Soils are a mixture of the broken remains of rocks and decayed organic matter in a given area; soils provide the nutrients that sustain plant growth. The difference between the soil of the Amazon and soil found in more temperate climates is striking. Students will study plant growth in soils with different nutrients and physical compositions. By examining data, students will come to understand the effects of nutrient depletion in the Amazon and the impact of tree and plant removal from Amazon soils. Students will be able to describe slash-and-burn agriculture and its impact on the environment.
