Soil is all around us, and a lot of people just think it is there for growing plants and vegetables. But there is a lot more to soil than you think.
1. 50 Earthworms per square foot of soil
There could be up to 50 earthworms per square foot of soil. Earthworms and other critters enrich the topsoil by feeding on the organic matter and converting it to nutrients.
2. Antibiotics are made from micro-organisms from soil
Almost all the antibiotics we take for infections or other health reasons were obtained from soil micro-organisms.
3. Around 10% of the world’s CO2 Emissions are stored in soil
Emissions are stored in soil Soil stores our carbon as soil organic matter. It plays a key role in the carbon cycle as well as helping with climate change.
4. 500 years to create 1 inch of topsoil
You probably didn't know this, but it can take more than 500 years to create one inch of topsoil.
5. Lots of micro-organisms in a handful of soil!
There are more micro-organisms in a handful of soil than there are people on earth! Most of them haven't been identified yet.
6. Soil is a living system
It contains millions of organisms, such as bacteria and fungi, that help break down organic matter and contribute to the overall health of the soil.
7. Soil is a natural water filter
Soil plays a big part when it comes to water. Soil acts as a filter for underground water, filtering out pollutants. It can also hold up to 9200 tonnes of water per acre, which reduces flood risks.
8. Soil provides all the nutrients for successful plant growth
Soil provides all the nutrients needed for successful plant growth. It consists of 45% minerals, which vary depending on different soil types, 25% water, 25% air, and 5% organic matter. The composition of soil particles and its cation exchange capacity influence its fertility and soil erosion.
9. Soil is home to many species
Soil is home to a quarter of all known species on earth. It forms a complex ecosystem that supports various plants and animals.
10. Soil has 6 layers
Healthy soil has 6 layers called Horizons O, A, E, B, C, and R. Horizon O represents the topsoil, which is rich in organic material and vital for sustaining plant growth. Horizon R is the bedrock, which is the deepest layer.
Summary
Understanding the importance of soil is crucial for sustainable agriculture, food security, improving soil health, and maintaining soil fertility. Managing soil erosion through appropriate soil management practices, such as adding plant residues and organic material, can improve soil quality and enhance crop production. Additionally, maintaining a balance of soil organisms and promoting soil carbon sequestration contributes to ecosystem services and environmental sustainability. So, next time you dig your hands into the soil, remember the hidden world beneath your feet and the vital role good soil plays in supporting life on Earth.
