Upper School Soil Science
Our AP Environmental Science students recently worked this lab from their Earth Systems unit. The soil study lab involved comparing physical and chemical properties of three soil samples. We chose samples from a backyard lawn, an organic farm, and Harley’s microfarm.
The tests included timing how long it takes water to pass through a given amount of soil, and how much water the samples hold, plus looking at the chemical properties of the different soils (phosphorous, potassium, nitrogen, and pH level).
