ABSTRACT
Soil pH is probably the most important single factor considered by both soil scientists and farmers in evaluating soil properties. Its importance is due to the fact that a simple pH determination gives an insight into soil chemical properties and suitability of soil for crops and pastures. Selection of crops according to soil pH or use of lime and other amendments to adapt soil reaction to crop requirements is a common practice. However, soils showing the same pH values do not necessarily have the same properties or limitation for plant growth, nor can the same response to pH changes be expected, depending on other soil chemical and physical characteristics.
