The paper deals with the problem of measuring the soil moisture by an accurate, in-situ, real-time method. Like this a mathematical model which describes a functional relationship between water content of agricultural soil and velocity of propagation of sound waves is analyzed in systematic way. After studying the conditions that guarantee the applicability of proposed model, the velocity curves relevant to different kinds of soils are determined. This model seems to be promising for moisture soil measurements in greenhouse where the soil characteristics are well known but further investigation are necessary.
