How to Increase Nitrogen in Soil Nick Vasco | 4 minutes | February 4, 2025 You can increase nitrogen in soil through various methods, with organic matter addition and specialized nitrogen-rich products being the most effective. In this guide, we’ll explain these two methods in more detail and discuss a few other effective approaches you should try. Tip: Check out WestAir’s nitrogen services. The Power of Organic Matter: Nature’s Nitrogen Factory Adding organic matter is the most natural and sustainable way to increase soil nitrogen. When organic materials break down, they release nitrogen in forms that plants can easily absorb. Compost is your best friend here. Spread a 2-3 inch layer on your soil, work it in, and microorganisms will do the rest. They’ll break down the organic matter and release nitrogen slowly over time. Animal manure is another excellent source of nitrogen – but timing is crucial. You’ll want to compost it for about six months before use. For a 100-square-foot area, you can use any of the following: 70 pounds of chicken manure 200 pounds of cow manure 65 pounds of horse manure Everyday Items That Pack a Nitrogen Punch If you don’t have enough organic matter readily available, fret not – common household items can also boost soil nitrogen levels. For example, coffee grounds can be a valuable nitrogen source for plants. You can mix them into your compost pile or sprinkle them directly around your plants in small doses. Keep in mind that they’re acidic, though, so use them sparingly around plants that don’t like low pH. Fresh grass clippings also make an excellent nitrogen-rich mulch. Let them dry slightly before applying to prevent matting, and avoid using clippings from lawns treated with chemicals. Professional-Grade Solutions for Serious Results If you need more controlled and precise nitrogen enhancement, you can choose from several specialized options: Blood meal: provides fast-acting nitrogen that plants can use almost immediately. Apply about one pound per 100 square feet, but be careful not to overdo it. Alfalfa meal: another excellent option offering a steady release of nitrogen. Use 2-5 pounds per 100 square feet for optimal results. Feather meal: a longer-term solution that breaks down slowly, providing sustained nitrogen release. Apply 2-3 pounds per 100 square feet around your plants. The Strategic Use of Cover Crops Cover crops are an excellent long-term strategy for improving soil nitrogen levels. This method is particularly effective for larger areas and commercial applications. Legumes like peas and beans work with beneficial bacteria to fix nitrogen from the air into the soil. When these plants die or are tilled under, they release this stored nitrogen. You can also plant alfalfa or clover as cover crops. These plants not only fix nitrogen while growing, but also provide additional nitrogen when chopped and incorporated into the soil. Fertigation Systems: Modern Solutions for Advanced Users For commercial operations or serious gardeners, fertigation systems offer a precise way to deliver nitrogen to your soil. They combine fertilization with irrigation, allowing for exact control over nitrogen application. Fertigation provides consistent nitrogen levels while saving time and labor. It’s particularly useful for large-scale operations where manual application methods might be impractical. Nurture Your Soil Beyond Nitrogen Healthy soil is the foundation of successful growing. While adding nitrogen is important, it’s just one part of maintaining proper soil health. Regular soil testing can help you determine exactly how much nitrogen or other elements your soil needs. By implementing the methods you saw above, you can ensure your soil has the nitrogen it needs for optimal plant growth. Whether you choose organic methods, specialized products, or modern fertigation systems, the key is consistency and careful monitoring of your soil’s needs.
