Usable forms of nitrogen can intentionally be increased in the soil by

Answer 1

adding nitrogen fertilizers like ammonium nitrate, urea or ammonium sulfate. These fertilizers provide the necessary nutrients for the plants to grow, including nitrogen in a form that can be easily taken up by the plant's roots. Additionally, planting nitrogen-fixing crops like beans, peas, or clover, can increase the amount of usable nitrogen in the soil as these crops have specialized bacteria which form nodules on their roots that convert atmospheric nitrogen into a form plants can use. Finally, composting organic material and using it as a soil amendment can also increase the soil's nitrogen content.
