The specific heat is an important characteristic of soils at their application as the bases of buildings and engineering structures. The article presents the experimental data on specific heat of the Amginsky deposits clay soil in the Republic of Sakha (Yakutia) in the range from sorption humidity to upper limit of plasticity obtained by the differential scanning calorimetry Sensys Evo TG-DSC. The specific heat measurements were carried out on samples of clay soil taken directly from the deposit and samples of the same soil, but previously cleaned of impurities. It is established that for clay soil the dependence of the specific heat capacity on humidity is not monotonous but has a maximum
