Product Overview

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 ComponentTypical Content (%)
Magnesium (MgO)26–28
Sulphate (SO₃)48–52
Particle Size0.2–0.5 mm
Moisture Content≤ 1%
Solubility>95% in water

Installation Conditions

For optimal application, certain conditions should be met:

Soil Requirements

  • Soil pH: 5.5–7.5

  • Avoid waterlogged soils

  • Soil tests recommended to determine magnesium levels

Environmental Conditions

  • Temperature: 15–35°C for best solubility

  • Humidity: Store and apply in low-humidity conditions to prevent caking

  • Sunlight: Keep shaded during storage

Equipment Requirements

  • Mechanical spreaders or fertigation systems

  • Measuring devices for accurate dosage

  • Protective gear for handling fine powder (gloves, masks, goggles)


Operation Procedures

Correct operation ensures efficient nutrient delivery and crop health.

Step 1: Preparation

  1. Conduct soil tests to determine magnesium deficiency.

  2. Select appropriate application method (soil application or fertigation).

  3. Prepare equipment: clean spreaders, mixers, or fertigation tanks.

Step 2: Soil Application

  1. Measure the required dosage: 100–200 kg per hectare depending on crop and soil.

  2. Spread evenly using a mechanical spreader or manually.

  3. Incorporate lightly into the top 2–5 cm of soil for uniform nutrient distribution.

Step 3: Fertigation Application

  1. Dissolve Kieserite Powder in water to prepare a magnesium-rich solution.

  2. Apply via drip or sprinkler irrigation systems.

  3. Monitor pH and EC to ensure optimal nutrient absorption.

Step 4: Safety Measures

  • 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.


Quick Application Guide

StepActionRecommended Dosage/Condition
1Soil TestingDetermine Mg deficiency levels
2Equipment SetupClean and calibrate spreaders or fertigation system
3Powder Application100–200 kg/ha for soil; 1–2% solution for fertigation
4IncorporationLightly mix into topsoil (2–5 cm)
5MonitoringCheck 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.
