Describe nutrient exchanges in a soil. Relate and describe the Cation Exchange Capacity in a soil.

Select the correct answer regarding cation exchange and plant mineral nutrition     cation exchange is necessary because negatively charged ions are stuck to inorganic particles of soil     cations are likely to leech out of the soil if there are drainage problems or flooding     hydrogen ions freely diffuse out of plant roots into soil     cation exchange works because plants substitute a strongly charged cation (H+) for required minerals     waste products from cellular respiration provide an energetically free (no ATP needed) mechanism to exchange cations
