit, pod or grain development where magnesium deficiency is observed.

How to Use Srikar Mag as Foliar Spray

1. Fill the spray tank partially with clean water.
2. Measure the required quantity of Srikar Mag.
3. Dissolve the product completely in a separate small quantity of water.
4. Add the dissolved fertilizer to the spray tank.
5. Add the remaining water and mix thoroughly.
6. Apply uniformly over crop foliage.
7. Prefer spraying during cooler morning or evening conditions.

How to Use Through Fertigation

1. Calculate the required dose according to crop and field area.
2. Dissolve Srikar Mag completely in clean water.
3. Filter the solution where required before injecting into the irrigation system.
4. Apply uniformly through the fertigation system.
5. Flush the irrigation system with clean water after application where appropriate.

Compatibility

Srikar describes Srikar Mag as compatible with many soluble fertilizers and commonly used agrochemicals. However, compatibility depends on the complete tank mixture, water quality and product formulation.

• Check all product labels before mixing.
• Conduct a small jar test before preparing an unfamiliar mixture.
• Avoid incompatible nutrient combinations that may form precipitates.
• Do not prepare highly concentrated mixtures without checking compatibility.

Application Tips

• Apply based on visible deficiency symptoms or soil/tissue analysis where available.
• Use clean water for foliar applications.
• Ensure complete dissolution before spraying or fertigation.
• Use properly calibrated spraying equipment.
• Avoid foliar application during very hot midday conditions.
• Do not exceed the recommended concentration.
• Adjust soil application rates according to soil-test results where possible.
