In agriculture, the use of soil testing and soil maps are important in determining the nutrients available or finding deficiencies. Soil testing can also be useful to backyard gardeners and homeowners, to allow the successful growth of plants. In this project, students will work in groups to test a local soil sample in the following areas: pH, Nitrogen, Phosphorus, and Potassium and create a soil map to present to the class.
Lesson #1- Students will become familiar with what a soil map is utilizing the USDA soil survey website.
Lesson #2- Students will test a local soil sample for pH, Nitrogen, Phosphorus, and Potassium.
Lesson #3- Students will utilize soil testing results to create a soil map.
Lesson #4- For the final lesson, students will share their soil map with the class and look at the bigger picture of the impact of the soil type on the community.
