The Best Organic Nitrogen Fertilizers for Buffalo Grass

Buffalo grass (Buchloe dactyloides) is a popular choice for lawns and landscaping in various regions of the United States, particularly in areas with low rainfall and full sun. This hardy, drought-resistant grass requires a specific care regimen to maintain its vibrant green color and healthy growth throughout the growing season. One critical component of buffalo grass care is fertilization, particularly nitrogen fertilization, which plays a vital role in promoting lush growth and maintaining a robust lawn. Organic nitrogen fertilizers are an excellent choice for this purpose, as they provide nutrients without harming the environment. In this article, we'll explore the best organic nitrogen fertilizers specifically suited for buffalo grass, along with guidelines on how to use them effectively.

Why Choose Organic Fertilizers?

Organic fertilizers are derived from natural sources, such as plant materials, animal manure, and compost. Unlike synthetic fertilizers, organic options improve soil health and structure, fostering beneficial microbial activity which promotes nutrient availability. Additionally, they release nutrients at a slower, more controlled rate, reducing the risk of nutrient runoff and environmental pollution. Choosing organic fertilizers aligns with sustainable gardening practices and contributes to the long-term health of your buffalo grass lawn.

Best Organic Nitrogen Fertilizers for Buffalo Grass

1. Composted Manure One of the oldest and most effective organic fertilizers is composted manure, particularly from herbivores like cows or horses. Composted manure is rich in nitrogen and other essential nutrients needed for buffalo grass growth. When using composted manure, ensure it is well-aged to avoid burning the grass and to reduce weed seeds. Apply it in the spring when the grass starts to grow, using a thin layer to provide a steady supply of nitrogen.

2. Blood Meal Blood meal, a byproduct of the meat industry, is a high-nitrogen organic fertilizer with around 12-15% nitrogen content. It's an excellent option for a quick nitrogen boost, making it ideal for early spring applications when buffalo grass begins to green up. However, it should be used sparingly to avoid unbalanced nutrient levels. Typically, about 1 to 2 lbs per 100 square feet is sufficient.

3. Soybean Meal Soybean meal is a popular choice among organic gardeners due to its balanced nutrient profile. It contains around 6-7% nitrogen, along with phosphorus and potassium. This slower-releasing fertilizer provides a gradual nitrogen supply, essential for prolonged growth. Apply soybean meal in early spring and again in late summer to sustain grass health during the growing season.

4. Alfalfa Meal Alfalfa meal is another excellent organic option, rich in nitrogen (approximately 3-4% nitrogen) and beneficial growth hormones known as triacontanol, which can stimulate grass growth. It also enhances soil microbial activity. Similar to soybean meal, alfalfa meal can be applied in the spring and late summer. A general recommendation is to use 1-2 lbs per 100 square feet.

5. Fish Emulsion Fish emulsion is a liquid organic fertilizer that provides a quick nitrogen boost to plants. It typically contains 5-2-2 NPK ratio, making it an excellent option for buffalo grass. Its nutrient content is rapidly absorbed by plants, promoting quick growth. Dilute the fish emulsion according to package instructions and apply it every 4-6 weeks during the growing season for optimal results.

Application Guidelines

When applying organic nitrogen fertilizers to buffalo grass, it’s crucial to follow a few key practices

- Timing Apply fertilizers during the active growing season, preferably in the early spring and late summer. - Soil Testing Conduct a soil test to determine current nutrient levels, helping you choose the right fertilizer and avoid over-application. - Watering Water your lawn thoroughly after applying organic fertilizers to help with nutrient absorption and prevent any potential burn.

Conclusion

In conclusion, healthy buffalo grass lawns thrive on organic nitrogen fertilizers that enhance growth while promoting soil health. Composted manure, blood meal, soybean meal, alfalfa meal, and fish emulsion are all excellent choices that provide essential nutrients for your lawn while aligning with environmentally friendly practices. By applying these fertilizers appropriately and following best practices, you can achieve a lush, vibrant buffalo grass lawn that thrives in your landscape.
