Decomposition of Apples

I have always been interested in the environment and this experiment intrigued me. I was curious about which environment would allow the apple to decompose after you throw it out your car window or litter in the park. The soil used in the experiment was found in my back yard. According to my research soil is made up mostly of weathered rock, air, water, and organic volume. McLean County is known to have the richest soil in the world. Also, the researcher can find bacteria in soil. In order for anything to decompose you need to have organic matter, moisture, oxygen, and bacteria. Soil has all four of these components therefore making it an ideal location for an apple to decompose. Mud is a form of soil that is saturated with water. However just because mud also has moisture, bacteria, and organic matter, mud doesn’t have oxygen. By not having oxygen the apple will saturate itself with water and will not be able to breakdown the material by bacteria. Sand is a very dry environment and the apple will decompose over a time period but will not be as rapid. Sand is mostly made of material grains. According to the University of Illinois, “a garden with sandy soil has very little water and nutrient retention,” this will cause the decomposition to occur very slowly. By putting air holes in the top of the container lid it is allowing oxygen to circulate through all of the environments. After the apple has fully decomposed in the soil compost is made. The Webster Dictionary’s definition of compost is, “a mixture that consists largely of decayed organic matter and is used for fertilizing and conditioning land.” Compost is improves the soils structure and helps keep in air, nutrients, and moisture for the plants growing in the compost. Once a pile has decomposed and turned into compost “the volume of the finished compost has been reduced because of the biochemical breakdown and
