Why irrigation method depends upon the type of crop, weather condition, and type of soil?

Irrigation is the supply of water to crops at regular intervals. The frequency of irrigation is based on the type of crop, soil, and season. 

For example, crops like paddy require more water. While other crops may require less water.

Irrigation also depends upon the type of soil as sandy soils have less water retention capacity so need more water. While clay soil or black soil have more water retention capacity, thus require less water.

Similarly, summers demand frequent watering of crops due to the increased rate of evaporation compared to winter and rainy seasons.
