     QUESTION What are macro and micro nutrients ?

           There are sixteen nutrients which are essential for plants. Air supplies carbon and                     oxygen, hydrogen comes from water, and soil supplies the other thirteen nutrients to                plants. Among these thirteen nutrients, six are required in large quantities and are                 therefore called macro nutrients. The other seven nutrients are used by plants in                       small quantities and are therefore called micro nutrients.
