Earth Learning Idea (ELI)


Sandy soils allow water through easily and clay soils do not. Garderners usually prefer loam soils. For a farmer or gardener, it is important to know the soil type so that it can be managed properly and crop production increased. This activity can be used in any lesson about the environment, rocks and landscape, agriculture, gardening or investigations out of doors.
