Abstract
The growth of plants is a result of both macronutrients and micronutrients, which are equally important and play different vital roles. This study was designed to assess the soil characteristic, macro and micronutrients that are available in farmer field sites in Magwi County, South Sudan, which aids in understanding the future growth potential of crops. Soil samples collected from different locations in Magwi County were analyzed for soil characteristics, macronutrients, including nitrogen, phosphorous, potassium, calcium, and magnesium. Additionally, micronutrients like zinc, iron, copper, and manganese were examined. The availability of nitrogen was found to be low in almost all soil samples, while phosphorus was found to be low, medium, and high, while potassium was found to be high. All soil samples showed high levels of calcium and magnesium. The availability of micronutrients (iron, manganese, zinc, and copper) was found to be low to medium in almost all soil samples. The data reveals that in soils are deficient in macro and micronutrients which requires addition of extra fertilizer and manures to improve the overall fertility of the soil and make it suitable plantation and increase their healthy growth.
