Chicken Poop As Fertilizer

The purpose of this experiment was to test different fertilizers and their effect on the height of zinnias. To carry out the experiment nine plants were planted in sheep fertilizer, nine in chicken fertilizer, nine in processed fertilizer, and nine in plain potting soil. The plants were watered daily with 12 ml of water. A heat lamp was placed over them to act as the sun. It was turned on in the daytime, and it was turned off at night. The height of each plant was measured in mm daily.

After completing the experiment, it was found that the chicken fertilizer was the most effective. The average height for the nine plants, after 18 days, in chicken fertilizer was 52.67mm. Processed fertilizer was the second most effective. After 18 days in processed fertilizer the average height of the plants was 47.13mm. Plants in potting soil, after 18 days, had an average height of 43mm. The average height, after 18 days, for all nine plants in sheep fertilizer was 38mm.

There are two simple ways to explain why this was the case. The first reason is zinnias prefer soil that is neutral to acidic. Chicken manure is acidic, so when mixed with potting soil, to form a fertilizer, it perfectly meets the requirements of zinnias.

The second reason is when the sheep and chicken manure were added to the soil the sheep was expected to have an advantage by making it more porous. However, when potting soil was added to sheep manure it created a more dense soil. Therefore both the chicken and sheep fertilizer were equally disadvantaged.

These two reasons explain why chicken fertilizer is the most effective on plant growth.
