Kieserite Powder is produced through advanced processing techniques to ensure high purity, fine particle size, and excellent solubility. It provides magnesium and sulphate efficiently to correct soil deficiencies and improve plant health.
Key Features:
High magnesium content (MgO 26–28%)
Sulphate (SO₃) 48–52%
Fine powder for quick dissolution
Compatible with fertigation systems
Moisture-resistant packaging
| Nutrient Component | Typical Content (%) |
|---|---|
| Magnesium (MgO) | 26–28 |
| Sulphate (SO₃) | 48–52 |
| Particle Size | 0.2–0.5 mm |
| Moisture Content | ≤ 1% |
| Solubility | >95% in water |
For optimal application, certain conditions should be met:
Soil pH: 5.5–7.5
Avoid waterlogged soils
Soil tests recommended to determine magnesium levels
Temperature: 15–35°C for best solubility
Humidity: Store and apply in low-humidity conditions to prevent caking
Sunlight: Keep shaded during storage
Mechanical spreaders or fertigation systems
Measuring devices for accurate dosage
Protective gear for handling fine powder (gloves, masks, goggles)
Correct operation ensures efficient nutrient delivery and crop health.
Conduct soil tests to determine magnesium deficiency.
Select appropriate application method (soil application or fertigation).
Prepare equipment: clean spreaders, mixers, or fertigation tanks.
Measure the required dosage: 100–200 kg per hectare depending on crop and soil.
Spread evenly using a mechanical spreader or manually.
Incorporate lightly into the top 2–5 cm of soil for uniform nutrient distribution.
Dissolve Kieserite Powder in water to prepare a magnesium-rich solution.
Apply via drip or sprinkler irrigation systems.
Monitor pH and EC to ensure optimal nutrient absorption.
Always wear gloves, goggles, and dust masks when handling the powder.
Avoid inhalation and direct skin contact.
Store remaining powder in a cool, dry, and ventilated area.
| Step | Action | Recommended Dosage/Condition |
|---|---|---|
| 1 | Soil Testing | Determine Mg deficiency levels |
| 2 | Equipment Setup | Clean and calibrate spreaders or fertigation system |
| 3 | Powder Application | 100–200 kg/ha for soil; 1–2% solution for fertigation |
| 4 | Incorporation | Lightly mix into topsoil (2–5 cm) |
| 5 | Monitoring | Check crop growth and soil magnesium levels |
Tips:
Apply before crop growth stages that require high magnesium (leaf development, flowering).
Avoid application before heavy rainfall.
Combine with NPK fertilizers for balanced nutrition.
Proper accessories enhance application efficiency:
| Accessory | Purpose | Notes |
|---|---|---|
| Mechanical Spreader | Uniform soil application | Calibrate before use |
| Fertigation Tank | Dissolving powder for irrigation | Ensure full dissolution |
| Measuring Scoops | Accurate dosing | Adjust based on soil test results |
| Protective Gear | Safety | Gloves, goggles, dust masks recommended |
| Storage Containers | Maintain powder quality | Moisture-proof and ventilated |
