Providing land with water through a network of canals is irrigation. Irrigation is the practice of delivering water to fields to keep the soil moist and support crop growth, especially when rainfall is insufficient. Canals are a common way to move water from rivers or reservoirs to multiple fields, giving farmers control over when and how much water crops receive.

Manure is used to improve soil fertility and organic matter, not to supply water. Fertilizer adds nutrients to the soil to boost growth, but it doesn’t water the land. Seeds are planted material; irrigation may help them establish, but the process described is specifically about providing water, which is irrigation.
