The paper is an attempt to determine the impact of soil type and its selected technical parameters on the heat exchange with soil. The test results were based on the all-year-round experimental measurements of soil temperature and indoor and outdoor air in a greenhouse located in southern Poland. The field tests results were used to validate the calculation model using the WUFIplus software. The validation showed a high degree of conformity between the experiments and calculations. Five variants were used in the calculations, differentiated by technical parameters of the soil underneath the greenhouse. The results showed a significant impact of the soil type on the greenhouse energy management.
