- Abstract
Laboratory study was carried out to determine some physicochemical properties and elemental composition of soil sample from Rijiyar Zaki at Ungogo LGA of Kano state to determine its nutrient value and fertility. The elemental composition was determined using Neutron Activation Analysis (N.A.A.). After activation the sample was analyzed using a high-efficiency high-purity germanium detector, the elemental concentration in the sample was determined by employing gamma spectrometry. The concentrations of K, Al, Fe, Na, Ti, Co, Mn, and Zn were obtained as 1.04±0.1%, 5±0.1%, 1.2±0.06%, 0.0749±0.0022%, 0.58±0.05%, 0.0004±0.00007%, 0.0139±0.0001%, and 0.0029±0.0007%, respectively, while Ca and Mg are below detection limit. The concentration of Al in the soil sample indicates that the soil is mineral, the low Na content implies it is non-saline which is further confirm by the result of Cl- that indicated that the soil sample is neither saline nor purely acidic. The below detection limit obtained for Ca element may be linked to the fact that with the increase of soil pH, soil base cations (such as Ca2+ and Mg2+) would precipitate with OH-, this may be the same reason for the none detection of Mg. The study of the particle size indicated that the sample is sandy clay loam, with a silt/clay ratio of 0.83 and pH of 7.4. The electrical conductivity (EC), organic carbon content, cation exchange capacity (CEC), PO43-, SO42- and Cl- content were found to be 0.15 dS/m, 0.28 g/kg, 8.40 cmol (+)kg-1, 740 ppm, 0.550 ppm and 124.3 ppm, respectively. The low silt/clay ratio indicates that the soil is made up of young parent materials with low degree of weathering, while the pH and electrical conductivity implies that the soil is normal. The low organic carbon content can be connected with high rate of decomposition under tropical and subtropical climates. The low clay content of the soil is the reason for the low value of the CEC. The low S content may be attributed to low clay and organic matter content, as well as pH higher than 6.0 of the sample.
