2017            Sandand Tritium Aestivum (Wheatgrass): ADemonstration of the Effect of Sand on Plant Growth   Abstract            This report discusses the impact ofsand on wheatgrass plant development. We hypothesized that the spread of waterwill help the plant grow with sand added into the soil mixture for theexperimental wheatgrass plant. Soils containing sand mixtures evenly distributedare more efficient and effective in producing a better growth environment forplants versus soils that do not. Studies demonstrates that a sandy soil is anatural characteristic that is essential to retaining water and supplements forplants.

Therefore, when two similar plants are grown in comparison, a change insoil will highly influence growth. Introduction            The goal of this experiment is toobserve and analyze whether the addition of sand will increase absorbency, thusproviding better flow into the soil system. The main dependent variable isgrowth, development, and health of the plant. Soil type, thusly can adjust aplant’s impact on soil through consequences for plant production (Hancock,Bradley, Giardina, & Pregitzer, 2008). Sand is known to have some silt andorganic matter which is best for growing plants. Sandy soil is a poor averagefor water storing, therefore, watering plants all the more frequently and atshorter intervals will go far in keeping the soil saturated (Leineriza, 2011). Overall,a soil mixture of sand and soil should promote an overall effective growth environmentcompared to a soil without sand.

Wheatgrass – a typical plant presented toeither a sandy soil or consistent soil will be developed and analyzed.Therefore, one sample will be wheatgrass grown in only organic soil and theexperimental wheatgrass will be grown in organic soil and sand. Materials and MethodsA plant pot was utilized to run theessential theory. Two separate blends, the control and the experiment were setin the plant pot for investigation.

Twenty wheat grass seeds, were planted inthe mixture of half sand and half soil was added to the experimental plant pot,and the control group which was filled with just soil. The two gatherings wereroutinely watered 3 times each week with 1/4 cup of water, and left at a windowsill, accepting a similar level of daylight, with a similar room temperature.The length of the trial went on for around 2 weeks. Once the analysis wasfinished, plants from both the control and the experimental were cut from thebase of the soil, and lengths were measured by utilizing a standard 12-inchruler. Scaling of plant lengths was in centimeters. Graphical examinations,along with a t-test was kept running with a specific end goal to set up anaccord of the experiments success.

Furthermore, a null hypothesis will beconceivable if an expansion of sand neglects to have any effect on development. Results            Both plants displayed a decentamount of growth over the two weeks that the plants were watered. The controlgroup wheat grass plant had a mean length measured at 22.1 cm, while the experimentalgroup had a mean length measured at 26.9 cm.

When the t-test was conducted, thep-value was 0.0105. Figure 1 shows the evaluation of the lengths of both thecontrol and experimental plants under a box and whiskers plot. This means thatour data has a statistically significant difference and there was no differencebetween the means of our data. Therefore, the null hypothesis where expansionof sand has no impact on development, is neglected, as there is a normal plantlength contrast of 4.

8 cm between the control and experimental.                    Figure1 shows the differenceof growth values between the control group (without sand) and the experimentalgroup (with sand). A box and whiskers plot was used to show the range of plantlengths relative to both parties. The figure shows significantly larger plantlengths from the pot plant including sand versus the pot plant without sand. At-test value of 0.0105 shows a significant relationship. Discussion            Our results caused us to reject ournull hypothesis and accepted our hypothesis. The t-test that was revealed showedthat there was a statistical significant difference in our data because the p-valuebeing 0.

0105. The experimental group demonstrates a significant connectionbetween the expansion of sand on a soil body to the development of a plant,when contrasted with a plant that did not get any sand and was entirely naturalsoil. Soil is a dynamic three-dimensional substance which emphasizes plantdevelopment by giving anchorage, oxygen, water, temperature adjustment andsupplements (Berg Stack 2016). We can say this because when measured the valuesof the lengths, it ended up being higher for the experimental plant than it didfor the control group. One question that has left me wondering is what wouldhave happened if we added more sand to the soil rather than doing an evendistribution of sand and soil for the experimental group, would our plant growjust the same or would the lengths of plant be taller or would it not grow atall? In the article, “Soil and WaterRelationships,” it states that permeability refers to the development ofair and water through the soil, which is essential since it influences thesupply of root-zone air, dampness, and supplements accessible for plant uptake.Therefore, since our plants sat on a window sill, it was exposed to a lot ofair which is most likely the reason why the roots ended up sprouting so tall,because the plants were getting sufficient nutrients.

Due to a hugerelationship in the t-test, the hypothesis that sandy soils create moreproficient development environments than soils without sand is fruitful.Literature CitedBall, J. (n.d.
