A study of soil characteristics dryland productivity of the Supiturung Micro Watershed, Kediri Regency, was conducted by observing the physical conditions of the environment and identifying the morphological and physical properties of the soil in each horizon in the soil profile. Parameters observed were physical properties (texture, bulk density) and chemical properties (CEC, total N, organic C, and base saturation). Data on soil characteristics and plant productivity were then analyzed by correlation and regression to determine the relationship between the two. The results showed that the soil in the study area belongs to the order Inceptisols and Entisols with the dominant subgroup Typic Humudepts. Pineapple plants were spread at SST 5, 7, 9, and 10 with the productivity of 71.18%, 76.35%, 75.76%, and 72%, respectively. Meanwhile, sugarcane was spread in SPL 1, 2, 3, 4, 6, and 8 with the productivity of 71%, 77%, 73.43%, 76.29, and 70.81%, respectively. The results of the analysis show that the land characteristics that affect the productivity of pineapple plants are sand texture with a correlation coefficient value of 0.84 and a regression of 0.71 with a linear equation y= -0.07x + 67.57 R² = 0.53 Land with a sand texture class increasingly has low productivity.
