Has anyone ever wondered about how fast things decay? Well I have started a project to find out. I have decided to take 4 pots and fill them with dirt. I will then bury a raw potato cube at different depths and check on the potato every 2-3 weeks. Photographs will be taken and compared. This topic will most likely help farmers who grow certain raw crops. First, I will talk about my independent variable. It …showed first 75 words of 331 total…

The decomposition of crop residue and transformation of organic nitrogen (N) into ammonium (NH4) and nitrate (NO3) forms (a.k.a. N mineralization) provide sources of plant available including potato. The rate of the decomposition of a raw potato is my topic and science fair idea. To summarize this entire review of literature, the raw potato decay rate will be increased with the depth of the raw potato.
