Impact of Fertilizer on Plant Growth
Plants are essential cogs in the machine of the environment. All life forms on earth rely on their existence. Plant growth has been studied and manipulated often in history. Mankind has tried to accelerate the growth of plants like fruits and vegetables through various means including irrigation. (LaLiberte, 2014) Fertilizers of various types have been used as an option used for many years but it is essential to observe for oneself whether fertilizers actually have an impact on the growth of plants. By using fertilizers, if the plant growth can be stimulated then it can be used for many other purposes and it really can be relied upon for accelerating plant growth at a mainstream level as long as it doesn’t alter the final product in a way that it becomes harmful. (Mózner, Tabi, & Csutora, 2014) The current experiment utilizes the radish plant and even if it can be considered as a root plant, its growth can be efficiently tracked without digging out the plant as there is abundant growth noticed above ground. (GEEKGARDENER, 2010)
1) The experiment can also include the factor of whether increasing or decreasing the amount of fertilizer has an impact on plant growth in order to derive the perfect amount to be used for plants.
2) The experiment can be enhanced by including various brands of fertilizers available in the market to find which fertilizer works best for plants.
3) The most essential follow-up to this experiment would be to test the effect of fertilizers on different type plants which are extensively used or consumed to find if fertilizers are effective on all types of plants.
If I add fertilizer to one of the growing plants than I will see an accelerated growth in the plant with the fertilizer.
My parents and relatives encouraged me to follow through with the experiment and helped me with the resources and my classmates were excited to know how the experiment 3was going to be executed. My teachers were fully supportive about the idea and helped at their full capacity.
Place 2 radish seeds in each of the plastic pots filled with soil to ensure that at least one of them will grow. Label the pots to indicate which plant has fertilizers applied in them. Pour water throughout the course of the experiment at a regular interval of 2 days. Apply fertilizer after every 15 days as excessive fertilizer would hamper plant growth. Record plant growth
• Concentration of fertilizer
• Presence of fertilizer
• Amount of water
• Amount of seeds
Growth of the radish plant
The control group includes some of my trustworthy classmates whom I have assigned the responsibility of checking on the plant growth and noting down the changes if because of a certain situation I am not able to do it myself.
Effectiveness of fertilizer
The data collected will be noted down initially in a notebook after observing the length of plants and then the data will be documented in an excel spreadsheet.
1) Both the plants will grow at the same speed rendering the fertilizer ineffective.
2) The plant without the fertilizer will grow faster than the plant without the fertilizer.
3) The plant with the fertilizer will grow faster than the one without the fertilizer.
Growth without fertilizer
Time Frame 1st week 2nd week 3rd week 4th week
Length of Plant (cms) 0 5.5 9 12
Growth with fertilizer
Time Frame 1st week 2nd week 3rd week 4th week
Length of Plant (cms) 0 7 13.5 15
After analyzing the data it has been observed that both the plants show growth but the one with fertilizer has grown faster.
The results clearly indicate that the plant’s growth rate has been positively affected by fertilizers.
The hypothesis was sufficiently supported through the course of the experiment.
After analyzing the findings of the experiment it can be derived that plants grow better when the soil is mixed with a normal amount of fertilizer. If the plant growth can be stimulated with the help of fertilizer then it should be extensively used for irrigation and the first-hand observation has cemented the speculation that fertilizers have a positive impact on the growth of plants.
The strength of the experiment was that its execution required apparatus which was readily available without applying much effort and once the planting was done, there was no further endeavor required other than measurement.
The difficulties were very minute and only in the initial stage of digging and carefully planting the seeds. The research could be improved if the soil fertility had been analyzed for better results.
