Soil pH influences several chemical and biological processes in the soil environment. It is critical in crop productivity as it impacts plant nutrient availability from sufficiency to deficiency and potentially toxicity. Crop growth problems are common in soils with pH below or above optimum ranges. Evaluating and managing adverse soil conditions in which pH tends to be a major factor can be challenging. Those challenging stuations, including alkaline, saline, sodic, and saline/sodic soils will be discussed. Each condition presents unique challenges to minimizing its crop yield limiting effects. Sulphur can be employed to manage these soil conditions.
