Wicked Organics Sul-Po-Mag TRIO OMRI

How to Apply Sul-Po-Mag TRIO OMRI 00-0-22 22% Mg

To effectively use Sul-Po-Mag TRIO OMRI 00-0-22 22% Mg, a natural mineral fertilizer providing potassium (22%), magnesium (22%), and sulfur (~11%), follow these steps to address nutrient deficiencies and support plant health:

  1. Assess Nutrient Needs: Conduct a soil test to confirm deficiencies in potassium, magnesium, or sulfur (e.g., yellowing leaves for magnesium, weak stems for potassium). This ensures targeted application.

  2. Determine Application Rate: Apply 5–10 pounds per 1,000 square feet for gardens or lawns, 1–2 pounds per inch of trunk diameter for trees/shrubs, or 1–2 tablespoons per gallon of potting mix for containers. Adjust based on soil test results and label instructions.

  3. Timing: Apply in early spring or fall during active plant growth or pre-dormancy to maximize nutrient uptake. Avoid application before heavy rain to prevent runoff.

  4. Application Method:

    • Gardens/Lawns: Broadcast evenly using a spreader, then lightly incorporate into the top 2–4 inches of soil.

    • Trees/Shrubs: Spread under the canopy, avoiding direct contact with trunks, and work into the soil.

    • Containers: Mix into potting soil before planting or apply as a top dressing and water in.

  5. Watering: Water thoroughly after application (about 1/4–1/2 inch of water) to dissolve granules and facilitate nutrient uptake by roots.

  6. Safety Precautions: Wear gloves and, if needed, a mask to avoid dust inhalation. Keep pets and children away until watered in and dry. Store in a sealed container in a cool, dry place.

  7. Monitoring: Observe plants over weeks for improved vigor (e.g., greener leaves, stronger stems). Adjust future applications based on soil tests to avoid nutrient imbalances.

Follow manufacturer guidelines to ensure effective use and minimize environmental impact.

FAQ About Sul-Po-Mag TRIO OMRI 00-0-22 22% Mg

What is it made of?

Sul-Po-Mag TRIO OMRI 00-0-22 22% Mg is primarily composed of langbeinite, a naturally occurring mineral mined from ancient sea deposits. It provides:

  • Potassium (22% K2O): Supports water regulation, enzyme activation, and stress resistance.

  • Magnesium (22% Mg): Essential for chlorophyll production and photosynthesis.

  • Sulfur (~11%): Aids in protein synthesis and enzyme function.


    Its natural composition makes it suitable for organic farming.

Is it organic or OMRI-listed?

Sul-Po-Mag TRIO is OMRI-listed, confirming its compliance with USDA organic standards for use in certified organic production. It is derived from natural mineral sources.

What is the NPK ratio?

The NPK ratio is 00-0-22, indicating 0% nitrogen (N), 0% phosphorus (P), and 22% potassium (K as K2O), with an additional 22% magnesium for plant health.

Does it contain secondary nutrients?

Yes, it contains two secondary nutrients:

  • Magnesium (22%): Supports chlorophyll production and nutrient uptake.

  • Sulfur (~11%): Enhances protein synthesis and plant resilience.

Does it provide micronutrients?

It primarily provides potassium, magnesium, and sulfur, with no significant micronutrients (e.g., iron, zinc, boron) unless specified on the label. Supplement with micronutrient-specific products if needed.

What is the form (granular, powder, liquid)?

Sul-Po-Mag TRIO is typically granular, allowing easy application and slow nutrient release into the soil.

Is it natural or processed?

It is a natural product, mined from langbeinite deposits with minimal processing to maintain its organic certification and nutrient content.

Is it synthetic-free?

Yes, it is synthetic-free, as confirmed by its OMRI listing and natural langbeinite composition, making it suitable for organic farming.

What is it used for?

Sul-Po-Mag TRIO is used to:

  • Supply potassium for water regulation, disease resistance, and yield quality.

  • Provide magnesium for photosynthesis and nutrient uptake.

  • Deliver sulfur for protein synthesis and stress resilience.

  • Correct deficiencies in potassium, magnesium, or sulfur in organic farming systems.

What plants or crops is it best for?

