How is good water management beneficial for farming?
Farmers apply water to crops to stabilize and raise yields and to increase the number of crops grown per year. Globally, irrigated yields are two to three times greater than rainfed yields. Thus, a reliable and flexible supply of water is vital for high value, high-input cropping systems.
What are the irrigation techniques?
The three main methods of irrigation are surface, sprinkler, and drip or microirrigation. In surface irrigation, water flows over the soil by gravity. Sprinkler irrigation applies water to soil by sprinkling or spraying water droplets from fixed or moving systems.

These chemicals can be passed into the drip tapes with fertigation equipments like the venture injector or dosing pump.
How successful is drip irrigation?

What are the pros and cons of flood irrigation?
|Low initial investment for equipment is required||Least efficient form of irrigation. More water loss from evaporation, infiltration, and runoff|
|Runoff water can be recycled to improve efficiency||Building and taking down levees is labor intensive|
Does flood irrigation cause salinization?
At the end of each irrigation (flood, basin and border) cycle, the soil dries out and the salts are concentrated, adversely affecting the crop yield. Frequent irrigation may lower the salinity, but it wastes water.
