The best way to determine if you need more Bone Meal is through soil test but if that's not available or cost effective then I recommend monitoring the leaves of your rose plants for phosphorous deficiency signs and add more Bone Meal if you see any phosphorous deficiency signs.

Yes, Ammonium Sulfate is excellent for blueberries. Here's why:

• Best source: It's one of the best and most affordable Ammoniacal Nitrogen sources.
• Preferred form: Blueberries thrive on Ammonia-based Nitrogen.
• Avoid Nitrates: Blueberries are sensitive to nitrate ions, which can damage them.

Caution:

Apply carefully: Blueberries are sensitive to over-fertilization.

Follow rates: Excess Nitrogen can harm or kill plants.

For foliar application of Ammonium Sulfate:

1. Dissolve 1-3 tablespoons per gallon of water
2. Use lower concentration for sensitive plants
3. Apply early morning or late evening to prevent leaf burn
Test on a small area first

Caution:

Concentration may vary based on plant type and growth stage
Over-application can damage leaves.

Yes, Ammonium Sulfate can significantly improve onion bulb growth:

• Nitrogen boost: Provides essential nitrogen for robust leaf and bulb development
• Sulfur benefit: Sulfur in Ammonium Sulfate enhances onion flavor and size

Application tips:

A 25-pound bag of Ammonium Sulfate typically covers:

• Approximately 5,000 square feet of Bermuda grass
• Application rate: 5 pounds per 1,000 square feet

Key points:

This is a general guideline for established Bermuda grass. Actual coverage may vary based on soil conditions and grass health. Apply evenly and water thoroughly after application

Fertilizers usually have 3 numbers, first one is a percentage of Nitrogen (N), the second one is a percentage of Phosphorous (P) and the third one is Potassium (K).

We also have different kinds of nitrogen such as Ammonia and Nitrate and as it is obvious from the name Ammonium Sulfate contains 21% Ammoniacal Nitrogen, which is readily available nitrogen for plants.

In addition, Greenway Biotech, Inc. Ammonium Sulfate contains 24% Sulfur (S) which is one of the most important secondary nutrients.

Please note that 21% Nitrogen is not the highest nitrogen fertilizer (for example, Urea 46-0-0 contains 46% nitrogen) but it is a relatively high nitrogen fertilizer.

No, Ammonium Sulfate is not an oxygen scavenger and you need Ammonium Sulfite for that.

Apply 5 pounds per 1,000 sq.ft. or 200 pounds per acre (application at the recommended rates will last about 4 to 6 weeks).

Is Ammonium Sulfate safe for pets? Can the pets go on my lawn after I used this fertilizer on my lawn?

Ammonium sulfate can be used safely as a fertilizer for lawns, but precautions should be taken to ensure the safety of pets. Here’s what you need to know:

Safety Considerations for Pets:

1. Immediate Exposure:

• Application: When ammonium sulfate is first applied, it can be irritating to pets if they come into direct contact with it. This is particularly true if the granules are still visible on the surface.
• Skin and Paw Irritation: Direct contact with the granules can cause irritation to the skin and paws of pets.

2. Post-Application:

• Watering In: It’s generally advised to water the lawn thoroughly after applying ammonium sulfate. This helps dissolve the fertilizer and moves it into the soil, reducing the risk of direct contact.
• Waiting Period: After watering, it’s best to wait until the lawn is completely dry before allowing pets to roam freely. This reduces the likelihood of irritation or ingestion of the fertilizer.

3. Ingestion Risks:

• Eating Grass: If pets consume grass treated with ammonium sulfate before it has been watered in and absorbed, it can cause gastrointestinal upset, including vomiting and diarrhea.
• Pet Safety Measures: To minimize risks, keep pets off the treated lawn for at least 24-48 hours after application and watering.

Can Ammonium Sulfate be applied with a broadcast spreader and watered in, or is a tank sprayer necessary?

You can apply ammonium sulfate using either a tank sprayer or a broadcast spreader, but the method you choose can depend on the form of ammonium sulfate you are using and your specific needs.

Broadcast Spreader

• Granular Form: Ammonium sulfate is often available in granular form, which is ideal for use with a broadcast spreader.
• Application Process:
  1. Spread Evenly: Use the broadcast spreader to apply the granules evenly over the lawn.
  2. Water In: After application, water the lawn thoroughly to dissolve the granules and help the fertilizer penetrate the soil.
• Benefits: Using a broadcast spreader is straightforward, allows for even distribution, and is suitable for larger areas.

Tank Sprayer

• Dissolved Form: If you prefer to apply ammonium sulfate in liquid form, you can dissolve the granules in water and use a tank sprayer.
• Application Process:
  1. Mix Solution: Dissolve the appropriate amount of ammonium sulfate in water.
  2. Spray Evenly: Use the tank sprayer to apply the solution evenly over the lawn.
• Benefits: This method can provide more immediate results as the nutrients are more readily available for plant uptake, and it is useful for targeted applications or smaller areas.

