The use of surface heating with heat exchangers significantly affects the temperature regime of the soil and the surface air layer. It is manifested in a change in the distribution of temperatures according to the soil horizon, in a considerable increase in the temperature of the soil and air, in a change of heat exchange between the soil and the surface layer of air. When using tunnel greenhouse, heating the soil with the coolant temperature of 25…30 ºC contributes to the creation of all necessary conditions in ground area equipped with a heat exchangers for shifting the vegetation period of ultra-early cultivation of agricultural crops, on average, by 1-2 months depending on the crop type. This allows for earlier sowing and planting of thermophilic crops and getting harvest earlier than usual, as well as increasing the amount of crop production and improving its quality. The thermal efficiency of soil heating with water-filled flexible sleeves was studied experimentally in a field model experiment performed in the climatic terms of the Ukrainian Polissya on sandy loam and chernozem soils. Strawberry of the “Festivalny” type was used as the main crop-indicator. The influence of soil heating with heat exchangers on the growth, development and yield of strawberries has been studied.
