As part of a unit on soil, a chemistry/biology teacher at a private school requested the CEA for ANR to do a presentation on the most important issues affecting soils in Kentucky. The agent presented a lesson on compaction, erosion, soil structure, and nutrient content. The lesson also included content on soil types and parent material. It concluded with a visit to the school's raised plant beds and discussion on root horizons, weed identification, and weed types. None of the 13 students, who ranged from 7th to 12th grades, reported a background in agriculture, but after the lesson all the participants stated that they had increased their understanding of the characteristics of soil and their ramifications for production of food and fiber.
