How Magnesium Nitrate Provides Rapid Magnesium Nutrition for Crops

Technical Introduction

Magnesium nitrate (Mg(NO₃)₂) is a highly water-soluble magnesium salt that supplies both magnesium (Mg) and nitrate nitrogen (NO₃⁻) to plants.
It is commonly used in fertigation, foliar feeding, and hydroponic systems.
Magnesium is essential for chlorophyll synthesis, enzyme activation, and photosynthesis, while nitrate provides a readily available nitrogen source for plant growth.

Applications

1. Agriculture & Horticulture

• Micronutrient Fertilizer: Corrects magnesium deficiencies in crops like vegetables, fruits, and cereals.

• Foliar Spray: Provides rapid magnesium and nitrogen uptake.

• Hydroponics & Fertigation: Highly soluble, ideal for nutrient solutions.

2. Industrial Uses

• Chemical Production: Precursor for magnesium-based chemicals and explosives.

• Laboratory Reagent: Used in analytical chemistry and chemical synthesis.

Advantages

• Highly Soluble: Quickly available for plant uptake.

• Dual Nutrient Source: Supplies magnesium and nitrate nitrogen simultaneously.

• Rapid Correction: Ideal for foliar and fertigation applications to address deficiencies quickly.

• Versatile: Suitable for soil, foliar, and hydroponic systems.

Typical Parameters

FAQs

Q1: How is magnesium nitrate different from magnesium sulfate?
A1: Magnesium nitrate provides both Mg and nitrate nitrogen, while magnesium sulfate provides Mg and sulfur; nitrate also acts as a fast nitrogen source.

Q2: Can it be used as a foliar spray?
A2: Yes, typically at 0.5–1% solution for rapid correction.

Q3: Is it safe for crops and hydroponic systems?
A3: Yes, when applied according to recommended rates.

Q4: How fast does it correct magnesium deficiency?
A4: Foliar applications show visible improvement within days; soil applications may take slightly longer.

Q5: How should it be stored?
A5: Keep in a dry, cool, ventilated area to avoid caking and moisture absorption.
