Abstract
Soil physical properties are key indicators of soil health in agricultural land. Problems related to soil physical properties often occur, especially in irrigated and rainfed corn fields. This study was conducted to understand the differences in soil physical properties between irrigated and rainfed corn fields in Beji District, Pasuruan Regency. The research focused on several essential parameters, including soil texture, aggregate stability, porosity, permeability, and organic matter content. Soil samples were collected from 20 points representing the two types of land using purposive random sampling, and then analyzed in the laboratory to determine their physical characteristics. The data obtained were statistically tested using t-tests and Mann–Whitney U tests after conducting normality tests beforehand. The results showed that soils in irrigated fields tended to have finer textures dominated by clay particles, lower aggregate stability, and slower permeability values compared to rainfed fields. In contrast, rainfed fields had looser soil structures, better porosity, and higher permeability, which supported better water movement. These differences are closely related to the more frequent waterlogging conditions in irrigated fields, which contribute to soil compaction and reduced aeration. This finding confirms that irrigation systems have a significant influence on soil physical conditions. Therefore, land management strategies tailored to the characteristics of each field such as adding organic matter and adjusting tillage practices are needed to maintain corn productivity without degrading soil quality.
