Come Be An Agronomist
North Carolina State University's Agronomy Department
Hi I'm Ryann, I am an employee at North Carolina State University's Agronomy Department. Agronomy is where they grow food then they study the food that was grown in the soil. Some people in the world like Africa they don't know when there next meal will be or how their water is muddy.
chemical and mechanical changes
Weathering has a big impact of chemical and mechanical changes.
Chemical:
water
oxygen
carbon dioxide
living organisms
acid rain
Mechanical:
release of pressure
freezing and thawing
animal actions
plant root growth
abrasion
Soil Facts
Soil is essential for food and water. There are many types of soil there is gravel, sand, silt and clay. The textures are sandy, silty and clay. The composition of loam is 25% air, silt is 18%, water is 25%, organic matter 5% and clay 9%
Soil Formation
soil is made form layers of the horizon. We can find humas (dead plants and animals), rock, organic and inorganic, insects, air and water to make soil. Also you want a warm and raining climate.
Remote sensing
When there is an earthquake they use a satellite to see how the earthquake started. After if they still cant figure out how it happened they would use a thing called remote sensing to sense if it happened underground where they couldn't see.
Importance of soil
If there wasn't soil today we wouldn't be alive. If there wasn't soil today we would have no food. We need trees to breathe and if thee wasn't any soil we wouldn't be able to breathe.
Misuses of soils
Some misuses of soil is farming if there is a big drought and you have turned your soil and a day is really windy you soil could just go away like dust. Another is littering we could help by picking up the trash.
The fields of argonomony
When your in the fields of agronomy you will be studying the soil and the food you grow. You will try to find better ways to make the soil or food better like putting them in shoes or the ground and see which one grows better.
