ABSTRACT

The study investigated the spatial distribution of soil nutrients in Etche.The management of soil nutrients in Etche for optimum productivity requires the understanding of their levels and distribution. This study evaluates the distribution of some macro and micro-nutrients in the soil. Sixty soil samples form different locations in Etche were collected at the depth of 0-30cm and analyzed for nitrogen (N), phosphorus (P), potassium (K), total iron (Fe), total zinc (Zn), total copper Cu, and total manganese (Mn). Mean, standard deviation and coefficient of variation were used to evaluate the level and variability of the nutrients. N (0.080 to 0.170%) were below the critical level while P and K levels (5.44 to 4.320ppm and 0.210 to 0.480 cmol/kg respectively) were moderate, there variation (CV = 24.11%, 30.10%, and 22.19% respectively) were moderate across the landscape. Fe has means of 3.6355mg/kg, minimum value of 2.100 mg/kg, maximum value of 5.67 mg/kg; they are rated moderate. Cu has mean value of 0.885mg/kg and maximum value of 7.510 mg/kg; they are rated low. Zn has a mean value of 22.409mg/kg, minimum value of 16.380mg/kg and maximum value of 29.750mg/kg; the values are considered to be low. Mn has mean value of 268.33mg/kg, minimum value 210.000mg/kg and maximum value is 415.000mg/kg; the values are rated high. The distributions of the nutrients are influenced by cultivation, cropping pattern crop type, leaching and erosion. Compound fertilizers containing micro nutrients should be used for crops in the location, fertilization with different ratios of NPK. should be done for different portion of the land with reference to their distribution.
