Yield Factor
A factor that accounts for differences between countries in terms of land productivity. Each year, every country has yield factors for cropland, grazing land, forest and fisheries.

 


Specific Yield
The amount of water a unit volume of saturated permeable rock will yield when drained by gravity.

yield 1) The quantity of water (expressed as a rate of flow- gpm, gph, gpd, or total quantity per year- that can be collected for a given use from surface or groundwater sources.

safe yield The annual quantity of water that can be taken from a source of supply over a period of years without depleting the source beyond its ability to be replenished naturally in "wet years." ...

Quantum Yield - A measure of how efficient an emission process is. The quantum yield is a ratio of absorbed photons and photons used up in the chemical process. Quantum yield is usually dependent on temperature, pressure, and wavelength.

Optimum Yield (OY)
1. The harvest level for a species that achieves the greatest overall benefits, including economic, social, and biological considerations.

S
Safe yield. The maximum quantity of water that can be withdrawn from a groundwater basin over a long period of time without developing a condition of overdraft. Sometimes referred to as sustained yield.

Well Yield: The volume of water discharged from a well in litres per minute (L/min), litres per second (L/s),or cubic metres per day (m3/day).

sustained yield
A continual annual or perlodic yield of plants or plant material from an area; implies management practices that maintain the productive capacity of the land.

Increased yield of timber, fruit and secondary compounds - As the human population grows, more and more resources are demanded from less and less land.

safe yield The annual quantity of water that can be taken from a source of supply without depleting the source beyond its ability to be replenished. salinity The relative concentration of dissolved salts in water.

Determining the Yield of a Paper Recycling Process
Paper Recycling
Paper recycling is the process of turning waste paper (post-consumer) or scrap paper (pre-consumer) into usable products.

Surplus yield model A simple model of the impact of harvesting on a population, in which the population is represented by its size or biomass, undifferentiated into any internal structure.

31 mile (0.5 kilometer) and yields, on average, 4 inches (10 centimeters) or more in a twelve-hour period or 6 inches (15 centimeters) or more in a twenty-four-hour period. Hollow-column:a snowflake in the shape of a long, six-sided column.

Research Confirms Organic Farming Produces Higher Yields
But a spate of new research has shown that organic farming actually yields better results than modern techniques when evaluated more holistically.

one that readily ionizes in aqueous solution to yield OH anions, with a pH above 7.0, and turns litmus paper blue. Examples are oxides and hydroxides of certain metals belonging to group IA of the periodic table (Li, Na, K, Rb, Cs, Fr).

M maximum sustainable yield
Definition (english only)
1) The largest long-term average catch or yield that can be taken from a stock or stock complex under prevailing ecological and environmental conditions. 2) Maximum use that a renewable ...

Internet searches for climate change education materials yield hundreds of websites, many of which are poor in quality. Some reflect a bias that global warming is either not occurring or is nothing to be concerned about.

Natural Capital is any stock or flow of energy and matter that yields valuable goods and services that includes resources, ...

(2) That quantity of water pumped in excess of the safe yield; the act of overdrawing a water supply or aquifer in amounts greater than replenishment.

Composting: controlled microbial degradation of organic waste yielding an environmentally sound product with value as a soil ammendment.
Comprehensive Environmental Response, Compensation and Liability Act (CERCLA): See Superfund.

A substance that changes the speed or yield of a chemical reaction without being consumed or chemically changed by the chemical reaction.
Catalytic Converter ...

A process of biologically degrading organic materials in the absence of oxygen, yielding methane gas (that may be combusted to produce energy) and stabilised organic residues (that may be used as a soil additive)
Avoidance ...

Aquitard: A saturated but poorly permeable formation that does not yield water freely to a well or a spring. However, an aquitard may transmit appreciable water to or from adjacent aquifers.

A water-bearing layer of rock or sediment that is capable of yielding useable amounts of water. Drinking water and irrigation wells draw water from the underlying aquifer.
Arsenic ...

Catalyst: A substance that changes the speed or yield of a chemical reaction without being consumed or chemically changed by the chemical reaction.

See odds ratio ...

Aquifer - A water-bearing layer of soil, sand, gravel, or rock that will yield usable quantities of water to a well.

Aquifer: A geologic formation, group of formations, or part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to wells and springs.

Other Plastics- Recyclable plastic from appliances, eating utensils, plates, containers, toys, and various kinds of equipment. Does not include heavy-duty plastics such as yielding materials.

Such changes may increase the frequency and intensity of extreme weather events such as floods, droughts, heat waves, and hurricanes, change agricultural yields, cause glacier retreat, reduced summer streamflows, ...

Rather, they are deflected to the right in the northern hemisphere and to the left in the southern hemisphere, yielding clockwise and anticlockwise movements respectively.
