Pre-Lab Greenhouse Experiment
The Soil Analysis Lab will cover one of the three soil quality indicators. (The three indicators are physical, chemical and biological). This lab will evaluate the chemical indicators: pH, nitrates, phosphates and phosphorus. We will look at soil composition (the percentage of silt, clay and sand).
In class today, we will review the procedures for the experiment and run through one of the tests. Please be sure to dress to play in the dirt on Wednesday!
