When the hardpan is formed in the soil, crop productivity reduces due to inhibition of crop root growth, water permeability, and capillary rise, for that reason, improvement of soil physical properties is needed. Therefore, this study investigated the soil physical properties after application of various subsoil breaking method to agricultural lands to establish the effect of improving soil physical properties by subsoil breaking. The penetration resistance of the soils treated with spading (in Wanju), aeration (in Sancheong), and deep plowing (in Namwon) was lower than that of the control soil treated with conventional plowing. However, the penetration resistance of the soils treated with excavation (in Andong) and towing (in Chungju) was higher than that of the control soil. The effect of improving the soil physical properties such as increasing effective soil depth, decreasing bulk density, and increasing permeability observed in the soil subjected to spading, aeration, and deep plowing. Although, in soil treated with excavation and towing methods, it was found that the physical properties such as increasing bulk density and decreasing permeability were deteriorated due to re-compaction such as the formation of a platy structure on the topsoil by using unsuitable agricultural machinery after subsoil breaking. Therefore, the subsoil breaking cycle should be decided depending on the presence or absence of the soil hardpan in consideration of soil management histories, such as the soil moisture condition and the type and use period of agricultural machinery after subsoil breaking.
