Irrigation Flashcards
Furrow
Dig trench next to the crops with water and let it deep into the soil
Flood
Flood entire field. Can water log and drown plants.
(80%)
Spray
Water pumped into spray nozzles. Expensive, needs energy.
(75%)
Drip
Holes in hose allow water to drip out. Conserves water, most expensive.
(95%)
Soil salinization
Excessive accumulation of water-soluble salts.
Solutions:
- Treat water before use
- use freshwater source
- aerate soil
GM drought-resistant crops
lessens dependency on irrigation and reduces water consumption.
Ogallala Aquifer
Essential to crop production in Midwest, being used faster than can recharge
Desertification
process of once productive areas being deserts due to repeated hit to soil integrity. Irreversible.
