Manganese Sulfate Fertilizer

Prevent and correct nutrient deficiencies with Manganese Sulfate Fertilizer, a high-purity, fully water-soluble micronutrient source. Delivering a potent 31% elemental manganese and 18% sulfur, it is one of the most concentrated and effective ways to restore vibrant plant health.

Manganese is an essential driver for photosynthesis, nitrogen metabolism, and chlorophyll function. Because it is immobile within the plant, a deficiency usually appears first as yellowing between the veins of the youngest leaves (interveinal chlorosis). This is especially common in high-pH, sandy, calcareous, or over-limed soils where manganese availability drops sharply.

Ideal For:

  • Palms, citrus, and fruit trees

  • Vegetables, berries, and field crops

  • Turfgrass and hydroponic systems

  • Versatile Application: Dissolves completely and cleanly for use in soil, fertigation, and foliar spraying.

Key Features:

  • High-Purity Formula: Provides 31% elemental Manganese and 18% Sulfur (MnSO₄·H₂O).

  • Tested & Verified: CDFA registered and rigorously third-party lab-tested for heavy metals, consistently testing well below required limits.

  • Sourcing Note: The 50 lb size is repackaged from OMRI Listed® material. All other sizes are CDFA registered but not repackaged from OMRI Listed® material.

Important Handling & Application Rules:

  • Test First: Always confirm the need for manganese with a soil or tissue test before applying.

  • Check Your Soil pH: This product performs best in acidic to neutral soils. For soils with a pH above roughly 7.5, a chelated manganese form is recommended instead.

  • Tank-Mixing Warning: Do not tank-mix with glyphosate. Apply the two products at least three days apart.

  • Safety & Storage: Wear eye protection and minimize dust exposure when handling. Always store tightly sealed in a dry environment.

Frequently Asked Questions

What are the main benefits of using Organic Manganese Sulfate Fertilizer for my plants?
Organic Manganese Sulfate Fertilizer provides a high-purity, water-soluble source of manganese and sulfur, essential for healthy plant growth. It helps prevent deficiencies that cause yellowing leaves and boosts processes like photosynthesis, making your plants more vibrant and productive.
How do I know if my soil needs manganese supplementation?
It's best to confirm nutrient deficiencies with a soil or tissue test before applying Organic Manganese Sulfate Fertilizer. This ensures your plants actually need manganese, helping to optimize application and avoid unnecessary supplementation.
Can I use this fertilizer on all types of soil and plants?
Organic Manganese Sulfate Fertilizer is versatile and suitable for a wide range of plants including palms, citrus, vegetables, berries, turfgrass, and hydroponic systems. However, it performs best in acidic to neutral soils, so checking your soil pH is recommended for optimal results.
What precautions should I take when applying this manganese sulfate fertilizer?
Always wear eye protection and minimize dust exposure during handling. Avoid tank-mixing with glyphosate and always apply at least three days apart from such herbicides. Store the fertilizer in a dry, sealed container to maintain its efficacy.
How should I apply Organic Manganese Sulfate Fertilizer for best results?
The fertilizer can be dissolved completely for use in soil application, fertigation, or foliar spraying. Tailor the application based on your plant’s specific needs, and confirm manganese deficiency before use to ensure effective results.
What are the main benefits of using organic manganese sulfate fertilizer for my plants?
Organic manganese sulfate fertilizer provides essential manganese and sulfur, promoting healthy photosynthesis, nitrogen metabolism, and chlorophyll production. It helps correct deficiencies and restores vibrant plant health, especially in challenging soil conditions.
