DSL 200 LABORATORY REPORT THREE DSL 200 Laboratory Report Three 1 DSL 200 LABORATORY REPORT THREE 2 Laboratory Report Introduction When referring to the way human activities can contaminate the soil, the options are many and very varied.It is essential to maintain a healthy soil in order to support agriculture as most of the products we eat are coming from the soil. Because of that is very important to be able to protect it in order to be able to raise plants and the first step we have to do is to understand what substance can contaminate it and what will be the effect. For today's laboratory, we are going to conduct an experiment regarding the ph level of the soil and determine how it is going to be changed when we add different substances. The ph value determines if a substance is acidic ( a value under 7 ), neutral ( a value that equals 7 ) or alkaline ( a value over 7). There are several signs which indicate that the soil is damaged and the following are just a few examples: the soil drainage is poor, many predatory insects, many weeds, dry and cracked areas and many water pools on the surface of it. Hypothesis For today's experiment, we are going to test the way a chosen liquid interacts with the ph of the soil. This simulates the effect of human activities and for that, we are going to use nontoxic common substances such as orange juice. At the end of the experiment, I expect to see a decrease in the ph value of the tested soil that will confirm that indeed human activity affects the soil. 3 DSL 200 LABORATORY REPORT THREE Methods The following materials are required in order to be able to conduct this experiment : 1 (one) soil sample , 1 (one ) clean spoon , 2 (two) small cups , ph paper ( known as ph strips), timer ( the one available on mobile devices can be used ), duct tape , 1 (one ) coffee filter. We are going to being the experiment by determining the ph value of orange juice. In order to do this, we will pour it into a cup and then use the ph strip to measure it. In order to do this, is is required to dip the ph strip into the liquid, wait a few seconds and then compare the obtained color with the color scale available on the packing.Once we obtained the value we are going to record it in the notebook.For the next step we are going to add orange juice together with the soil in the same glass and stir it vigorously and after that, we should let the sample sit for around 45 (forty-five) minutes. During this time we can prepare the runoff filtering container by adding the coffee filter on top of the empty cup and fixating it with the duct tape. After the 45 (forty-five ) minutes passed we should pour the component in the glass with the coffee filter and wait for it to fill the glass. Once it is done we can remove the duct tape. We should take a new ph strip, measure this time the ph value of the new substance and note it in the chat. Results Name of Substance Hypothesis Ph level Acid/Base/ Neutral Only Soil Neutral 7 Neutral Only Orange Juice Acid 4 Acid Orange Juice + Soil Acid 4 Acid Graphic 1: Chart featuring the substances used and their ph level DSL 200 LABORATORY REPORT THREE 4 Based on the given information we know that the ph of the soil we are using in this experiment is 7, which means it is a natural soil. After using the ph strips to test the orange juice we concluded it is an acid because it has a value of 4. After mixing the two components together we obtained a value of 4 on our ph scale which means that it is acid. This shows us that the orange juice influenced its value. Discussion Based on the completed chart, we can state the hypothesis we presented in the beginning of this laboratory report is correct and the substance we used changed the ph of the soil we tested. It shows us that using an acidic substance such as orange juice will change the neutral ph value to an acidic one which can seriously affect the health of the plant.There are myths stating that feeding the soil with orange juice might make it more fertile, but this experiment shows us that citrus juice might be just too acid for it. It would be interesting conducting an experiment where we test the way a plant reacts to only orange juice as the main source of nutrients in comparison with water and with orange juice diluted with water and mixed well. As a conclusion of today's experiment, we can say that human activities definitely interfere with the health of the soil and we should be more careful regarding what substances we use as it might have severe consequences on its fertility.

How Humans Affect Soil Chemistry
Introduction
There are many ways in which human activities alter the chemistry of the soil,
particularly the soil PH. The identification of how human beings interfere with the chemical
composition of the soil is essential. The soil is the source of human livelihood, and any
interference with its chemistry will have a significant adverse impact on human life (KabataPendias, A., & Mukherjee, A. B. 2007). This is because the soil is the backbone of agriculture
that is the primary source of all kinds of food consumed by human beings. The agricultural
activities such as crop cultivation and animal production all rely on the soil (Scudder, 1996). The
soil PH and fertility are the primary determinants of the health of the crops and vegetation cover.
Therefore, conservation of the soil PH and fertility should be a very critical part of human life.
This is because interference of the soil PH by human activities can have a severe negative impact
on the cultivation of the crops. Scientifically, almost all crops require a neutral PH (PH value of
7). The alteration of this PH to acidic (PH value below 7) or primary (PH value above 7) by
various human activities affect the growth of the plants (Kabata-Pendias, A., & Mukherjee, A. B.
2007).
Literature Review
This experiment is meant to validate the fact that human activities have a significant
impact on the chemical properties of the soils. These human activities affect the soil by
interfering by the natural constituents of the soil and PH. This is because of the addition of
several elements into the soils, which changes the chemical composition of the soil (KabataPendias, A., & Mukherjee, A. B. 2007). This experiment hypothesizes that human activities have
a significant impact on the soil PH. This is tested by determining the way a selected liquid
(common non-toxic substances such as orange juice) interacts with the soil and change interfere

with its PH. This indicates clearly the effect of human activities in the soil. The non-toxic
substance such as orange juice is expected to reduce the soil PH since it is acidic, thus,
confirming how human activity has an impact on the soil.
There is a scientific confirmation or prove that human activities have a significant impact
on the chemical properties of the soil. From the past archeological studies, identification of the
presence of phosphorous in the soil has been utilized as a prove occupation of human beings in
that study site. This mineral has been used by the archeologists as an indicator of the impact of
human activity on the soil. This is because human beings always discharge mineral substances
such as phosphorus into the soil. This scientific proof suggests that indeed human activities
affect the soil chemistry (Dauncey, 1952).
Experiment
The experiment was performed by determining the effect of orange juice on the PH of the
soil. The following materials were utilized in conducting this experiment: Sample of soil, a clean
spoon, small cups, PH paper, timer, duct tape, and a coffee filter. The PH value of orange juice
was first determined by pouring it into a cup and then measure its PH using the PH strip. The PH
strip was dipped into the orange juice, left for some seconds then its color compared with that
available on the packing. The obtained value was recorded in the notebook. The next step
involved the mixing of juice together with the soil in one glass, and the mixture stirred
vigorously and left undisturbed for 45 minutes. During this waiting period, the runoff filtering
container was prepared through the addition of the coffee filter on top of the empty cup &
fixating it with the duct tape. After 45 minutes have elapsed, the mixture was then poured into
the glass with the coffee filter and the duct tape removed after pouring. The new PH strip was

Graphic 1: Chart featuring the substances used and their ph level
Based on data obtained, we can conclude that soil has a neutral PH. On the other hand,
orange juice and a mixture of orange juice and soil are acidic since the PH value is four which is
less than 7. This indicates that the orange juice affected the PH value of the soil from being
neutral to acidic.
Conclusion
Based on the completed chart, the hypothesis presented at the start of this laboratory
report is appropriate, and the substance utilized changed the soil PH. This indicates that using an
acidic substance such as orange juice will change the neutral PH to be acidic, which can
seriously interfere with the growth of the plants. In summary, human activities interfere with the
chemical properties of the soil....
