Abstract
This research aimed to assess the impact of termite actions on the presence of micronutrients in tropical soil. A total of five combined soil samples were gathered from various termite mounds at a depth of 0-20 cm within the premises of Kano University of Science and Technology. The samples were examined for micronutrient levels using Microplasma Atomic Emission Spectroscopy (MP-AES). The findings revealed that the pH of the mounds' soil varied from 6.63 to 8.51, averaging at 7.46, categorizing the soil as slightly acidic to moderately alkaline. The zinc levels ranged from 0.68 mg/kg to 5.38 mg/kg, with an average of 2.52 mg/kg, indicating a high zinc concentration in the soil. Iron content showed a range of 43.72 mg/kg to 121.87 mg/kg, averaging at 78.05 mg/kg, placing it in the "high" range. Manganese levels varied from 7.70 mg/kg to 88.89 mg/kg, with an average of 37.22 mg/kg, also highlighting a substantial amount. Copper concentrations in the mounds ranged from 5.52 mg/kg to 53.33 mg/kg, with an average of 29.86 mg/kg. These outcomes illustrate that termite operations impact the presence of micronutrients, notwithstanding the low organic carbon content and cation exchange capacity of the soils. As a result, it is suggested that combining termite mound soil with organic manure or fertilizers could enhance soil productivity.
