Experiment with soil erosion

What is soil erosion? Erosion is a natural process where soil particles and nutrients are taken away by water and wind from, for example, a grain field and deposited into a water body, like a lake, or a river.

So, particles and nutrients are needed on fields, so that plants can grow better. In small amounts they’re also help for water-plants and animals, but in large amounts they can create problems.

In this do-it-yourself experiment, you will compare 2 types of soils (grassland and garden soil) and observe how the quality of the soil and the presence of a thick root map can influence how resistant the soil is to erosion, and how many nutrients are retained in the soil when exposed to rain and wind.
