Irrigation means the action of applying water to land in order to supply crops and other plants with necessary water. Sometimes nutrients may be applied via irrigation as well. Congressional Research Service (CRS) notes that:

"Producers who irrigate in arid areas are more likely to use irrigation throughout the growing process (full irrigation), while producers in more humid areas may use irrigation to supplement rainfall and soil moisture under drought conditions."

Irrigating conventional vs. organic crops can be done via the same methods. However, it's important to remember that water conservation is a big deal.

Although organic doesn't inherently mean environmentally friendly, growers should try their best to use an irrigation method that helps conserve water and energy. For example, a producer could use wastewater or a solar-powered irrigation system which can save money, time and water.
