This in contains many types of single celled

This experiment is designed to
observe how common human trash can be used to increase the growth rates of
plants. Several natural materials found within certain households can be used
to help the environment by providing the soil with a boost of nutrients via
decomposition that plants absorb through their roots system, aiding in growth (“Decomposition
and Decay,” n.d.). The soil that plants grow in contains many types of single
celled fungi and bacteria that aid in decomposition (Kowalski, 2016). Several
natural fertilizers added into compost piles to help create a nutrient rich
soil include: banana peels, coffee grounds, kelp, egg shells, and other fruits
and vegetables (“Everything You Need to Know About Organic Fertilizers,” 2017).
However, each organic material provides the plants with different amounts and
types of nutrients that can have an effect on the growth, strength, or
appearance of the plant. For example, banana peels provide the soil with a
large amount of Potassium, Nitrogen, and Calcium; coffee grounds add mostly nitrogen;
tomatoes provide potassium,
magnesium, and phosphorus; and egg shells provide calcium, potassium, and
phosphorus (Ahsan, 2014). Meanwhile, kelp provides
the soil with high amounts of nitrogen, phosphorus, and potassium (Grant,
2016). Furthermore, many plants thrive in soils that are rich with nitrogen,
phosphorus, and potassium as each element has their own effect on the
development and health of the plant. Nitrogen helps the plant form green
leaves, phosphorus is used in the development of roots and flowers, and
potassium helps the plant become more resistant to diseases (Sundblad, n.d.).
Typically, many of these natural fertilizers are used together, but this
experiment will test how each fertilizer affects the plant by itself.


While doing this lab, there are
environmental and safety issues that need to be taken into consideration. One
environmental issue that may result from the lab is the issue with wasting
water. This issue is mainly prevalent in California. Despite being considered
out of the drought, there are still water conservation laws in place to
maintain to prevent the state from entering another drought. This lab will use
about 18000 mL of water in total, excluding the water used to clean the shovel
used to for placing soil in the cups. Another environmental issue is the amount
of electricity wasted during the lab, as it required a lamp plugged in and
turned for 28 days. The environment issue is due to a waste of electricity. This
lab uses a constant stream of electricity for 10 hours for a full 28 days,
which is an extreme amount of electricity being used for this lab. One safety
issue is a risk of being electrocuted during the lab, as the lamps used in the
lab will need electricity. If any water were to accidentally splash onto or get
into the electrical socket, it could start a fire or electrocute someone. Another
safety issue also has to do with the lamps. The light bulb can become very hot
to the point where it could cause minor burns if accidentally touched. A third
possible safety issue is cutting oneself with the knife used to cut up to
organic material into smaller, easier to decompose chunks. The safety issue
arises from human error in which simply not paying attention or having fingers
too close to the knife may result in cuts/injuries. There were no ethical
considerations as the test subjects were plants, which are organisms that
cannot endure physical or mental pain. There was also no unauthorized genetic
modification of the lima beans during the experiment.


This experiment would show how
humans can help the process of decomposition by separating their trash by
organic and inorganic, as the soil can decompose the organic material faster,
thus creating the nutrients the plants need to grow. This experiment would
allow for an example of how specific types of compost affects different aspects
of a plant, and how farmers can use the results to determine the type of
natural fertilizers they would like to use to stimulate the growth of their crops.
This would also allow farmers with poor soiled land to rejuvenate their land
and open it up to the possibility of resorting life to it once more (Ahsan,
2014). This is also applicable to cities that heavily rely on farming as a
source of income, in which knowing which type of compost with different amounts
of specific organic material would be best for their specific crop will aid in
maximizing their crop production or time it takes for the crops to grow.
