Laboratory Analysis: Soil texture was determined by hydrometer; pH was measured by using a pH meter in a 1:2.5 soil: water ratio. Electrical ’ conductivity (EC) was measured in water at a soil to water ratio of 1:2.5. Soil organic carbon was determined by the Walkley-Black method and total nitrogen (N) by the Kjeldahl methodv [19]. Available phosphorous (P) was determined using Bray I extraction method [19] Total exchangeable bases were determined after leaching the soils with ammonium acetate.
