                    <li>Add manure: Manure is a simple way to amend your soil with nitrogen. Be cautious as different types of manures have varying nitrogen levels.</li>
                    <li>Coffee grounds: Use coffee grounds as a green compost material rich in nitrogen. As the grounds break down, your soil will be enriched with nitrogen. Additionally, coffee grounds improve drainage.</li>
                    <li>Plant nitrogen-fixing plants: Vegetables in the Fabaceae family, such as peas, beans, and soybeans, can increase nitrogen in your soil.</li>
                    <li>Plant 'green manure' crops: Consider crops like cabbage, corn, and broccoli as green manure to address high nitrogen levels.</li>
                    <li>Use mulch (wet grass): Mulch, including wet grass, sawdust, and soft woods, can help manage nitrogen levels while growing crops.</li>

                <ol>
                    <li>Add sawdust or fine woodchips: The carbon in sawdust/woodchips loves nitrogen and helps absorb excess nitrogen.</li>
                    <li>Plant heavy nitrogen-feeding plants: Tomatoes, corn, broccoli, cabbage, and spinach thrive off nitrogen and can help reduce nitrogen levels in the soil.</li>
                    <li>Water your soil: Soaking your soil with water will help leach nitrogen deeper into the soil, leaving less for plants to use.</li>
                    <li>Sugar: Limited studies suggest that adding sugar to your soil can potentially reduce nitrogen levels. Sugar, being partially composed of carbon, attracts and soaks up nitrogen.</li>
                    <li>Add composted manure: Composted manure is an excellent source of nitrogen for your plants.</li>
                    <li>Plant nitrogen-fixing plants: Consider planting peas or beans to increase nitrogen levels.</li>
                    <li>Use NPK fertilizers with high N value.</li>
                    <li>Do nothing: If you have plants producing lots of foliage, letting them absorb nitrogen may amend the soil for the next crops.</li>

                    <li>Use only phosphorus-free fertilizer: Choose a fertilizer with no phosphorous content, such as a 10-0-10 fertilizer, to provide other key nutrients without increasing phosphorus.</li>
