Scientific Inquiry




Duringthe winter, snow and ice is a typical thing due to low temperatures.The population’s demand of having swift driveways leads tocontinued use of salt to melt down the snow. This allows safe travelfor motorists and pedestrians (Carrow &amp Duncan, 2007). Theprocess of applying salt has to be repeated continuously to keep theroadway from re-freezing again. It is through a chemical reactionthat the snow melts by the salt application process. However, thereare effects that come with this process. For instance, when themelted snow (water) is absorbed into the ground, it can be harmful tothe grass roots, therefore, inhibiting the grass growth (Carrow etal., 2007).


Differentmechanisms like aerosol spray by fast moving traffic or winds blowingalong wet salted roads can disperse the salt. This salt accumulatesin the soil along the driveway and sidewalks. When the roots ofplants take up salt, the salt can accumulate in the plant. This saltcan influence salt injury and damage to the lawn as well.Consequently, in the springtime, when the growth of lawn begins, aperson will observe that there is no lawn growing for about threeinches from the sidewalk or driveway. Moreover, the grass appears tobe growing slower up to about one foot from the sidewalk or driveway(Central Soil Salinity Research Institute, 2004).

Afterspreading salt into the snowy driveway, a number of reactions occurresulting to the melting of snow. Salt water has a lower freezingpoint than fresh or non-salty water. This is due to the ions in saltwater. Therefore, when salt is applied to snow or ice, the snow orice will melt unless it is cold, like possibly below zero Fahrenheit.After this process, a solution of salt and water, which in this caseis contaminated water, will be absorbed into the ground.Consequently, groundwater contamination occurs (Carrow et al., 2007).

Ifsnowmelt or rain does not dilute salt that was poured on drivewaysand sidewalks, the soil turn out to be very salty and can injureplants. Moreover, if salt plants may also have deposits of salt onleaves and twigs. This can lead to dehydration of the plants causingit to turn brown as the salt draws moisture from the plant (Carrow etal., 2007). Additionally, the severity of the injury increases withthe amount of salt used and the speed of traffic. As well, grass onthe side of where the wind blows to (downwind) show more damage thanthe grass that is upwind. This is an indication that wind candisperse salts resulting to plant damage (Central Soil SalinityResearch Institute, 2004).

ControlledExperimental Method

Toprove that pouring salt during winter may affect the growth of grassduring springtime, a person can collect soil samples during earlyspring. This should be done before the rain dilutes the amount ofsalt in the soil. The soil samples can be taken into the soil andplant analysis lab for further analysis. Soil test can confirm saltinjury diagnosis. The results will show if the salt quantity isharmful

Weproposed to test this theory by building test plots of 21 grassassortments chosen for tolerance to salt in the high salt zone. Thegrass variety trial was joined with a test of two potential low costsoil changes: yard waste manure and biosolids. We likewise proposedto screen salt statement in excess of two winters at six destinationsto figure out the amount salt the grass was being exposed to, and towhat extent the salt endured in the root zone. Steadiness is criticalbecause the grass is more delicate to salt harm when it isenergetically developing (April-October) than throughout the wintermonths. In the meantime, we proposed to review the vegetation onsettled, cut roadsides to figure out which plant species were gettingby, as these may be great applicants for consideration in an adjustedseed blend (Carrow &amp Duncan2007).


Wefound that salt tolerant grasses demonstrated no change in survivalover the grass assortments effectively being used, despite the factthat the salt tolerant grasses had indicated better survival innursery salt screening trials. This proposed that the salt was notthe essential driver of vegetation frustration the finding that thesalt did not persevere in the root region at levels high enough tocause plant harm past early April further supported this theory. Soilchange, nevertheless, had a sensational impact on turf grasssurvival. Enduring vegetation blanket on plots changed with biosolidsstayed over half all through the two-year study, and past (Carrow &ampDuncan2007).


Inconclusion, salt does affect grass growth and most other types ofvegetation. Sodium in small amounts is necessary for plant growth.Usually, there is some acceptable quantity of salt in the soilalready. Nevertheless, exposing grass to excess high concentrationsalt quantities will probably kill the grass since the cells of grasshave a certain quantity of water and other dissolved substances. Whenput in high salt concentration conditions, there is a universal rulethat the water will move between the inside and the outside of thecell wall to make the quantity of dissolved substances equal.Therefore, the plant`s cell will collapse due to the osmosis process.
