While irrigated with pulse slowly, the water diffuses at the beginning according to the capillarity and forms spheroidicity; the shapes vary from different soils. A dynamic balanced humid zone is formed according to the water evaporation, roots absorption and the infiltration without causing any salinization. With fast irrigation, the water infiltrates into the soil quickly according to the gravity and then diffuses around. Because of evaporation, this causes not only a lot waste of the fertilizer but also serious salinification and hardening of the soil.
