This study evaluates the patterns in nutrients, grain size, and allied matters’ distributions across geomorphic hazards vulnerable sites in Edo State to strengthen sustainable management efforts and boost land capability for agricultural uses. The specific objectives include determining the patterns of variations and relationships among the soil nutrients and allied parameters across distinct geomorphic hazards vulnerable sites. Soil samples were collected from 12 gullies and 3 flood-vulnerable sites using a soil auger and sediment corer, treated, homogenized, and analyzed in the laboratory for diverse parameters. The laboratory results were further analyzed using descriptive and inferential statistics. The grain size distributions reveal spatial fluxes, but with the unilateral dominance of sand particles. A test of multiple effects of variations in locations on nutrient endowments using Hotelling's Trace model gave a value of 13,868.621 and an F value of 3467.155 that is statistically significant at 0.013. Roy's Largest Root model offered a high value of 1850.015 and a high F value of 740.006, which is statistically significant at 0.000. The tests of variations between-subjects indicate that only phosphorus, calcium, and magnesium possessed high values that are statistically significant at a 0.05 confidence level. This study concluded that soil chemistry and granulometry in the geomorphic hazard vulnerable sites varied based on geographic locations, due to the uniqueness of the intervening human and natural agents. This study recommends the adoption of proactive people-oriented and site-specific engineering and supportive agronomic management strategies for enhanced land capability for sustainable crop production.
