- Conservation Technical Assistance (CTA)
- CTA has been the central activity of the Natural Resources Conservation Service since it was established in 1936. NRCS field staff help landowners and farm operators plan and implement soil and water conservation and water quality practices. The most common use of this program in recent years has been preparing and updating conservation compliance plans. In FY1993, CTA assisted 1.2 million farmers and serviced 62 million acres.
- Conservation Tillage
- Any tillage and planting system that leaves at least 30% of the soil surface covered by residue after planting. Conservation tillage maintains a ground cover with less soil disturbance than traditional cultivation, thereby reducing soil loss and energy use while maintaining crop yields and quality. Conservation tillage techniques include minimum tillage, mulch tillage, ridge tillage, and no-till.
- Constant Returns To Scale
- When all inputs are increased by a certain proportion, output increases by the same proportion.
- Consumer Price Index (CPI)
- A measure of the average amount (price) paid for a market basket of goods and services by a typical U.S. consumer in comparison to the average paid for the same basket in an earlier base year.
- Consumer Protection Legislation
- Laws aimed at protecting consumers, for instance by assuring that consumers have more complete information about items they are considering buying
- Consumer Sovereignty
- The principle that holds that each individual is the best judge of what makes him better off.
- Consumer Surplus
- The difference between what a person would be willing to pay and what he actually has to pay to buy a certain amount of a good.
- Consumption Expenditures
- The total dollar value of all goods and services purchased by the household sector for current use.
- Consumption Function
- A mathematical expression relating personal consumption expenditures to disposable income.
- Consumptive use
- That part of the water withdrawn that is evaporated, transpired, incorporated into products and crops, consumed by humans or livestock, or otherwise dispersed or not otherwise available and, therefore, is removed from the immediate water source. Consumptive use is generally equated to withdrawal minus return flow. However, consumptive use is not typically considered with regard to groundwater because such withdrawals are not typically returned to the source (i.e., to the aquifer from which it was withdrawn). Consumptive use also generally does not account for the time lag between withdrawal and return.
