Plant Growth and Soil Reaction

A large proportion of crop plants can tolerate slight to moderate acidity, a few can tolerate slightly alkaline soils, but very few are able to tolerate moderately alkaline soil conditions. There are some plants that require strongly acid soils, but all plants of agricultural value fail to grow and die in strongly alkaline soils. The preference of plants for soil [...]

Study Notes on Soil pH

Soil reaction is measured by pH (Puissance de Hydrogen) of a suspension of soil in water. The concept of soil pH may be explained with reference to pure water, which is amphoteric, and in which hydrogen and hydroxyl ions are in equilibrium with un-dissociated water molecules. The reaction of a solution represents the degree of acidity or basicity caused by [...]
