Greetings, Emmet here and I have something incredible to show you – soil!
Mmm. Soil is the thin layer of lovely mucky stuff that covers the land.
It's vital to all living things.
Oh, lovely. It's made from particles of rocks and humus which is decaying bits of plants and animals broken down by microorganisms and this is all mixed together by worms and bugs over many years.
Hello there!
Now, different soils have different properties.
Sandy soils have large particles.
Water drains through them easily making them dry.
But clay soils… They have much smaller particles and get muddy when wet.
Apparently people pay good money for this!
Soil is a mixture of tiny particles of rock, dead plants and animals, air and water. Different soils have different properties depending on their composition.
- Sandy soil is pale coloured and has large particles. These create lots of small air gaps. Water drains through them easily so it usually feels dry.
- Clay soil is usually sticky and has small particles. They contain very few air gaps and water does not drain through it easily.
- Chalky soil is a light brown soil. Water drains through it quickly.
- Peat does not contain any rock particles. It's made from very old decayed plants and is dark, crumbly and rich in nutrients.
