Different Types of Soil

Hello Boys & Girls,


We will be looking at the different types of soil in class this week and getting a clear understanding of the composition of soils, the types of soils, and the relationship between soils and other living things. In order to have healthy plants the soil needs to have many nutrients! 

HUMUS

A dark-brown or black organic substance made up of decayed plant or animal matter.

CLAY


Soil is formed from very fine particles, such as silicates of aluminum, iron and magnesium. Clay soil prevents the flow of water, meaning it absorbs water slowly and then stores it for a long time. 


SAND SOIL 

Sandy soil has large particles that drain quickly but is unable to hold nutrients properly.
