The observation or the option that is choose is part A - Might grass growth be inhibited by salt Introduction Salt is the one that usually raises the level of solute level of the soil around the root of the plants or grass. Hence the higher solute level outside or near the plant root will in turn sucks the water of the plant by the osmotic gradient (1) and thus the salts in high levels will inhibit the growth of the plants and may even leads to the death of the plants or grass. In general salt will kill most types of the grass. Thus the growth of the grass depends on the amount of the salt, type of salt, water level and thus the type pf grass. Some salts are beneficial for the growth of the grass but too much of any thing will kills. Table salt is commonly known as sodium chloride can be effectively used as a weed controller. Thus the salt draws out the water from the cells of weeds that effectively kill the grass. If you place a spoonful of salt in the roots of the grass it will kill them with in three days
