Salt Effect on Grass Growth Experiment

This practical assignment explores the effect of salt on grass growth through a controlled experiment. The experiment uses a two-level factorial design to compare grass growth in areas with and without added salt. The results indicate that salt inhibits grass growth, likely due to osmosis drawing water out of the grass roots. The assignment also suggests further investigations, such as varying salt levels and testing without snow, to gain a more comprehensive understanding of the phenomenon. The provided references support the experimental design and the scientific principles involved.

EFFECT OF SALT ON THE GROWTH OF GRASS
1.0. Introduction
During the winter season, you spread salt day by day on your driveway to liquefy the snow.
In the springtime, when the garden starts to develop, you see that there is no grass developing
for around three inches from the garage. Besides, the grass is by all accounts developing all
the more gradually up to around 1 foot from the driveway. It indicates that the salt so
introduced during winter season might reduce the growth of grass.
2.0. Hypothesis
At the point when the snow softens or liquefies with the salt on top of it, it assimilates water
and salt into the ground harming or crushing the grass roots therefore, the grass cannot grow
further. If the hypothesis is true pertaining to the salt-water absorption, the grass cannot grow.
3.0. Controlled Experimental Method
In a yard with snow, over grass, set up an experiment utilizing a two level factorial design
(Jaynes et al., 2013). Ensure to separate the grass sheets for at least 3-5 feet so that the growth
of the grass does not influence each other. Two of the experiments are meant to study the
effect of salt, so include known amount of salt (E.g., 100 gm of salt/feet2) and the other two
serves for control (no salt). The two boxes with salt liquefy even more rapidly that the two
without, for them you would need to sit tight for a warm day. Measure the height of grass on
each day for all the grass for at least 15 days. To ensure the consistency of salt in the field,
the salt level should be tested and it would be desired to have above 4.0 mmhos/cm. The
regular soil should show less than 4.0 mmhos/cm.
4.0. Results
The outcomes being that the two boxes with salt in them have 4.0 mmhos/cm, inhibits the
growth of the grass and the two boxes without salt in them allow the growth of the grass. This
could be probably due to damage of grass cells creating a high concentration of salts in the
environment. The high concentration of salts probably pulling the solvent molecules from the
grass roots to out by osmosis making the grass to die (Plant and Water Relationship, n.d).

Therefore, the growth of grass from the salt field is less significantly less compared to the
field without salt.
5.0. Conclusions
I certainly support the outcomes gave from this analysis making my speculation correct and
valid. I do however trust that this investigation could do with an extensive investigation. For
example, doing a few trials with changing levels of salt in each to perceive how much every
sum influenced the development of the grass. And furthermore doing ones without snow to
ensure the snow isn't bringing on additional unfriendly impacts, it's impossible that snow
would make to a greater degree an issue than salt however until tried the response to that
specific question is obscure.
