Answer:
changed to ammonia (NH3) by bacteria in the soil and attached to the roots of legumes (peas, beans, peanuts and soybeans). A few plants can use ammonia but most cannot. Through the process of nitrification, this problem is solved. Nitrifying bacteria change the ammonia in the soil to nitrites and then into nitrates.
