This 22- by 17-inch poster features photographs of nutrient deficiencies in six important crop plants: corn, soybeans, rice, cotton, wheat and alfalfa. It also includes a diagram of five steps in plant tissue testing. The back of the poster has a laboratory exercise for teachers to use.



The learning objectives for the exercise are to:

  • Become familiar with the essential plant nutrients and their functions in plants
  • Recognize characteristic visual symptoms of nutrient deficiency in plants
  • Learn about hydroponic systems and the use of nutrient solutions.
