In selecting irrigable lands, this factor can be of considerable importance. In areas to be devoted to fruit production, land should be differentiated with respect to frost hazard. This is typical practice in selecting irrigable lands on projects in the Pacific Northwest where the cropping pattern is dominated by fruit.

How does slope affect the suitability of land for irrigation?

Slope : The effect of slope on the suitability of land for irrigation is primarily influenced by the crops to be grown, the duration and intensity of rainfall, erodibilty of the soil, farm income potential, and the method of irrigation to be used.
