Salt is applied to tennis lawns to kill weeds. How does salting tennis lawns help in killing weeds without affecting the grass?
Answers (1)
Salt increases the concentration of the soil, causing the water in the roots to move out through osmosis in order to balance the concentration leading to excessive water loss. While it can reduce weeds, the application of salt can also be harmful and damage plants and instead should be applied as a solution and not a direct application of salt.
