Have you ever tried to plant flowers or vegetables in your yard, but couldn’t get it to grow? Maybe it is because of the type of soil you have in your yard. For example, when we lived in North Carolina, our yard was mostly made of sandy soil or 100% sand in some areas. In today’s episode, Braden and I are going to talk about the different types of soil that he learned about this week at school.
What is soil?
Soil is a mixture of humus, sediment, and dirt.
Humus is the organic parts of soil that come from decomposed animal remains.
