Knowing the PH level of the soil is important for farmers and gardeners t ensure healthy growth of their plants and crops. The PH level determines the hydrogen and hydroxide levels in the soils. Some plants require a more acidic soil while others prefer a base soil. Gardners can use sulfur or aluminum sulfate to lower the PH level of the soil, or lime to increase the PH level to make it less acidic.
