Investigating the Effect of Different Organic Substances in Changing Soil pH in the Environment

Overview

Objectives/Goals The objective of this project is to investigate how pH levels of our Central Valley's orange orchard soil is affected when different organic substances have been added to it. Methods/Materials pH meter, orange orchard soil, one 16oz. Cup, fifty 5oz. Dixie cups, 4 different organic materials, one container capable of holding 15lbs., food scale, 3 pound containers Results I conducted multiple trials to ensure a preside average of the effect the organic materials had on the orange orchard soil. At the end of my expirement I realized that my organic materials have turned into organic matter. What I mean is at first my soil was affected by the new additives. As time went on, however, the levels began to increase back toward the neutral area. What this means is as my expirement length increased my organic materials be came organic substances. Conclusions/Discussion When my project was complete I had concluded my hypothesis had been incorrect. However, at the beginning of my expirement it had been correct, but as time went on the results changed. I had thought that my project would have a result of the soil becoming more acidic. This did happen to the soil at the beginning of my project, but soon the levels began to become increasingly alkaline. This is because the organic materials began to decompose and soon became organic matter thus no longer affecting the pH levels of the soil.
