PROBLEM TO BE SOLVED: To provide a soil heater capable of solving the problems of the loss of soil fertility and the lowering of harvest caused by the application of a large amount of chemical fertilizers and agrochemicals over a long period, friendly to the environment free from secondary damage, contributing to the health of consumers and meeting the desire of farmers to culture high-quality vegetables and fruits on a fertile ground and sufficiently supply the crop to the consumer. SOLUTION: The soil heater has a rotary drum and a semicircular heating jacket attached to a common carriage. Surface soil is raked in the apparatus (heating chamber) by traveling on a field, heated to a prescribed temperature by the combustion heat of kerosene or propane gas and returned to the ridge.
