Agroforestry trees have the potential to positively influence the microclimate, and soil physicochemical properties thereby increase crop yield and grain nutrients underneath. A field experiment was executed to collect soil and grain samples from controlled plots under and outside canopy of the Faidherbia albida trees. The soil and teff grain samples were extracted using diethylene triamine penta acetic acid (DTPA) method and measured their nutrient concentration using atomic absorption spectrometry (AAS) and flame method. The collected data was analyzed using an independent sample t-test, correlation and regression analysis using SPSS and AMOS software’s. The soil micronutrients were significantly higher beneath than outside canopy of the F. albida trees. This was attributed to the existing higher soil physicochemical properties beneath the canopy of F. albida trees. Similarly, the soil physicochemical properties had significant and positive associations with the availability of soil micronutrients. Apart from the soil micronutrients, significantly higher concentrations of teff grain iron, zinc, and manganese were obtained beneath the canopy of F. albida trees. In general, F. albida trees improved the soil and teff grain micronutrients through improving the physicochemical properties of the soil underneath. Hence, agroforestry species that improve soil physicochemical properties could enhance soil and grain micronutrients.
