A minimum slope is necessary for surface irrigation methods to ensure proper water flow and distribution across the field. A slope helps in the uniform movement of water, preventing waterlogging and facilitating efficient irrigation. A slope of 0.10% is considered a suitable minimum to achieve effective surface irrigation.
