What is an Aquifer?
Pore spaces found within permeable layers of rock and sediment underneath the soil that store groundwater
Aquifers are crucial for supplying water to wells and springs.
Define Unconfined aquifer.
An area surrounding a well that does not contain groundwater
Unconfined aquifers are directly recharged by surface water.
What is a Confined aquifer?
Surrounded by a layer of impermeable rock or clay, which impedes water flow to or from the aquifer
Confined aquifers can store water under pressure.
What does Water table refer to?
The uppermost level at which the groundwater in a given area fully saturates the rock or soil
The water table can fluctuate based on seasonal changes and water usage.
What is Groundwater recharge?
The process by which water from precipitation percolates through the soil into groundwater
Recharge is essential for maintaining aquifer levels.
What is a Spring?
Water that naturally percolates up to the surface
Springs can be a source of freshwater in many ecosystems.
Define Artesian well.
A well created by drilling a hole into a confined aquifer
Artesian wells can flow without pumping due to pressure.
What does Water footprint mean?
Total daily per capita use of fresh water for a country or the world
It reflects the water consumption associated with individual or collective activities.
What is Furrow irrigation?
A form of irrigation where the farmer digs trenches, or furrows, along the crop rows and fills them with water
This method is efficient for row crops.
Define Flood irrigation.
A form of irrigation where an entire field is flooded with water
Flood irrigation can lead to water wastage if not managed properly.
What does Spray irrigation involve?
A form of irrigation where water is pumped into an apparatus that contains a series of spray nozzles
This method mimics natural rainfall.
What is Drip irrigation?
A form of irrigation where a slowly dripping hose on the ground or buried beneath the soil delivers water directly to the plant roots
Drip irrigation is highly efficient and conserves water.
What are Persistent pesticides?
Pesticides that remain in the environment for years to decades
Their long-lasting presence can lead to environmental and health concerns.
Define Nonpersistent pesticides.
Pesticides that break down relatively rapidly, usually in weeks to months
They have fewer long-term effects but may require more frequent applications.
What is a Fungicide?
A pesticide that specifically targets fungi (the plural of fungus)
Fungicides are used in agriculture to protect crops from fungal diseases.
What does Rodenticide refer to?
A pesticide that specifically targets rodents
Rodenticides are commonly used in pest control.
What is Pesticide resistance?
A trait possessed by certain individuals that are exposed to a pesticide and survive
Resistance can lead to the ineffectiveness of certain pesticides over time.
What is Integrated pest management (IPM)?
An agricultural practice that uses a variety of techniques to minimize pesticide inputs
IPM promotes sustainable agriculture by combining biological, cultural, and chemical practices.
