In the case of mineral and organic soils its direct measurement is impossible for the reason of the granular character of all soils. indirect methods based on the bundle model and the Washburn theory have to overtime its value for the reason of non-cylindrical of soil pores. Above conclusion results from the mathematical model of capillarity in non-cylindrical pores elaborated for the project purposes. This model, being a generalization of the Washburn approach, shows that pore shape impacts meniscus movement and it cannot be neglected when wetting angle is determined. Moreover it explains the nature of apparent wetting angle. Non-cylindrical of soil pres has a great significance for soil water retention
