Este estudio se llevó a cabo para determinar el estado nutricional y las formas del potasio en suelos cultivados en la Universidad de Benin. Se recogieron muestras de suelo de la granja experimental y de la zona de control a una profundidad de 0 cm a 15 cm, de 15 cm a 30 cm y de 30 cm a 45 cm utilizando un medidor de suelo. Los suelos recogidos de cada profundidad se secaron al aire, se trituraron y se tamizaron. Las muestras tamizadas se analizaron para determinar algunas propiedades físicas y químicas mediante procedimientos de laboratorio estándar. Los datos obtenidos se analizaron mediante el paquete informático Genstat con un nivel de probabilidad del 5 %. El resultado mostró que la fracción de arena (833.9 g.kg-1) era predominante en el sitio de la granja experimental. El pH (4.58) se registró en la explotación experimental en comparación con el control (4.35). El resultado mostró que (0.13 mg.kg-1) potasio soluble en agua (H2OK) fue registrado en la profundidad del suelo de 0 cm - 15 cm. El resultado mostró que el potasio intercambiable (K) (0.17 mg.kg-1) en el sitio de la Granja Experimental es superior al sitio control (0.12 mg.kg-1). El resultado medio de HCl K (0.37 mg.kg-1), K ácido (0.13 mg.kg-1), K residual (0.45 mg.kg-1) y K total (1.35 mg.kg-1) del sitio de la granja experimental fueron superiores al sitio de control HCl K (0.3 mg.kg-1), K ácido (0.12 mg.kg-1), K residual (0.39 mg.kg-1) y K total (1.18 mg.kg-1) respectivamente. El resultado mostró que las formas de potasio, H2O K, K intercambiado, HCl K, K ácido, K residual, y K total exhibieron correlaciones positivas con CE, materia orgánica (M.O), nitrógeno total (T. N), sodio (Na), potasio (K), calcio (Ca), magnesio (Mg), y fósforo medio (prom. P).
