How to make nitrogen fertilizer 
Use compost. 
Compost is nothing more than decomposed organic matter. The average compost pile contains a plethora of beneficial nutrients, including potassium, phosphorus, and nitrogen.

Choose your answer from: (1). Regarding nitrogen, the bacteria in compost break matter down into ammonium, which is then naturally converted by other bacteria into nitrates that plants can absorb through their roots. Compost high in nitrogen materials, including moist greens, fruits, and vegetables, tends to provide the highest content of nitrogen to the soil bed it is applied to. (2). Manure with sufficient nitrogen is your best bet for nitrogen fertilizer. If a pile of loosely composted compost contains hundreds or thousands of plants, you should avoid using compost as it is the top fertilizer for the garden. (3). Aim to repot manure every 4-6 months. For cloche, your compost pile should be as much compost as you intend to root your plant. (4). You can mix it up and feed it to your plants through the cuttings that are grown inside. Keep in mind that you can plant a pile of compost in a drier area that isn't the same temperature as your surrounding environment.
