Potential buffer capacity of soils with respect to potassium (by the example of the Amur River region)

Thermodynamic parameters of potassium adsorption have been determined in the main soil types of the Amur River region. Potential buffer capacity with respect to potassium and the content of available potassium in a given soil type depend on the soil texture and the degree of soil cultivation. Extensive and thermodynamic parameters of the potassium status of soils are shown to be closely interrelated.
