Abstract

The effects of acid treatment on some soil properties were investigated to assess the fertility of soils in both acid and non-acidic media. Six soil samples were collected around the Benue State University Makurdi. Each of the samples was divided into equal halves, the first half was leached with 0.1M HCl solution then washed with deionised water until it tested negative to 0.1M AgNO3 solution. Both soil samples were analysed; the soil pH in distilled water was 4.85-5.24 and 2.68-2.94 for the untreated and the treated soils respectively. The pH in 1M KCl of treated and untreated soils ranged from 2.10-2.22 and 3.60-4.00 respectively. An increase in exchangeable acidity of the soils was observed from 0.6-0.90 for the untreated and 3.50-5.50 for the treated samples. Acid treatment lowered the total exchangeable bases from the range 2.09-11.77 to 0.62-2.25. The values of effective cation exchange capacity of the acid treated soil samples were lower than those of the untreated samples. Titratable acidity in each case was lower than exchangeable acidity. The results reveal that soils with high acid content have lower capacity for cations than soils with low acid content hence are less valuable for cultivation.
