Abstract. The article highlights that capillary phenomena has a great importance in the life of plants. Capillaries are common in nature, for example, human hair, small blood vessels of Man and animals, very thin vessels through which the juice of plants walks, the thinnest capillaries in the soil in which water rises to its surface, air diffused and moisture-absorbing pores of bricks, pores on eggshells and the like are examples of this. Students benefit from questions and answers about the importance of capillary phenomena in agriculture. For example, the question of what to do to dry wet soil in a certain place is answered as :in order to dry the soil faster, the soil capillaries are thinned out, that is, the diameter of the capillary tubes becomes smaller. In this case, the water will evaporate, and the soil will be able to work.
