Well water (groundwater)
Microirrigation (drip and microspray)
Applies the water through small emitter to the soil surface; drip irrigation allows the water to drip slowly to the roots of plants minimizing the water evaporation; microspray applies water to the soil surface by a small spray or mist
Farm of conventional cultivation
Manual with manure
River water (surface water)
Sprinklers
Sprinkler irrigation is a method similar to natural rainfall; water is delivered through a pressurized pipe network to sprinklers which spray the water into the air
