The natural medium in which most plants' roots develop is soil. Most farmers experience issues in the quality of goods acquired from specific farms over time owing to a lack of understanding about the necessity for soil testing or the usage of fertilizers for crop development. On the farmlands of Agbadabiri and Ogobiri Villages in Bayelsa State, Nigeria, nitrate, sulphate, and phosphate levels were measured. For three months, samples were obtained using an auger at various depths (from 10 cm to 30 cm). For the measurement of NO3-, SO42-, and PO43- in soil samples and control, a standard spectrophotometer was set at 470 nm, 420 nm, and 660 nm, respectively. The mean and standard deviation of the soil samples tested in various batches were calculated using Microsoft Excel. With a probability of 0.05 acceptance, a one-way ANOVA was utilized to assess the significant difference between the samples and the control. In the Ogobiri and Adagbabiri villages, the ranges in nitrate (3.25ppm–4.66ppm), sulphate (2.55ppm–5.25ppm), and phosphate (0.67ppm–3.98ppm) were found for both farmlands and control. The results revealed that nutrient concentrations were below standard, necessitating the application of fertilizer to boost nutrient availability.
