Nitrogen Western Australia . Key Points. Nitrogen (N) is needed for crop growth in larger quantities than any other nutrient. Nitrate (NO 3) is the highly mobile form of inorganic nitrogen in both the soil and the plant.; Sandy soils in high rainfall areas are most susceptible to nitrate loss through leaching.