It is best for:

  • Fruit Trees/Vines: Apples, citrus, grapes for fruit quality and vigor.

  • Vegetables: Tomatoes, potatoes, peppers for growth and yield.

  • Nut Trees: Almonds, pecans for nut development.

  • Field Crops: Corn, soybeans, wheat in potassium/magnesium-deficient soils.

  • Ornamentals: Roses, azaleas for flowering and foliage health.

  • Lawns/Turf: Enhances grass health and stress resistance.

What is the recommended application rate?

  • Gardens/Lawns: 5–10 pounds per 1,000 square feet.

  • Trees/Shrubs: 1–2 pounds per inch of trunk diameter.

  • Containers: 1–2 tablespoons per gallon of potting mix.


    Adjust based on soil tests and label instructions.

How often should it be applied?

Apply once at the start of the growing season (spring) for most crops. For high-demand crops or deficient soils, a mid-season application may be needed. Use soil tests to guide frequency.

Does it need to be mixed with other amendments?

It may need supplementation if soil tests show deficiencies in nitrogen, phosphorus, or other nutrients. Add lime or sulfur for pH adjustments or organic matter for soil structure.

Is pre-charging required before use?

No pre-charging is required. Apply directly to soil and water in for immediate nutrient availability, following label instructions.

Is it suitable for containers, raised beds, or field crops?

  • Containers: Suitable for nutrient balance in limited soil volumes.

  • Raised Beds: Enhances fertility for vegetables and ornamentals.

  • Field Crops: Effective for potassium/magnesium-hungry crops in organic systems.

What are the expected plant growth benefits?

  • Potassium: Enhances water regulation, stress resistance, and yield quality.

  • Magnesium: Boosts chlorophyll production for photosynthesis and green foliage.

  • Sulfur: Supports protein synthesis and disease resistance.

  • Overall: Improves plant vigor, yield, and resilience.

Does it improve soil structure?

It has minimal direct impact on soil structure but indirectly supports it via enhanced plant growth and root development. Add organic matter (e.g., compost) for significant structural improvements.

Does it enhance water retention?

It does not directly enhance water retention but supports plant health, improving water uptake. Use organic amendments like compost for better moisture retention.

Does it improve nutrient holding capacity?

It does not significantly improve nutrient holding capacity. Organic matter or biochar is more effective for enhancing soil’s cation exchange capacity.

Does it support microbial life?

It indirectly supports microbial life by improving plant health and root exudates, which feed microbes. It does not directly provide organic matter for microbial growth.

Does it buffer pH or improve soil chemistry?

It is pH-neutral and does not buffer pH but improves soil chemistry by supplying potassium, magnesium, and sulfur. Use lime or sulfur for pH adjustments.

How fast does it work?

Nutrients dissolve and become available within weeks, with effects visible in plant vigor over 2–4 weeks, depending on soil moisture and temperature.

Does it help reduce runoff or leaching?

Its balanced nutrient release and soil incorporation reduce runoff/leaching risks. Proper application based on soil tests further minimizes environmental impact.

Is it safe for pets and children?

Safe with precautions:

  • Keep pets/children away during application until watered in and dry.

  • Store securely to prevent ingestion, which may cause mild irritation.

  • Follow label safety instructions.

Does it have an odor?

It has little to no odor, as it is a mineral-based product without organic decomposition smells.

Is it USDA Organic compliant?

Yes, it is USDA Organic compliant, as confirmed by its OMRI listing, ensuring suitability for certified organic production.

Is it safe for edible plants?

Yes, it is safe for edible plants, as it is OMRI-listed and natural. Follow application guidelines to ensure plant safety and produce quality.

Are there environmental risks?

Minimal risks if used correctly:

  • Runoff: Over-application may cause potassium runoff, leading to water pollution.

  • Soil Imbalance: Excessive use may disrupt nutrient balance.


    Mitigate with soil tests and proper application rates.

What is the packaging type?

Typically available in 50-pound bags, common for agricultural fertilizers. Confirm with the supplier for exact packaging options.

How long does it last once applied?

Nutrients remain available for several months, typically a growing season, depending on soil type, weather, and plant uptake. Reapply based on soil tests.

How should it be stored?
