Soil is just one of those things that for some is extremely dull and for others, like gardeners, is quite exciting. There are five things below about soil which could not be understood already.

Firstly, it’s a well-known fact amongst soil circles that about 25% of all the Earth’s soil is being destroyed by over-farming and poor agricultural techniques.

2. Whilst human-beings don’t tend to live in soil, other animal life does do and can reach the density of up to 10 tons per acre.

Thirdly, it is estimated that food is grown on about 10% of the world’s land in order to provide food for both human-beings and animals.

Four: The roots of plants can move through soil at the astonishing rate of half an inch a day in order to find moisture.

Fifthly, it is amazing to think that a simple earthworm is able to digest about 36 tons of soil before recycling it back into the soil layer making it rich and nutritious.

6. At least 1 million earthworms could possibly be found in just one acre of rich grass land – although counting them might be a problem.

7. Just 1 spadeful of soil could contain more species of living things than the Amazon rain forest contains in total above ground.

Eighth, as seeds, nuts and other things buried by wild creatures in the soil decompose, the soil benefits from the added material making it richer and more nutritious and improved.

Nineth, all the men women and children in the world wouldn’t add up to more than the number of clay particles that could be counted in one handful of clay.

Ten: Most soil samples would contain a breakdown of the following; 45% minerals, 25% air, 25% water and 5% organic matter.

Of course, there are many other fascinating facts about soil that you can learn. However, most people don’t have that much spare time to learn about soil, and so this list points out the most interesting.
