Title: Why would a plant wilt if excess chemical fertilizers were applied to it? Post by: smmiller223 on Mar 4, 2013 Does it affect the water uptake in the xylem? Please try to explain in biological terms :)
Title: Why would a plant wilt if excess chemical fertilizers were applied to it? Post by: bugaian on Mar 4, 2013 Fertilizers are composed of a number of chemical salts. Excessively high soluble salts hurt garden plants by causing root burn. The burning reduces the ability of roots to absorb water and nutrients. Roots of properly fertilized plants are able to carry out these essential functions without problem, but it's a different story with over fertilized plants. In fact, instead of being able to pick up water, water may actually flow out of the roots of these plants.
