Soil Irrigability classification is concerned with determining the feasibility of soils for irrigation based on quantitative limits of soil parameters relevant to irrigation. Land capacity categorization takes into account soil irrigation classes, topographic factors, and the location of the groundwater table to determine the overall feasibility of lands for irrigation. In this study, soil irrigability and land capability for the Paliganj distributary of the Sone irrigation scheme in India are classified using the modified approach of soil and land suitability classification suggested by Palaskar and Varade. For the present study, soil samples are collected from ten different locations at Paipura, Fathepur, Kurkuri, Sarsi, Shiyarampur, Bara, Satpura, Pipardah, Indrapuri, and Khapura. The total aggregate indices and their soil Irrigability classes for above mentioned ten locations are found to be 3.63(B), 3.76(B), 3.73(B), 3.73(B), 3.73(B), 4.71(A), 4.55(A), 4.34(A), 3.65(B), 4.78(A) respectively. After analyzing soil Irrigability classification, four locations come under none to slight soil limitation for sustain use under irrigation and the remaining six locations have moderate soil limitation for sustained use under irrigation. The land capability classes of all the ten locations come under category I, which indicates that the land is having no limitations for agriculture production. For this land classification, perennial crop percentage areas are 12 to 15 %.
