Irrigation


Once the Great River overtops its banks, the water needs to be channeled into the canals, to ensure water supply for the whole year. The research of Irrigation will allow building an efficient water supply system, and creating a good basis for sustainable agriculture.
Each year when a flood occurs, lots of thick rich mud is habitually driven to the banks of the Great River. This substance is an excellent natural fertilizer that makes the soil extremely fertile. As soon as the water level goes down, there is no time to lose: your field workers should be ready to plant seeds, and then immediately after begin to drive donkeys and cattle over the fields, so that they can tread over the area to firm the seeds in the soil. To make sure that the sun does not turn your fields into desert, it is vital to have an efficient irrigation system in place, though. Through the research of the modern year-round irrigation techniques your empire will be able to grow enough wheat to provide your people with food.
