Soil compaction, a problem threat to agriculture, has become a pressing issue in Khuzestan sugarcane fields. Subsoiling, a common practice to combat compaction, utilizes various decompactor and dozer-mounted rippers..To address this challenge, a study was conducted in two 25-hectare fields. The study aimed to identify and implement rapid and easy soil sampling techniques for a more accurate understanding of soil and the detrimental effects of conventional subsoiling practices. It also emphasized the need for a shift towards precision agriculture Sand content was generally lower than other particles, and organic matter decreased with depth in both fields. Sand content was generally lower than other particles, and organic matter decreased with depth in both fields. Moisture content varied significantly, with the lowest and highest averages observed in Field 1 (64.7% and 42.17%) and Field 2 (89.8% and 85.20%), respectively. Soil porosity was considerably low in both fields, ranging from 85.35% to 81.49%. Soil relative density ranged from 41.76% to 16.77% in Field 1 and 16.77% to 7.82% in Field 2 Analysis revealed that this method creates hard layers at depths of at least 65 cm. The average compaction across both fields was 1.6 MP, with the highest compaction occurring in the surface layer (7-20 cm), particularly along furrow paths, exceeding 3 MP. Machinery traffic, cane hauling baskets, synchronization of irrigation and harvesting seasons, and improper plowing practices. The study employed an electrohydraulic cone penetrometer to map physical properties. This method offers several advantages:, which can be used for planning precision agriculture operations.
