All of the listed processes can lead to the loss of nitrogen from the soil. Erosion physically removes topsoil that contains nitrogen compounds. Leaching by water can wash away soluble nitrogen compounds deeper into the soil, away from plant roots. Harvesting crops removes nitrogen that was incorporated into plant tissues, and fire can volatilize nitrogen, converting it into gases that escape into the atmosphere.
