Agronomy

NCSU/What Is Agronomy?

The school I go to is NCSU with the program Forage & Grassland Agronomy. Now if your wondering what agronomy is i'm here to tell you! Agronomy is the science of soil management and crop production. A real world problem is that the amount of soil has decreased 50% in the past years, so we need to step up and help!
What is Agronomy?

Weathering (Chemical vs Mechanical)

What Is The Difference?

Mechanical- The process of taking a big rock and making them smaller piece (Release of Pressure, Freezing and Thawing, Plant Root Growth, etc.) Chemical- The erosion or disintegration of rocks by a chemical reaction (Carbon Dioxide, Water, Acid Rain, etc.)

Soil

Soil Facts

Soil texture has an important role in nutrient management because it influences nutrient retention. Soil texture is related to sand, silt, or clay. Its based on it's relative proportions Soil composition is also important because its manages nutrients. A soil horizon is a layer generally parallel to the soil crust, whose physical characteristics differ from the layers above and beneath it soil usually have 4 horizons.

Soil Formation

What Affects The Rate Of Soil Formation?

Soil formation is affected by these 5 major factors- Time, Climate, Parent Material, Topography, and Organisms. All of these 5 major factors usually determine what kind of soil there will be.

Remote Sensing

What is Remote Sensing?

Remote Sensing is when a satellite or high flying aircraft is scanning the earth. It obtains information about objects or are from a distance. Remote sensors can be either passive or active. Passive sensors respond to external stimuli. The most common source of radiation detected by passive sensors is reflected sunlight.

Soil's Importance

Why is soil so important?

Soil is a vital part of the natural environment. It's just as important for plants, rocks, landforms, lochs, and rivers. Soil is important for plants because it holds the roots that provide support for plants and stores nutrients.

Common Misuses/Negative Consequences

What are common misuses in soil and their negavtive consequences?

A very common misuse of soil is if they put all that they're growing in one place! The negative consequence is that bacteria could be harmful to the other plants and start to kill them and they won't be able to grow.

Soil Stewardship/Advances

Soil Stewardship an its Advance

Soil erosion is a naturally occurring process that effects all land forms. In agriculture soil erosion refers to the wearing away of fields topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage.
