Humus Lab Report

In the humus lab were were trying to find out if hydrogen peroxide would cause a reaction and show us the amount of humus in the soil by putting gas into a graduated cylinder with water to make the water level lower therefore showing us how much humus the material being tested contained. It showed that the sand was lacking humus but the mushroom compost was the most rich in humus. My hypothesis was correct because I predicted that the mushroom compost would produce the greatest amount of humus out of the four samples with sand being the least since it is just ground up rocks. In the experiment we determined that compost is the most nutritionist soil for humus to grow and thrive in with shaded soil next because the shade lets it dry slower
