The Gada area, located in the Mashegu area of North-Central Nigeria is known to have significant agricultural practices with the aid of chemical fertilizers and herbicides which contribute to soil salinity. However, there is lack of detailed understanding of subsurface salinization and its distribution in the region. This study aims to assess the level of subsurface salinity and its implications for agricultural activities in the area. A 2D electrical resistivity survey was conducted to probe subsurface salinization. Five profiles were acquired using Werner Schlumberger array, two profiles were acquired in agricultural farm where chemical fertilizer, insecticides and herbicides are applied, one profile in an uncultivated native vegetative land and two profiles in an uncultivated abandoned (Deserted) land. The subsurface salinity levels in the study area base on the apparent resistivity levels profile has 𝝆𝒂 (184 – 542 Ω-m) topsoil slightly saline, profile two 𝝆𝒂 (0.590 – 106 Ω-m) severely saline, profile three 𝝆𝒂 (2.549 – 449 Ω-m) partly saline, profile four 𝝆𝒂 (0.247 – 401 Ω-m) slightly saline probably leachate salinity and profile five 𝝆𝒂 (114 – 955 Ω-m) not saline mostly sandy. Based on the results profiles one and two conducted at the cultivate land are more saline followed by vegetative uncultivated land and deserted uncultivated land is not saline except in a small portion of profile four which could be a leachate salinity. The high levels of salinity in the cultivated area are possibly the effect of fertilizer, herbicides and pesticides application in the area. This salinity may adversely affect crop yield if not managed properly
