This study was carried out to examine the effect of plant species on soil properties in the Falgore Game Reserve (FGR) in Kano State, Nigeria; with the aim to promote sustainable conservation and management of the game reserve and to encourage the use of multiple tree species on farmlands. Strata, systematic and random sampling techniques were employed in order to capture the variability of land cover. Composite samples of soil were randomly collected at a depth of 0-30cm from sample plots of 50 m × 50 m sizes at five points using soil auger. This experiment was replicated four times. The samples were thoroughly mixed and spread out on a dry floor to air dried under the roofed shade. The samples were packaged in polythene bags and taken to the biological science laboratory (Bayero University Kano, Nigeria) for preparation and analysis. The data collected were analyzed using descriptive statistics, ANOVA and Correlation at p< 0.05. Based on this finding, shrubs and tree species diversity were found to be inversely related to soil total Nitrogen, N, % O.C and soil pH (H2O). The nitrogen content of the soil sample was more stable compared with the carbon content across the strata in the study area. The results of this finding revealed that plants species diversity have different effects on soil properties of FGR. Thus, it is recommended that conservation and restoration of threatened plant species should be encouraged for soil amendment. For easy adoption of plant species on farmlands, farmers should be enlightened more on the effects and environmental functions of trees on farm land.
