| Question | Answer |
|---|---|
| what is Active Organic Matter? | serves as a primary food for microbes to feed on |
| what is Alluvial transport? | movement of sediments by flowing water |
| what is Capillary Water? | soil particles held by surface forces in small or micro pores |
| what is Eolian Transport? | when wind moves and deposits sediments |
| What is leaching? | process of water drawing minerals to lower layers of soil |
| what are Aggregates? | formed when soil particles are bound together by clays and biologic glues secreted by plant and soil biology |
| what is Percolation | water moving vertically through the soil matrix |
| what is Porosity | total soil volume made up of pore space |
| what is Sheet Erosion | detachment of soil particles by rainfall or irrigation which are removed by flowing water as a sheet instead of rills or channels |
| what is Rill Erosion | results in small defined streams and occurs when rainfall or irrigation water does not soak into the soil, but flows across it |
| what is the water cycle? | the continuous process by which water moves across Earth’s surface, through the atmosphere, and under the ground |
| what is Evapotranspiration | occurs as plants uptake water from the soil through their roots into their leaf pores as part of transpiration |
| what is sublimation | happens when snow or ice change directly into water vapor which skips the process of melting back into a liquid first |
| what is a Nonpoint Source Pollution | any contamination which cannot be traced back to a specific point of supply |
| what is Flocculation | causes the formation of small masses or pieces |
| what is soil health? | the continued capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans |
| what is Carbon Sequestration | process of capt2uring and storing carbon dioxide |
| what is Autotrophic Organism | produce their own food |
| Heterotrophic Organism | receive their energy from consuming other organisms |
| Lignin | shapeless polymer linked to cellulose providing stiffness for woody plants |
| Detritus | dispersed pieces of rock material |
| Riparian Area | part of land along the sides of water bodies, typically known as flood plains or streambanks |
| Air Quality | measurement of how clean or polluted the ambient air is |
| Dust Suppression | implementation of materials to stop particles from being carried away by the wind |
| Windbreak Control | vegetative barriers, such as trees or scrubs, which aid in the management of air quality |
| Greenhouse Effect | when gases comprising the atmosphere absorb incoming radiation and act like the roof of a greenhouse |
| Nitrification | biological conversion of ammonia gas to nitrogen dioxide and then nitrate nitrogen |
| Ethanol | renewable fuel derived from plant materials |
| U.S. Air Quality Index, or AQI | air quality measurement; measuring from 0 to 500°F (-18 to 260°C) with 0 being least likely to be harmful and 500 being the most |
| Emission Plumes | pollutants in the structure of smoke or vapor which is discharged into the air |
| Cropping Systems | crop, crop sequence and management technique used on an agricultural field during a certain time period |
| irrigation | artifically applying water to soil to help plant growth. |
