Availability of micronutrients in the right amount and proportion is vital for optimum nutrients ... more Availability of micronutrients in the right amount and proportion is vital for optimum nutrients utilization by diversity of plants. However, the for plants in Northern Nigeria is only for macronutrients and continuous application of one or two macronutrients may deplete the soil reserve of other nutrients; micronutrients inclusive, due to nutrients antagonism and c study was conducted to assess the profile distribution of zinc, copper, iron and manganese in selected soils of Kano state, Nigeria. Thirteen profile pits were sunk across thirteen (13) local government areas of Kano state. A total of (39) thirty nine composite samples were collected according to the pedogenic horizons at the different locations. In addition to the determination of other physical and chemical properties, available micronutrients; Cu, and Mn were extracted with 0.1N HCl and the concentration of nutrients measured with atomic absorption spectrophotometer (AAS). Data obtained were subjected to Generalized Linear Model (GLM) procedure of Statistical Analysis Software (SAS) laid down randomized complete block design (RCBD). Significantly different means were then separated using Duncan multiple range test. Results obtained revealed that although Fe and Mn contents were adequate for crop production, Zn and Cu values ranges from 0 mg kg-1 and 0.76 to 1.11 mg kg the study area as such, supplementary application of these micronutrients could be beneficial for plant diversity development. Similarly, addition of organic residues as well as including Cu and Zn in fertilizer blends to be used in soils of the study area is necessary to improve plant diversity development Sahel
