Match the following Special Techniques Are Used in Nutritional Studies;
A.) Hydroponic growth system
1.) plant roots lie on the surface of a trough, and nutrient solutions flow in a thin layer along the
trough over the roots and this system ensures that the roots receive an ample supply of oxygen
B.) Nutrient film growth system
2.) In this technique, plants are grown with their roots suspended in air while being sprayed continuously
with a nutrient solution, This approach provides easy manipulation of the gaseous environment around the root
C.) Aeronic growth system
3.) The technique of growing plants with their roots immersed in nutrient solution without soil and requires a large
volume of nutrient solution or frequent adjustment of the nutrient solution to prevent nutrient uptake by roots from
producing radical changes in nutrient concentrations and pH of the medium.
