What kind of science is in soil? What is soil? So many questions…

Soil is a material composed of five ingredients — minerals, organic plant matter, living organisms, gas, and water. Are their soil scientists? Of course! 

What do soil scientists do? A soil scientist is a person who is qualified to evaluate and interpret soils and soil-related data for the purpose of understanding soil resources as they contribute to not only agricultural production, but as they affect environmental quality and as they are managed for protection of human health and the environment. WOW, soil scientists definitely play a key role in protecting our health and environment.

It seems to me that Soil is pretty easy to ignore. We might notice it when gardening or playing outdoors. But even when we forget about it, soil is always there, everywhere!

Most of what we see are mineral particles that we recognize as sand, silt, or clay. There is also plenty of water and air. But soil is also alive. It contains countless fungi and microbes. They help recycle dead and decaying matter by breaking down the remains of plants, animals, and other organisms. What if we could put on really cool goggles to see inside the soil, we would see an incredible microscopic world of fungi and bacteria? We need to talk about the bacteria in soil because they perform an incredible function. These bacteria are said to be symbiotic and are real helpers to the plants. These bacteria can convert nitrogen to ammonia, which the plants utilize for their development.

While soil science is fascinating, why are we talking about it now? Because World Soil Day is December 5, 2020. How do we celebrate World Soil Day, you might ask? The motto for World Soil Day is Keep soil alive and protect soil biodiversity! Plants nurture a whole world of creatures in the soil, that in return feed and protect the plants. This diverse community of living organisms keeps the soil healthy and fertile. This vast world constitutes soil biodiversity and determines the main biogeochemical processes that make life possible on Earth.

It turns out soil is a living resource, home to more than 25% of our planet’s biodiversity. Interestingly, up to 90% of living organisms live or spend part of their lifecycle in soils.

Next time you take a break and go outside, or maybe spend a few minutes in your backyard, reach down and take a good look at the soil. If you have a magnifying glass, bring it outside with you. When you look at the soil use your imagination and think about how many microorganisms there are in the soil, and how remarkably busy they all are!

One way to celebrate World Soil Day is to provide your soil with rich nutrients like those found in compost! Check out our at-home science experiment, Compost in a Cup! Grab your supplies & celebrate soil!
