Abstract

Summarized data on an important scientific and applied problem, which is coming out in the development and justification of effective ways, technologies, and technical solutions of using warm waters from industry and energy in agriculture, are given. The use of surface heating with heat exchangers significantly affects the temperature regime of the soil and the surface air layer. Field research has established that heating the soil with sleeves-pipelines with a diameter of 10 cm, in which warm water with a temperature of 20...30°C circulates, increases the temperature of the arable soil layer by 12...16°C and the air layer by 7...12 °С, which provides sufficient conditions for the growth and development of plants in early spring. It has been proven that heating by sleeves-pipelines allows the period of active use of the soil to start earlier in the spring by 50-60 days for the soil protected by shelters, which helps to increase the sums of positive temperatures in the arable layer of the soil during the spring period by 1500...2000°С.
