The resulting matches were then boxed up ready to be sold. Hennig named the new substance phosphorus, after the Greek for light bearer. Nitrogen is a key component in proteins and phosphorous is found in deoxyribonucleic acid (DNA), and ribonucleic acid (RNA). A) gases only B . Although total soil phosphorus is generally high, with concentrations ranging from 200 to 6,000 pounds per acre, 80 percent of this phosphorus is immobile and not available for uptake by the plant.
