What Is Milorganite? Unveiling the Magic Behind the Fertilizer

Milorganite isn’t your average fertilizer. It’s a slow-release, organic nitrogen fertilizer produced by the Milwaukee Metropolitan Sewerage District (MMSD). What makes it special? It’s made from heat-dried microbes that have digested the organic matter in wastewater. This process transforms waste into a valuable resource, offering a sustainable and environmentally friendly approach to lawn care. It’s been around for nearly a century, proving its effectiveness over and over again.

Key Characteristics of Milorganite:

• Slow-Release Nitrogen: Provides a steady supply of nutrients, reducing the risk of burning your lawn.
• Organic: Derived from recycled materials, making it a more environmentally friendly choice.
• Iron Content: Contains iron, which helps promote a rich, green color in your lawn.
• Non-Burning: Safe for various grass types and won’t harm your lawn if applied incorrectly.
• Improves Soil Health: Adds organic matter to the soil, improving its structure and water retention.

The Npk Ratio: Understanding the Numbers

Like all fertilizers, Milorganite has an NPK ratio. This ratio represents the percentage of Nitrogen (N), Phosphorus (P), and Potassium (K) in the fertilizer. The NPK ratio on Milorganite is typically 6-4-0. This means it contains 6% nitrogen, 4% phosphorus, and 0% potassium. Because of the low phosphorus and zero potassium, it’s ideal for established lawns that may not need extra phosphorus or potassium. It’s also important to note that the exact ratios can vary slightly from batch to batch, but they generally hover around this formulation. For new lawns or those with specific soil deficiencies, you might need to supplement with other fertilizers to address those needs. A soil test is always a good idea.

The Benefits of Using Milorganite

Why choose Milorganite over other fertilizers? The benefits are numerous:

• Environmentally Friendly: Made from recycled materials, reducing waste and promoting sustainability.
• Slow-Release: Provides a consistent supply of nutrients, promoting healthy growth without the risk of burning.
• Improves Soil Health: Adds organic matter, improving soil structure and water retention.
• Safe for Pets and Children: The non-burning nature makes it safe for areas where pets and children play.
• Weed Suppression: Can help to reduce weed growth by promoting a thick, healthy lawn that crowds out weeds.
• Easy to Apply: Can be applied with a spreader, making it convenient for homeowners.

How to Use Milorganite Fertilizer: A Step-by-Step Guide

Now that you understand what Milorganite is and why it’s a great choice, let’s get into the how-to. Applying Milorganite is straightforward, but following these steps will ensure optimal results.

1. Assess Your Lawn: Before you start, take a good look at your lawn. What type of grass do you have? Are there any bare spots or areas that need extra attention? This will help you determine the appropriate amount of Milorganite to use. Also, consider a soil test. This will tell you if your lawn has any specific nutrient deficiencies.
2. Choose the Right Time: The best times to apply Milorganite are during the growing season. This generally means spring and fall. These are the periods when your grass is actively growing and can best utilize the nutrients. Avoid applying during the heat of summer or when the ground is frozen.
3. Calculate the Application Rate: The general recommendation is to apply Milorganite at a rate of 1 pound per 100 square feet. This is a good starting point. However, always read and follow the instructions on the product label, as specific recommendations may vary.
4. Choose Your Application Method: Milorganite can be applied using a broadcast spreader or a drop spreader. A broadcast spreader is ideal for larger lawns, while a drop spreader is better for smaller areas or lawns with obstacles.
5. Calibrate Your Spreader: Before applying, calibrate your spreader to ensure you’re applying the correct amount of fertilizer. Refer to the spreader’s instructions for calibration.
6. Apply the Fertilizer: Fill the spreader with Milorganite. Walk at a consistent pace, overlapping each pass slightly to ensure even coverage.
7. Water Thoroughly: After applying Milorganite, water your lawn thoroughly. This helps the fertilizer penetrate the soil and activates the slow-release action.
8. Repeat as Needed: Depending on your lawn’s needs, you can apply Milorganite every 6-8 weeks during the growing season. Always monitor your lawn’s health and adjust the application schedule as needed.

Detailed Application Instructions

Let’s break down each step in a little more detail:

1. Assessing Your Lawn: Take notes about your lawn’s condition. Note any bare spots, weed problems, or areas that seem to struggle. Also, identify your grass type (e.g., Kentucky bluegrass, fescue, Bermuda). Different grass types have slightly different nutrient needs.
2. Timing is Key: For most regions, spring (early to mid-spring) and fall (early to mid-fall) are the ideal times. Spring applications help your lawn green up and recover from winter. Fall applications help build strong roots for the winter and promote healthy growth the following spring. Avoid applying Milorganite just before heavy rains, as it can wash away before it’s absorbed.
3. Calculating the Amount: The general rule is 1 pound of Milorganite per 100 square feet. To calculate the total amount needed, measure the length and width of your lawn (or the area you want to fertilize) and multiply them to get the square footage. For example, if your lawn is 50 feet by 100 feet, it’s 5,000 square feet. Therefore, you would need 50 pounds of Milorganite (5,000 / 100 = 50). Always double-check the product label for specific instructions.
4. Choosing the Right Spreader:
   • Broadcast Spreaders: These are great for larger lawns because they distribute the fertilizer over a wide area. They typically have adjustable settings to control the application rate.
   • Drop Spreaders: These are better for smaller lawns or areas where you need more precision, such as around flower beds or trees. They drop the fertilizer directly below the spreader, preventing overspray.
5. Calibrating Your Spreader: This is crucial! Most spreaders have a dial or setting to control the flow rate. Refer to the spreader’s instructions. You may need to do a test run on a small, measured area to see how much fertilizer is dispensed at a specific setting.
6. Applying the Fertilizer: Start by walking along the perimeter of your lawn and then work your way in. Overlap each pass by a few inches to ensure even coverage. Avoid turning sharply while the spreader is dispensing fertilizer, as this can lead to uneven distribution.
7. Watering After Application: Water the lawn thoroughly after applying Milorganite. This helps the fertilizer reach the soil and begin to break down, releasing nutrients to the grass roots. Aim for about 1/2 inch of water.
8. Repeating the Process: Depending on the needs of your lawn, you can reapply Milorganite every 6-8 weeks during the growing season. Monitor the lawn’s health (color, growth rate, weed presence) and adjust the application schedule accordingly. Avoid over-fertilizing, as this can be harmful to your lawn.

Troubleshooting Common Issues

Even with the best intentions, things can go wrong. Here’s how to address some common issues:

• Uneven Green Patches: This can be caused by uneven fertilizer distribution. Ensure your spreader is calibrated correctly and that you are overlapping passes.
• Yellowing Grass: This could be a sign of over-fertilization, or possibly a lack of water. Stop fertilizing immediately and water the lawn deeply. If the problem persists, consider a soil test to check for nutrient imbalances.
• Weed Problems: While Milorganite can help suppress weeds, it’s not a weed killer. If you have a significant weed problem, consider using a pre-emergent herbicide in the spring or a post-emergent herbicide to target existing weeds.
• Slow Results: Milorganite is a slow-release fertilizer, so it may take a few weeks to see noticeable results. Be patient and give the fertilizer time to work. Also, make sure you’re watering your lawn regularly.
• Strong Odor: Milorganite has a distinct, earthy odor. This is normal and will dissipate within a few days of application. If the odor is overwhelming, you may have applied too much fertilizer.
