After looking at soil with grade 9 and convincing them that it's not just dirt and something that they got into trouble for coming home covered in, I'm not sure how I missed the fact that 2015 is the international year of soils.
The United nations food and agriculture organisation are trying promote awareness of a fact that many people have been saying for years. Take care of the soil and it will take care of you.
Healthy soils are good at storing water and filtering water, recycling essential nutrients, regulating atmospheric composition as well as being a habit for many organism. Pollutants, over farming and deforestation have all contributed to a decline in soil quality which has the potential to have an extreme impact on ecosystems across the globe.
I am extremely excited about a year dedicated to raising awareness about the importance of soil and to celebrate the resource that not only provides our food but so much more.
To kick off the year of soils, here are some interesting facts that you may not have been aware of.
- There are more microorganisms in a handful of soil than there are people on earth.
- It takes over 500 years to produce just an inch of top soil, the most productive layer.
- It greatly reduces flood risks by storing up to 9200 tonnes of water per acre.
- 10% of the world's carbon dioxide emissions are stored in soil.
