ABSTRACT

The fertility status of Alfisols, Incepptisols and Entisols in the Gubi soil series were evaluated. The soils were generally slightly acid to moderately acid and the pH was significantly (p<0.01) higher in the lower horizons than in the surface horizons. Exchangeable acidity was low in the Alfisols and Inceptisols and high in one profile of the Entisols with a significant (p<0.01) difference between the profile contents. Exchangeable bases were high to medium in the Alfisols, while in the Inceptisols calcium content was high; magnesium medium, potassium and sodium were low. In the Entisols, calcium content was high with medium magnesium and sodium contents and low potassium. Magnesium and sodium were significantly (p<0.01 and p<0.05) different between profiles. The sodium, content of the three soil orders was also significantly (p<0.01) different, Entisols had significantly higher values than the other soils. Cation Exchange Capacity was medium to high in Alfisols and medium in the Inceptisols and Entisols while base saturation was medium in the Alfisols and Inceptisols and high (statistically p<0.01 different) in the Entisols. Organic carbon, total nitrogen and available phosphorus were generally low across the soil orders. Intensive cultivation with increase use of organic matter and careful application of inorganic fertilizers is suggested for optimum crop production.