Considerations

• Watering: Regardless of the application method, it is crucial to water the lawn thoroughly after applying ammonium sulfate to help move the fertilizer into the soil and prevent any potential leaf burn.
• Equipment Cleaning: If using a tank sprayer, ensure it is cleaned thoroughly after use to prevent corrosion or damage from the ammonium sulfate solution.

Yes, ammonium sulfate is suitable for Zoysia grass. Here’s how it can be beneficial and how to use it effectively:

Benefits for Zoysia Grass

• Nitrogen Source: Ammonium sulfate provides a readily available source of nitrogen, which promotes lush, green growth and helps maintain the dense, carpet-like appearance of Zoysia grass.
• Soil Acidity: Ammonium sulfate can lower the pH of the soil, which is beneficial for Zoysia grass that prefers slightly acidic to neutral soil (pH 6.0 to 6.5).

Application Guidelines

• Timing:
  1. Spring: Apply in early spring as the grass begins to green up and grow actively.
  2. Summer: A second application can be made in mid-summer to maintain growth and color.

• Rate:
  1. Recommended Rate: Apply at a rate of 1 pound of nitrogen per 1,000 square feet. For ammonium sulfate (21-0-0), this translates to approximately 4.7 pounds of ammonium sulfate per 1,000 square feet.
  2. Frequency: Limit applications to 2-3 times per year to avoid excessive growth and potential thatch buildup.

• Application Method:
  1. Broadcast Spreader: Use a broadcast spreader to apply the ammonium sulfate evenly over the lawn.
  2. Watering In: After application, water the lawn thoroughly to help the fertilizer penetrate the soil and to prevent potential leaf burn.
  
• Precautions:
  1. Avoid Over-application: Over-fertilizing can lead to excessive growth, thatch buildup, and potential damage to the grass.
  2. Check Soil pH: Regularly monitor soil pH to ensure it stays within the optimal range for Zoysia grass.

Yes, ammonium sulfate can be suitable for pomegranate trees, but it should be used with care. Here are some key points to consider:

Benefits of Ammonium Sulfate for Pomegranate Trees:

• Nitrogen Source: Ammonium sulfate provides nitrogen, which is essential for the growth and development of pomegranate trees. Nitrogen promotes healthy foliage and overall tree vigor.
• Sulfur Source: It also supplies sulfur, which is a secondary nutrient important for protein synthesis and enzyme function in plants.

Considerations for Using Ammonium Sulfate:

• Soil pH: Ammonium sulfate can lower soil pH because it is acidic. Pomegranate trees prefer slightly acidic to neutral soil (pH 5.5 to 7.0). If your soil is already on the acidic side, using ammonium sulfate may further lower the pH to undesirable levels. It’s important to monitor soil pH regularly.
• Application Rate: Use ammonium sulfate at appropriate rates to avoid over-fertilization, which can harm the trees.

Application Guidelines:

• Soil Test: Conduct a soil test to determine the current nutrient levels and pH. This will help you decide the appropriate amount of ammonium sulfate to apply.
• Application Rate: A general recommendation for ammonium sulfate is to apply 1 pound per inch of trunk diameter, distributed evenly around the tree’s drip line. This should be done once or twice during the growing season.
• Timing: Apply in early spring when new growth begins and possibly again in late spring or early summer. Avoid late-season applications that might encourage growth that can be damaged by frost.
• Watering: After applying ammonium sulfate, water the area thoroughly to help dissolve the fertilizer and move it into the root zone.

Yes, you can grow crystals using ammonium sulfate. Ammonium sulfate crystals are relatively easy to grow and can be a fun and educational project.

Yes, ammonium sulfate can be a good fertilizer for evergreens, but it should be used with care. Here are some key points to consider:

Benefits of Ammonium Sulfate for Evergreens:

• Nitrogen Source: Ammonium sulfate provides a high amount of nitrogen, which is essential for the growth and vibrant green color of evergreen foliage.
• Sulfur Source: It also supplies sulfur, which is necessary for protein synthesis and overall plant health.

Considerations for Using Ammonium Sulfate:

• Soil pH: Ammonium sulfate is acidic and can lower soil pH. Evergreens generally prefer slightly acidic to neutral soil (pH 5.5 to 6.5). If your soil is already acidic, using ammonium sulfate might lower the pH too much.
• Application Rate: Proper application rates are crucial to avoid over-fertilization, which can harm evergreens.

Application Guidelines:

• Soil Test: Conduct a soil test to determine the current nutrient levels and pH. This will help you decide the appropriate amount of ammonium sulfate to apply.
• Application Rate: Apply 1/2 to 1 pound of ammonium sulfate per 100 square feet of soil area. Adjust according to soil test recommendations.
• Timing: Apply in early spring when new growth begins and possibly again in mid-summer. Avoid late-season applications to prevent new growth that could be damaged by frost.

Method:

• Spread Evenly: Distribute the ammonium sulfate evenly around the base of the evergreens, extending to the drip line.
• Water In: After application, water the area thoroughly to help dissolve the fertilizer and move it into the root zone.
