Describe the three most important plant minerals
What will be an ideal response?
The three important plant minerals are nitrogen, phosphorus, and potassium. Most Nitrogen is produced synthetically
from air. Phosphorous is found in the earth's crust in the form of phosphate rock. Potassium is often called
"potash" due to the early incidental use of potassium. It was discovered that when boiled wood ashes from pots
were applied to crops, they grew better. It was later discovered the substance was potassium. In nature, potassium
occurs in the form of salts in beds similar to coal. Along with the production of potash from mines, potassium can
be obtained from desalination processing of seawater.
