This 2 day lesson includes a review on the twelve soil orders found on our planet and common soil testing procedures. Students will learn how to perform a soil ribbon test to determine the soil type, and measure the water holding capacity of a soil sample.
This final lesson in a sequence of lessons about tillage, agricultural practices and soil chemistry will combine all of the unit's content into a cohesive presentation that will prepare them for their summative course assessment. Course project soil data will serve as the foundation for the presentation.
